Yield Engineering Systems (YES) builds process control equipment to serve the needs of the semiconductor, biotech, and nanotech industries. YES equipment enables precise surface modification–surface cleaning, process curing, and thin film coating. Depending on your need, surfaces can be super water resistant (hydrophobic) or adhesive (hydrophilic).

Applications include photoresist adhesion for semiconductor wafer fabrication, MEMS coatings to reduce static friction (anti-stiction), bioMEMS coating to promote biocompatibility, and modification of silicon chips and slides used for microarray processing (DNA, gene, protein, tissue, antibodies).

YES (Yield Engineering Systems, Inc.) is a leading manufacturer of high-tech, cost-effective equipment for transforming surfaces, materials and interfaces. The company’s product lines include 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, semiconductor and MEMS devices, biosensors and medical substrates. With YES, customers ranging from startups to Fortune 100 companies can create and volume-produce products in a wide range of markets, including Advanced Packaging, MEMS, Augmented Reality/Virtual Reality and Life Sciences. YES is headquartered in the San Francisco Bay Area with offices in Livermore and Fremont, and a growing presence globally.
