Liquid Phase Epitaxy (LPE) Reactor Growth Systems
The Liquid Phase Epitaxy (LPE) Reactor system provides the user with a process controlled furnace for automated user specified segment driven process recipes that provide optimum control over wafer processing and repetitive results from run to run. The overall system is designed to give the user reliability and repeatability for growing liquid phase epitaxial layers.
The LPE system is capable of processing a wafer over a uniform flat temperature zone. All system components are located on the side, top, or front of the furnace and either a left or right side glovebox.
An automatic, cantilevered, non-contact wafer loading system is incorporated for loading and unloading of the graphite process boat. The loading system consists of a quartz boat holder that is cantilevered from the automatic end cap assembly. The end cap assembly locates the process boat within the quartz condensation sleeve inside the quartz process tube. The translation speed of the loading system is adjustable from 50-300 mm/min. Door interlocks are provided to prevent startup of a process run in the event of an incomplete door closure.
CVD Equipment Corporation also offers a vertical dipping system for LPE growth of thicker films at higher rates, e.g. HgCdTe (MCT). It operates at pressures up to 200 PSIG and temperatures to 600 °C. The system has a load lock which can be evacuated to 10-6 Torr and pressurized to 200 PSIG.

powered by CVDWinPrC™
Operated through our CVDWinPrC™ process control software, the systems automatically log data and graphically show time-dependent values of user-selected parameters. CVDWinPrC™ also allows users to load preprogrammed recipes, modify, check and create new recipes, and view realtime or saved process data.
The systems have application configured safety protocols embedded into relay logic, PLC, and CVDWinPrC™ software.
The images shown are examples of many CVD systems we design and manufacture in-house for innovators working on next generation process and material development.
We have customers worldwide at universities, governmental labs, start-ups, and fortune 500 companies.
