How to Select a Supplier from Your List of Semiconductor Equipment Manufacturers

How to Select a Supplier from Your List of Semiconductor Equipment ManufacturersWhen choosing a supplier from a list of semiconductor equipment manufacturers you have to look at a wide variety of factors. Key points to evaluate include the following:

  • Customization capabilities to meet customer requirements
  • Equipment reliability
  • Company experience and expertise
  • Warranties
  • Service and customer support

Only after you have determined which manufacturers can actually supply the equipment you want can you look at cost of ownership and pricing to make your final decision.

Specifying What You Need

Semiconductor fabrication lines and research labs are different and have specific requirements when they want to upgrade lines, replace components or buy new equipment. Sometimes the purchased equipment has to interface with existing systems, sometimes space is a factor and sometimes the physical set-up of the production facilities limit what can be installed. A supplier has to be able to evaluate these constraints and suggest solutions. The equipment proposed often has to be customized to some extent and the supplier has to have the experience and the capability to adapt his standard solutions to particular situations.

Equipment Reliability

Once you have purchased your equipment, it has to keep working with a minimum of downtime. The best way to evaluate the reliability of a supplier’s equipment is to ask for references and reliability statistics. Suppliers should submit normal hours of scheduled downtime, estimates of unexpected downtime and the records of actual installations. Once you have narrowed down the list of suppliers, it’s a good idea to check with some of the references who are not direct competitors of your company and verify what the supplier has submitted.

Warranties, Service and Support

Before you sign a contract with a selected supplier, check on his equipment warranties and his service and support capabilities. Warranties should be simple, comprehensive and of sufficient length. Check on whether the supplier has enough service personnel. Also important is whether he can rely on his own personnel to carry out service or whether he has to call in third parties. If a supplier subcontracts a lot of his equipment manufacturing, he is less likely to have competent service personnel on staff to deal with that equipment. Call support to see how they respond to support requests. Often calling a supplier’s customer support line with an equipment question rather than going through your contacts in sales will give you an idea how well a supplier responds to support requests.

Conclusion

The selection of the right semiconductor manufacturing equipment supplier for additions to a fabrication line or a research lab affects future productivity and output quality. You have to make sure you buy the equipment you need and select a supplier who will keep it working optimally.

How the Silicon Nitride Etch Process Is Supported By Modutek

The silicon nitride etch process is used in the manufacture of integrated circuits to selectively remove silicon nitride with respect to silicon oxide. Engineers and process specialists in the industry who work with semiconductor equipment manufacturers owe a great deal of their expertise to the quality of the etching equipment at their disposal today.

Background

Integrated circuit fabrication processes include selectively removing silicon nitride using wet or dry etching. Selectivity between materials removed and not removed should be high. However, selectivity is not the only consideration, in a manufacturing environment a process engineer needs consistent and repeatable results from high quality and reliable equipment.

Field Oxides Provide Mask Layer

Field oxides deposit a dielectric mask layer over silicon using a patterning mask layer exposing the silicon or oxide, and growing the thick oxide called field oxide. The preferred choice of dielectric for the mask layer is silicon nitride. This process is LOCOS, Localized Oxidation of Silicon. A poly silicon layer is frequently present beneath the nitride. This is a Poly Buffered LOCOS stack. Thus, both silicon nitride and poly silicon must be removed without affecting the silicon oxide.

Aging Effects and High Particle Count

Wet etching techniques are used for stripping nitride and silicon when oxides are present. Silicon nitride is etched in phosphoric acid that is boiling. Amounts of nitric acid may be in the bath. These baths are susceptible to aging and having higher particle counts because the silicate concentration in the bath increases. Others use separate baths for nitride and poly silicon. This increases the number of baths required and can lead to pitting of the pad oxide, which engineers overcome by using a bath with phosphoric, hydrofluoric, and nitric acids. Bath life is extended by hydrofluoric and nitric acids. Nitric acid is required to oxidize silicon. The initial etching selectivity of nitride to oxide may be undesirably low, selectivities of 9:1 observed, and depends on fluorine concentration. Higher initial etch selectivities are preferred.
Before etching silicon nitride or poly silicon to silicon oxide, you should add silicon to the etch process bath. The silicon enhances initial etch selectivity. Fluorosilicates also can be used. These compounds dissolve readily in phosphoric acid without particles. The compounds increase the etch selectivities to 40:1 and 33:1 for silicon nitride and poly silicon. The additional silicon stabilizes may be in the bath from initial use until its use is terminated. Variations of this procedure are tested and reviewed by engineers and researchers.

Equipment Innovations

IC equipment suppliers provide manufacturers and researchers with leading edge products required for producing smaller geometry semiconductors, thin-film heads, and MEMS, and also need to offer service, support, and retrofitted systems. These products are usually designed to meet specific requirements of manufacturers.

Silicon Nitride Etch Baths that Provide Safety, Control and Flexibility

The Nb Series Operation Process used with Modutek’s silicon nitride etch bath guarantees process control, safety and flexibility with a two-level diagnostic system monitoring temperature while maintaining acid to water ratio through D.I. water supplementation. By using a new remote metering system, the Nb Series is easy to install and service in new or existing stations. Process engineers know that this kind of equipment needs to be manufactured and supported by a company that:

  • Has extensive experience and expertise;

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.
