Profile: EpiTek Incorporated specializes in offering metal organic chemical vapor deposition (MOCVD) system upgrades, preventative maintenance, production support, and parts sourcing services. Our metal organic chemical vapor deposition (MOCVD) system relies on the process control hardware and software running at peak performance. Aging process control software or malfunctioning hardware can no longer operate efficiently with technologically advanced MOCVD equipment. Our process control hardware and software is to avoid continued or future production delays. EpiControl software is a Windows based real time user-friendly interactive process control system for MOCVD and CVD applications. This software utilizes spreadsheet run format that includes sequential layer operation defined by time steps, ramping, and looping functions.
