Wafer support pin lifting device for cavity
A recently granted patent (Publication Number: US11990363B2) discloses a wafer support pin lifting device designed for use in a cavity. The device comprises a support plate for holding multiple support pins, a slide block connected to the cavity's inner wall for sliding movement, and a lifting pole with three ends - one connected to the support plate, one pivotally connected to the slide block, and one connected to an actuator for controlling vertical movement. The pivotal connection between the lifting pole and the slide block allows for the adjustment of the support plate's orientation, ensuring it can be horizontal or tilted as needed.
Furthermore, the device includes features such as a slide track on the cavity's inner wall for the slide block's movement, a connection arm on the lifting pole for pivotal connection to the slide block, and springs for applying biasing forces to control the support plate's position. The support plate, along with a carrier plate for holding a wafer, allows for the adjustment of the support pins to ensure the wafer remains horizontal when the support plate is in a high position and tilted when in a low position, facilitating the handling and processing of wafers in a manufacturing environment.
