Temescal UEFC-5700 Deposition System with Auratus

Ultimate Throughtput in Lift-Off Processes with 150mm or 200mm Wafers

The Temescal UEFC-5700 with Auratus represents our ultimate high-throughput platform for lift-off oriented evaporation. This system is designed to support the metallization of forty-two 150mm wafers per load via high capacity e-beam evaporation.

The load locked product chamber can be pumped by as many as two dedicated, high throughput 16-inch cryogenic pumps. Dual-cryopumps make it possible to pump this large chamber in 10 minutes from atmosphere to pressures in the range of 10E-7. During wafer exchanges, the source chamber is maintained at high vacuum by the independent pumping of a dedicated 10-inch cryopump.
