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.
Key features:
- Large capacity: 25 x 150mm
- 40% more wafers with no increase in footprint or power consumption

Temescal Control System
The Temescal Control System (TCS) provides fully integrated, recipe-driven process and vacuum control. Operating in any of three password-protected modes, the TCS also offers process variable monitoring, process and historical trend tracking, and process data logging.
TCS System Map During Deposition
The TCS Automatic Mode
Auto Mode operation provides fully automated execution of user-programmed recipes consisting of up to twenty process steps, as well as full abort diagnostics. The TCS Auto Mode also offers independent autopump and autovent operations, automated cryopump regeneration, and automated rate-of-rise testing.
Manual Mode Operation
The TCS Manual Mode enables the user to set process parameters, operate major components and subsystems individually with full interlock protection, and execute nonautomated single-film deposition processes.
Service Mode Operation
The TCS Service Mode provides noninterlocked low-level control over any of the system’s valves, pumps, motors, or power supplies.
