Ideal for Production Lift-Off, Step-Coverage, and Dual-Sided Coating Applications

The Temscal FC-3800 enables rapid processing of 150mm diameter wafers for lift off and/or step coverage applications. In each load, this load lock system can coat twenty-five 150mm diameter wafers for lift off or thirty-six 150mm wafers for step coverage. The 38″ x 38″ x 28″ product chamber is pumped by a high throughput 16″ cryopump. During wafer exchanges, the source chamber is maintained at high vacuum by the independent pumping of a dedicated 10″ cryopump.

Convenient Maintenance

The offset pumping port, the hinged door panels, and the swingout source tray are high-value maintenance features in Temescal systems. The offset pumping design reduces unscheduled downtime by minimizing the possibility of debris entering the pumping module. The hinged door panels open to the pumping system and the vacuum chamber. The electric hoist and the swing-out source tray facilitate access for evaporant reloading, cleaning, and maintenance. Access to the water manifold, the bellows-sealed high-vacuum valve, and other pumping system components is also simple and direct.

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.

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.
