Electrostatic Chuck Optimizer
Model 640 - TREK, INC. (TREK)
Trek’s Model 640 Electrostatic Chuck Optimizer system is a diagnostic tool which enables evaluation and optimization of waveforms/voltages for electrostatic chucks/clamps in order to minimize de-clamp time, maximize clamp force, and achieve optimum wafer processing for ESC systems.
Model 640 combines two amplifiers (for two-phase voltage combinations) and a waveform generator, which can be independently programmed and configured to investigate, research, and discover the perfect power supply and waveform recipe to efficiently drive an ESC application. An electrostatic voltmeter (ESVM) is included to monitor residual voltage from the clamping/de-clamping process.
