  • Publication number: 20240105496
    Abstract: The present invention provides a substrate supporting apparatus having a spin chuck and a plurality of locating pins. The spin chuck configured to support and rotate a substrate has a supporting surface. The locating pins are disposed at the periphery of the supporting surface for limiting the substrate horizontal displacement. The supporting surface defines a first annular region. The first annular region is divided into a plurality of pin regions and a plurality of non-pin regions. The pin regions and the non-pin regions are arranged alternatively in a circumferential direction of the first annular region. Each of the pin regions is corresponding to one locating pin. A plurality of Bernoulli holes are set in the first annular region and is configured as an uneven structure in the first annular region so as to supply stronger gas flow in the pin regions than in the non-pin regions.
