is a wet bench manufacturer and global supplier of wet process equipment to the semiconductor, MEMS, photonics, solar cell, RFID, disc drive and flat panel display manufacturing industries since 1983.
About Wafer Process Systems
Wafer Process Systems Inc. is a wet bench manufacturer which was established in March of 1983 by current President and CEO Douglas H. Caldwell. The company was created out of the necessity to satisfy the industry needs for reputable in field service on wet benches and general wet process equipment support. The company originated mainly as a service and support organization for local Silicon Valley customers. As its customer base grew and their need for wet bench service, wet bench modifications driven by process changes as well as new wet bench requirements, Wafer Process Systems Inc. established a full time in house engineering and manufacturing team to support these needs.
Mr. Caldwell started the company after a four year tenure with Semifab Inc. where he was responsible for customer service and equipment support for North America. His responsibilities involved equipment installations, startups, maintenance and in field modifications. At that time Semifab Inc. was one of the industry’s largest manufacturer of wet chemical process equipment and laminar flow hoods for the semiconductor and biomedical industries. Prior to working at Semifab Inc. Mr. Caldwell worked for Microair, Inc. for a period of four years where his responsibilities ranged from manufacturing to final test and quality assurance. The exodus of Microair’s engineering manager and sales manager, who left to start Semifab Inc. was the driving force which lead Mr. Caldwell to join Semifab Inc.
After six months of operation Mr. Caldwell was joined by Mr. Christopher J. Schmitz who assumed the position of VP of Engineering. Prior to Mr. Schmitz joining Wafer Process Systems Inc. he too worked for Semifab Inc. in their engineering department for a period of three years where he was responsible for design and generating documentation for manufacturing. Prior to his tenure with Semifab Inc. he had been employed by Santa Clara Plastics Inc., currently known as SCP Global, for a period of three years in the engineering department where his responsibilities were generating production drawings used in the manufacturing of Wet Chemical Process Equipment.
