What Fume Scrubbers Do and the Benefits They Provide

What Acid Fume Scrubbers Do and the Benefits They ProvideManufacturing processes such as semiconductor etching or the cleaning of parts with strong chemical solvents generate exhaust fumes containing the process chemicals in gaseous or droplet form. Such fumes have to be neutralized before they can be released into the atmosphere or into the air inside the manufacturing or research facility. The fumes are harmful to human health and may be corrosive to plant machinery. Companies face fines if they release fumes into the outside atmosphere and may contravene labor standards if the fumes reach the factory floor or lab work areas.

Modutek’s Acid Fume Scrubbers use a wet packed bed to remove acid and base chemical traces in chemical process exhaust fumes. The fumes pass over wet packing material and the chemicals are removed as they come into contact with a neutralizing solution in the beds. Well-designed fume scrubber beds expose the fumes to a large surface area covered in neutralizing solution. The harmful gases dissolve in the solution, are neutralized and are no longer present in the air. A wide range of fume volume handling capability makes the Modutek fume scrubbers suitable for all kinds of manufacturing facilities and university or company research labs.

Custom Designs

Modutek offers a wide range of models to address the various fume scrubbing requirements that customers may have. Air handling capacities range from 500 CFM to 25,000 CFM and each scrubber is designed to meet the customer’s air quality standards. The scrubbers come with a NEMA 4 control cabinet, a complete set of flow and pressure gauges, control of the scrubber water level and a metered discharge. Seismic and structural certification is available. The scrubber models have the flexibility to meet many requirements such as treating air from acid exhaust hoods, plating stations, precision cleaning stations and wet benches.

High Efficiency

Modutek’s Fume Scrubbers operate at high efficiencies to neutralize chemical fumes from exhaust air and minimize water usage. Automatic pH control of the scrubber water optimizes operation and allows removal of acid and base chemical fumes of up to 99 percent. The scrubbers use packing material from packing media industry leader Lantec to maximize the surface area of the scrubber solution exposed to the fume gases and reduce water usage to a minimum.

Modutek Acid Fume Scrubber Features

Acid Fume scrubbers from Modutek are designed for low cost of ownership with a low use of consumables. A bottom drain and the Lantec packing material facilitate maintenance. The scrubbers are made of black polypropylene with UV protection and they feature double containment for extra safety.

To ensure and maintain efficient operation, the scrubbers recirculate the scrubber water and feature a demister section and removal of water-soluble vapor. These features together with the design flexibility of the scrubbers and the company’s capability to offer highly customized units make Modutek’s Acid Fume Scrubbers an excellent choice for use in many factories and labs. Manufacturing processes such as semiconductor fabrication and biomedical devices as well as research labs using chemical processes can make sure that they maintain the clean air quality they need.

How Technology Manufacturers Use Chemical Delivery Systems

How-Chemical-Delivery-Systems-are-Used-by-Technology-Manufacturers

Technology manufacturing requires the safe handling of chemicals as well as their delivery in accurate amounts. Corrosive chemicals are used for etching, cleaning and plating materials such as silicon chips, metal parts, solar system components and printed circuit boards. The chemicals have to be stored securely, delivered to the process in precise amounts, and neutralized before disposal. Automated chemical delivery systems reduce waste and operator error while allowing the supply of defined amounts of each chemical with a high degree of precision.

Technology manufacturers use these systems to supply chemicals to wet processing equipment. Acids are used to etch away layers of material on wafers of silicon, printed circuit boards or other substrates. Sections of the layers to be etched are covered in protective material and are not removed by the etching. In this way microscopic structures and conducting paths can be created. The requirements for chemical delivery systems depend on the application of the wet processing equipment and on the chemicals to be used.

The key to supplying effective chemical delivery systems is a flexible approach combined with the ability to develop systems customized to meet the needs of the manufacturer. Companies that manufacture silicon wafers have different requirements from those that manufacture micro-electro-mechanical systems, hard disk drives or solar cells. The cleaning and etching processes of different technology manufacturers use various chemicals and widely varying amounts and process control strategies. Their chemical delivery systems must be resistant to corrosion, be safe to operate, allow the storage of large amounts of chemicals and include flexible software to control distribution. An equipment supplier has to have a good understanding of the processes involved so that they can standardize the parts of the system that can remain the same while developing custom solutions to match the needs of each technology manufacturer.

Modutek specializes in designing and manufacturing systems that provide outstanding performance and reliability with the ability to be highly customizable. The systems incorporate user-friendly features that promote safe and cost-effective operation. In a typical custom application, water use, and the number of defective parts produced is reduced while consistency of results increases.

Modutek’s chemical delivery systems feature all Teflon fluid paths, double containment cabinet construction, leak detection and chemical level sensing. Double wall plumbing and system data logging are available. Chemical storage can be in large tote chemical containers or 55-gallon drums close to the wet process station. Manufacturers that use different chemicals can improve throughput because the Modutek’s systems are designed for quick chemical change.

The software that automates a chemical delivery system is a key factor in the system’s flexibility and Modutek can customize the software to meet the needs of the technology manufacturer. Typically a touch screen shows error messages on start-up and then displays a flow diagram showing the status of key components such as metering pumps, valves and level switches. Since these may be different for particular customized applications, the software must be easily adaptable. All the software for Modutek’s chemical delivery systems is written in house. This means that Modutek has the in house expertise and capability to make changes in the software as needed and can provide excellent technical support without having to rely on exterior sources.

The Modutek chemical delivery systems are suitable for any technology manufacturer application. They are specifically designed for easy customization and provide reliable, cost-effective operation. For additional information about Modutek’s Chemical Delivery Systems or related products call 866-803-1533 or email [email protected]

Benefits of Using Modutek Acid Neutralization Systems

Benefits of Using Modutek Acid Neutralization SystemsAcid neutralization systems adjust the pH value of a process stream in self-contained systems, either continuously or in batches. Effluent monitoring ensures that automatic discharges take place only when the pH values are within set limits. The systems are easy to install with high efficiency and low cost operation. A wide variety of available sizes allows accurate matching to the requirements of particular applications.

Normally acid neutralization systems adjust the pH of a process discharge to within adjustable limits, depending on the application. When discharged into a public sewer, neutralization within a pH range of 6 to 9 is typical. For mildly acidic or alkaline streams with high flow rates and stable characteristics, compact and low cost continuous flow neutralization can be used. When the pH levels fluctuate, inflows are irregular or when the flows are highly acid or alkaline, the use of batch systems is appropriate. These systems neutralize the particular batch and only allow a discharge when the set criteria are reached. A final monitoring chamber for sampling and for recording discharge pH gives operators full control of the effluents.

Flexible Application

Modutek’s acid neutralization systems are available in a wide variety of sizes and configurations. They are designed to suit the requirements of different production facilities and applications, including for semiconductor fabrication, in research centers and in universities. Sizes range from 5 to 500 gpm and installation can be indoor or outdoor, depending on availability of plumbing and electrical connections. The self-contained units are compact and easy to install with an on board reagent tank option. Systems up to 100 gpm are of unitized construction with steel reinforced thermo welded polypropylene while larger systems are skid-mounted.

System Features and Characteristics

Modutek designs its systems with an emphasis on safety and reliability while keeping costs low and saving space. Neutralization systems can operate in fully automatic mode for both acid and alkaline streams. Secondary containment is standard and automatic mode ensures that discharge only occurs when the stream is within permitted pH values. For normal operation, a two-stage system is usually sufficient but three-stage systems are available for especially demanding applications. The control system requires a 120 V AC supply but the mixers and pumps can operate on 120 V or 208 V AC.

The control of the process stream pH is micro-processor based while alarms are handled by a PLC with a touch screen. This combination results in high accuracy and reliability while making it easy to calibrate the sensors and adjust the set points. Neutralizing chemicals are injected into the process with two metering pumps for each stage. Larger systems add pressure control valves.

Alarms include high and low pH in the final monitoring chamber and low level in the reagent storage tanks. There is a liquid sensor in the double containment and all the alarms can be tied into relays for remote signaling at the control panel. Ethernet access for remote signaling is also available and a digital chart recorder monitors and tracks the pH of the process discharge. As a result, there is a continuous record of the pH levels and of alarm conditions during automatic operation.

Overall Benefits

Modutek’s acid neutralization systems offer operators handling chemicals a complete range of neutralization options and system sizes in convenient configurations. The low cost systems are inexpensive to install and reliably ensure that process streams stay within required pH ranges. While operation is fully automatic, comprehensive alarms and monitoring lets the operator check that the system is functioning as intended. If you need more information or would like a quote for your specific requirements contact Modutek by calling 866-803-1533 or sending an email to [email protected]

How to Develop a Requirements List When Buying Wet Bench Equipment

How-to-Develop-a-Requirements-List-When-Buying-Wet-Bench-EquipmentChoosing the right wet bench equipment is a huge challenge for a manufacturing company or research facility. The equipment represents a major investment and you don’t want to spend a lot of money to find out the system doesn’t meet all your requirements. Secondly, the complex nature of wet bench equipment often makes the selection process even more difficult. In many cases, wet benches are designed to handle specific processes for wafer manufacturing. You need to insure that the equipment can support all your chemical processing and through put requirements.

That’s why you need to carefully evaluate your needs as you prepare to buy a wet bench. Below are 7 things you need to consider when buying wet bench equipment.

  • Wafer or substrate size

Before you even think about the equipment you want to buy, consider what wafer or substrate sizes it can handle. Different applications utilize different processes and wafer sizes, which applications do you need? Fortunately Modutek’s wet bench stations can handle all manufacturing process and wafer sizes up to 12″, whichever wet station you choose; manual, automated, or semi-automated.

  • Cassettes per bath

How many wafer cassettes per bath can the wet bench equipment hold? Some equipment can hold 2 wafer cassettes per bath; others can only hold one cassette per bath. An even more important feature is how the wafers are moved between baths. In some equipment, the movement is manual while in others it is automatic.

  • Is FM approval required?

FM Global Standards form the basis approval assessment of manufacturing equipment used in the semiconductor industry. It is a general understanding in the industry that equipment addressed as FM Standard are custom built rather than produced in mass. The manufacturer’s ability to produce consistently standard products is assessed on a regular basis during FM Approval’s product follow-up program.

  • Is CO2 fire system required?

Considering the fire risk posed by wet bench processes when solvents are used, most manufacturers fit their equipment with fire extinguisher systems. A common trend is to fit the equipment with CO2 fire suppression systems (Acid benches do not require CO2). See if the fire extinguisher suppresses fires without leaving behind foam, water, or dry chemical that may damage sensitive equipment parts.

  • Is a third party electrical inspection needed?

SEMI S2, CE, and 3rd party tests are an excellent way to test your system for consistency and efficiency. Modutek uses SEMI S2, NFPA, and NEC as guidelines in manufacturing wet processing equipment and can also provide a quotation for inspection reports as requested. You’re guaranteed that all systems will pass 3rd party electrical inspections.

  • Wafer volume requirements per day/week

How many wafers do you expect to process per day/week? As most process engineers have discovered, Modutek’s dry-to-dry wet processing equipment eliminates the need to dry using a separate tool. Fitted with an MVD Series IPA Dryer, the equipment shortens overall manufacturing process allowing for greater yield per unit time.

  • Exhaust/chemical fume hood filtration requirements

Since hazardous fumes are produced in wet bench process, an exhaust mechanism is critical to all processes. Modutek provides a chemical fume hood that gives you a quick and low cost means to dispose of hazardous chemicals from the work station. Featuring white polypropylene construction for base and acid processes and stainless steel construction for solvent applications, the fume hoods are easy to install and set up, low cost, and meet or exceed all safety standards.

Summary

Remember that you always have the choice of manual, semi-automatic, and automatic wet bench stations. Other factors you may need to consider include: pump requirements, in-line heater needs, and station layout. For more information, contact Modutek on 866-803-1533 or 408-362-2000.

5 Things About Wet Benches You Should Know

wet benches

As a Process Engineer you probably know a lot about using wet benches and chemical stations. You know that wet benches are for wet etching and that a very precise process needs to be maintained for cleaning wafers and devices. You also know the difference between wet benches and litho benches. While wet benches are used for wet etching, litho benches are used for resist processing.

However, there may be a number of other things you’re yet to know about wet benches. Here are 5 things you need to know about wet benches;

 

 

  • Manual vs. semi automatic vs. automatic wet benches

Advanced manufacturers like Modutek also have manual, automatic, and semi-automatic wafer benches. The main difference comes in operation. Manual wet benches are operated 100% manually. However, the wet benches are still exhaustive featuring all the functionalities you may need. Moreover, you can request custom designs and processes. Modutek’s semi-automated wet benches are servo controlled with 3 degrees of freedom which gives you precise developing, etching, and cleaning processes. Fully automated wet benches are the most expensive of the three but also the most extensive in design. Complete with SolidWorks Simulation Professional and SolidWorks Flow Simulation Software, these wet benches complete most tasks with ease.

  • Dry-to-Dry wet benches eliminate the need to dry in separate tools

Dry-to-Dry wet benches are your ultimate tool. Modutek’s dry-to-dry wet benches utilize the MVD Series IPA Dryer. With this Dryer, your wafer comes out dried and can proceed to the next step without going through a separate Drying tool. This instantly eliminates transfer time which is in affective way to improve throughput.

  • The stainless steel solvent station guarantees clean room applications

Modutek currently has a dry-to-dry stainless steel solvent station in which solvent applications are achieved with minimal strain. Made from 304 stainless-steel, the construction is available for manual, semi-automatic, as well as fully-automated applications. Complete with SolidWorks Flow Simulation and SolidWorks Simulation Professional, the solvent station provides high etch rates and increased throughput. Moreover all the robotic parts to be designed and assembled and tested at Modutek’s San Jose facility. Modutek provides highly reliable equipment with a one year guarantee.

  • Wet benches can be hazardous

For all their benefits, wet benches can be hazardous and must be handled carefully throughout. Hydrogen fluoride which is present in the acids used in wet bench processes may cause delayed tissue damage upon contact with the skin. It depletes of calcium from muscles and bones. When working with wet benches, it’s important to wear appropriate gloves (such as chemical resistant Nitrile clean-room gloves) at all time. Additional protective gear including face shields and chemical aprons are also recommended.

  • You can actually nullify some of the threat using a chemical fume hood

While it’s almost impossible to eliminate all the risks posed by the chemicals and processes associated with wet benches, you can always use a fume hood to increase safety at the workplace. Modutek’s chemical fume hood is constructed from standard polypropylene and supports both acids and bases. The hood comes complete with utility sinks, GFI electrical outlets, and a goose neck faucet. It’s easy to install though you can always contact Modutek for assistance. You can even request a custom design.

Acid Neutralization Systems from Modutek

Acid Neutralization SystemModutek Corporation designs and manufactures a complete line of self contained industrial waste acid neutralization systems that are easy to install and inexpensive to operate. Batch sequence reactor systems as well as Continuous flow neutralization systems are also available.

The task of all neutralization systems is to adjust the pH of the process stream to a defined acceptable discharge range. Normally adjusting the pH balance to a neutral range from 6 to 9 pH is what most industrial applications are held to before discharging water into the public sewer. Generally continuous flow neutralization systems are well suited for relatively high flows of mildly acidic or alkaline (e.g. 2.0 < pH < 12.0) waste water. Compared to batching systems continuous systems are smaller and less costly, however, they are also more limited. For more demanding industrial applications, such as those with fluctuating pH balance flows or those characterized by highly acidic or highly alkaline waste water, a batch system would be the better choice since it only discharges when the treated effluent meets a specific discharge criteria.

Applications where continuous flow neutralization systems are typically used include:

  • Influent chemistry is relatively constant and not characterized by large swings with incoming pH or chemistry
  • Influent flow is relatively constant and not characterized by large flow surges
  • Used as a single stage in a more complex application such as fluoride removal or heavy metal reduction
  • Effluent pH limit is not highly constrained (range of < 2.0 pH units)

Continuous Flow Neutralization systems

Modutek offers compact two and three stage continuous flow neutralization systems that are completely self-contained. They provide fully automatic operation and use a compact design in either single or double containment and range in size from 5 to 500 gpm.
