Temescal UEFC-4900 Deposition System with Auratus

Ultimate Uniformity in Lift-Off Processes, Optimized for 150mm Wafers

The Temescal UEFC-4900 with Auratus is the compact version of the UEFC-5700. It represents the ultimate mid-sized coater for lift-off processes. The source-to-substrate distance and chamber angles in the UEFC-4900 have been optimized for 150mm wafers and the system supports 25 x 150mm wafers.

The load locked product chamber is pumped by a CTI model CT-500 cryogenic pump. Powerful cryopumps make it possible to pump this large chamber in 15 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.
