    摘要: An improved HE LINAC-based ion implantation system is disclosed utilizing direct digital synthesis (DDS) techniques to obtain precise frequency and phase control and automated electrode voltage phase calibration. The DDS controller may be used on a multi-stage linear accelerator based implanter to digitally synchronize the frequency and phase of the electric fields to each electrode within each stage of the accelerator. The DDS controller includes digital phase synthesis (DPS) circuits for modulating the phase of the electric field to the electrodes, and a master oscillator that uses digital frequency synthesis or DFS to digitally synthesize a master frequency and phase applied to each of the DPS circuits. Also disclosed are methods for automatically phase and amplitude calibrating the RF electrode voltages of the stages.

    摘要: Method and apparatus for use in setting up workpiece treatment or processing equipment. A disclosed system processes silicon wafers that are treated during processing steps in producing semiconductor integrated circuits. The processing equipment includes a wafer support that supports a wafer in a treatment region during wafer processing. A housing provides a controlled environment within the housing interior for processing the wafer on the wafer support. A mechanical transfer system transports wafers to and from the support. A wafer simulator is used to simulate wafer movement and includes a pressure sensor for monitoring contact between the simulator and the wafer transfer and support equipment. In one illustrated embodiment the wafer simulator is generally circular and includes three equally spaced pressure sensors for monitoring contact with wafer transport and support equipment.

    摘要: A finger grip has a resilient transparent tubular body which is adapted to be inserted into a finger hole of a bowling ball. The insert has a generally cylindrical inner wall surface with a pair of opposing gripping surfaces at each end of the insert. Thus, the insert provides four gripping members in a single insert.
