Semiconductor Manufacturer Orders Crystal-Growing Furnaces
Thermcraft Inc. received an order for multiple crystal-growing furnace systems from a manufacturer of communications semiconductor devices. The systems will be used for LPE crystal growth and will feature fully automated PLC-based control systems. Each system is built around a vertical tube furnace that uses heavy-gauge resistance wire for its heating element and a serpentine water jacket for liquid cooling. All furnace movements, liquid cooling and temperature-profile programming are centrally controlled through the PLC. The entire system is packaged within a fully powder-coated, fabricated cabinet assembly.
