  • Publication number: 20240160117
    Abstract: Apparatus and method for substrate processing are described herein. More specifically, the apparatus and method are directed towards apparatus and method for performing a field guided post exposure bake operation on a semiconductor substrate. The apparatus is a processing module (100) and includes an upper portion (102) with an electrode (400) and a base portion (104) which is configured to support a substrate (500) on a substrate support surface (159). The upper portion (102) and the base portion (104) are actuated toward and away from one another using one or more arms (112) and form a process volume (404). The process volume (404) is filled with a process fluid and the processing module (100) is rotated about an axis (A). An electric field is applied to the substrate (500) by the electrode (400) before the process fluid is drained from the process volume (404).

  • Patent number: 11609505
    Abstract: Embodiments of the present disclosure generally relate to apparatus and methods for verification and re-use of process fluids. The apparatus generally includes a tool for performing lithography, and a recirculation path coupled to the tool. The recirculation path generally includes a collection unit coupled at first end to a first end of the tool, and a probe coupled at a first end to a second end of the collection unit, the probe for determining one or more characteristics of a fluid flowing from the tool. The recirculation path of the apparatus further generally includes a purification unit coupled at a first end to a third end of the collection unit, the purification unit further coupled at a second end to a second end of the probe, the purification unit for changing a characteristic of the fluid.

  • Patent number: 11555730
    Abstract: A method and apparatus for determining particle contamination of a process fluid is disclosed herein. In one example, a fluid resistivity measurement probe is provided. The system includes an upstream fluid conduit, a downstream fluid conduit, and a measuring section. The measuring section has a metal rod, and a ground electrode. The ground electrode surrounds and is coaxial with the metal rod. The upstream fluid conduit is coupled to a first end of the ground electrode. The downstream fluid conduit is coupled to a second end of the ground electrode. The metal rod and the ground electrode define a space therebetween. The space flows a fluid from the upstream fluid conduit to the downstream fluid conduit.

  • Patent number: 6188520
    Abstract: A polarizer is made from pairs of polarizing beam splitting cubes. In every pair, a first cube transmits P-polarized light and reflects S-polarized light. A retarder rotates the transmitted light to become S-polarized. A second cube receives only the reflected light, and redirects it in the direction of the transmitted light. A polarizing filter filters the reflected light, but not the rotated light. Exposing the retarder improves the transmission throughput of the overall polarizer. A stop at the side of the second cube blocks light from entering the first cube of an adjacent pair.
