Latest Patents

Van Bilsen's latest patents include a self-centering wafer support system and a low mass wafer support system. The self-centering wafer support system introduces improvements in the design of a low mass wafer holder. These improvements feature peripherally located, integral lips that space a wafer or other substrate above the base plate of the wafer holder. This design creates a uniform gap between the wafer and the base plate, which helps temper rapid heat exchanges and allows gas to flow between the wafer and wafer holder during pick-up. Additionally, it reduces thermal disturbance from lip contact with the wafer. The gas flow during pick-up can be facilitated through radial channels in the upper surface of the wafer holder or through backside gas passages. A thicker ring is also incorporated at the perimeter of the wafer holder to accommodate stresses from thermal gradients.
