  • Publication number: 20230253236
    Abstract: The present disclosure is related to a substrate processing apparatus. The substrate processing apparatus may include a chuck including a plurality of pin holes and a plurality of lift pins positioned to rise and fall through the plurality of pin holes. The substrate processing apparatus may include a lift plate configured to raise and lower the lift pins. The plurality of lift pins may include a lift pin having a rod shape configured to move up and down in a pin hole of the plurality of pin holes, a flexure coupled to a lower portion of the lift pin, a weight body positioned underneath the lift plate, and a weight string connecting the flexure and the weight body. The lift plate may include a string hole through which the weight string passes through.
