SMI offers a user-friendly real time SmartCVD Interactive Process Control Industrial system for MOCVD. The system utilizes spreadsheet format run programming that includes sequential layer operation defined by time steps, ramping, and looping functions. Recipes are easily editable for efficient programming. Other features include a real-time mimic screen of all process components as the primary system operator interface for fully automated sequential layer by layer operation, maintenance routines, manual servicing operation, operator reconfigurable system parameters, process trend monitors, and safely/alarm capabilities. All run parameters are saveable and recallable for repeated use or simple editing for a subsequent run. The system uses an industrial computer and PLC Controller for maximum reliability. Importantly, this control system interfaces with all common in-situ process monitors (optical, RGA, and so on), offers remote access and is provided with training software.
