  • Patent number: 11892777
    Abstract: The present application relates to contact immersion lithography exposure units and methods of their use. An example contact exposure unit includes a container configured to contain a fluid material and a substrate disposed within the container. The substrate has a first surface and a second surface, and the substrate includes a photoresist material on at least the first surface. The contact exposure unit includes a photomask disposed within the container. The photomask is optically coupled to the photoresist material by way of a gap comprising the fluid material. The contact exposure unit also includes an inflatable balloon configured to be controllably inflated so as to apply a desired force to the second surface of the substrate to controllably adjust the gap between the photomask and the photoresist material.
    Type: Grant
