The Tempress Low Pressure Chemical Vapor Deposition (LPCVD) system is a modular horizontal furnace designed to process substrates up to 150mm in diameter as part of the semiconductor, optical, MEMS, and solar device manufacturing. It is a 4-stack system set up to deposit silicon nitride, polysilicon, low temperatrue oxide (LTO), silicon rich oxide (SRO), phosphorus doped LTO, and phosphorus doped polysilicon. All tubes operate independently.
