Biomedical

Yield Engineering Systems (YES) builds process control equipment to serve the needs of the biotech industry. 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).
