Horizontal LPCVD Furnace

for High Process Performance

The design of the SVCS Low Pressure Chemical Vapor Deposition furnaces combines the multiple process capability with the needs of a maximum capacity for full production system (SVcFUR-FP) and high flexibility small scale versions for use in research and pilot production (SVcFUR-RD). It provides an easy-to-maintain, safe and reliable horizontal furnace platform.

The SVCS design is outstanding for high efficiency, minimised footprint and low cost of ownership while offering high process flexibility.
