About Us

Meeting the Needs of Innovative Process Engineers
Located in Livermore, California, Yield Engineering Systems (YES) is a privately held company that manufactures engineering process control equipment to meet the needs of innovative engineers and lab managers. YES designs and builds high temperature vacuum cure ovens, chemical vapor deposition (CVD) systems, and plasma etching tools used for precise surface modification and thin film coating of semiconductor wafers, MEMS and bioMEMS devices, biosensors, medical slides and silicon chips used for microarrays (DNA, protein, gene, tissue, and antibody).

Building Equipment to Increase Yields & Extend Device Performance

YES systems achieve precise surface modification and cleaning in order to increase yields and extend the life and performance of devices. YES systems are designed to meet today's most demanding process applications and provide stringent environmental control, so you get the results you want. Additionally, YES systems provide the flexibility needed by research and design engineers, while achieving the simplicity of recipe needed for the manufacturing line. Our equipment can grow with your process, from R&D to pilot line to high volume manufacturing.

Providing Customers with Improved Processes

Our goal is to provide customers with improved processes, not just great tools. We have a complete staff of process, design, mechanical, electrical, software and service engineers ready to assist with your process needs. All our work is done in house—we do not outsource. This keeps our resources close at hand when you need us.

30 Years of Experience

For 30 years, listening to our customers has driven our new product development. Responding to the needs of innovative process engineers is more than our business model--it's our passion.
