How Technology Manufacturers Use Chemical Delivery Systems


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]
