  • Patent number: 11226551
    Abstract: The present disclosure provides a mask for photolithography patterning. The mask includes a substrate, a pattern layer on a surface of the substrate. The mask also includes a pellicle attached to the substrate and configured to isolate the pattern layer from ambient. The pellicle includes a membrane between the pattern layer and ambient, a frame for securing the membrane on the substrate, and an optical member disposed in the membrane. A method for manufacturing the mask is also provided.
    Type: Grant

  • Patent number: 10969682
    Abstract: An apparatus includes a developing tank, and the developing tank has a sidewall and a bottom. A fluid manifold is adjacent the bottom of the developing tank. The fluid manifold includes a plurality of holes and a plurality of valves. Developer and rinsing fluid flow through the plurality of holes. Each of the plurality of the valves corresponds to a different hole of the plurality of holes, and the plurality of valves allow the developer and the rinsing fluid to flow through the holes when open and prevent the developer and the flowing liquid from flowing through the holes when closed. The developer flows through a developer inlet to the fluid manifold. The rinsing fluid flows through a rinsing fluid inlet to the fluid manifold. A controller is configured to individually control opening and closing of each of the plurality of valves.

  • Patent number: 10698313
    Abstract: An apparatus includes a developing tank and a fluid manifold in the bottom of the developing tank. The fluid manifold includes a plurality of holes through which developer flows and a plurality of valves corresponding to the plurality of holes. The valves allow developer to flow through the holes when open and prevent developer from flowing through the holes when closed. A trench surrounds the fluid manifold through which developer is drained from the developing tank. A controller is configured to control opening and closing of the valves. In an embodiment, the apparatus includes a clamping mechanism configured to insert the substrate into and remove the substrate from the developing tank.
