  • Publication number: 20220299876
    Abstract: A developer tool described herein includes a dispenser that includes a greater quantity of nozzles in a central portion relative to a perimeter portion such that the developer tool is capable of more effectively removing material from a photoresist layer near a center of a substrate (which tends to be thicker near the center of the substrate relative to the edge or perimeter of the substrate). In this way, the developer tool may reduce the amount of photoresist residue or scum remaining on the substrate near the center of the substrate after a development operation, which may enable defect removal and/or prevention, may increase semiconductor processing yield, and/or may increase semiconductor processing quality.

  • Publication number: 20210202284
    Abstract: A lithography includes a storage tank that stores process chemical fluid, an anti-collision frame, and an integrated sensor assembly. The storage tank includes a dispensing port positioned at a lowest part of the storage tank in a gravity direction. The anti-collision frame is coupled to the storage tank. An integrated sensor assembly is disposed on at least one of the anti-collision frame and the storage tank to measure a variation in fluid quality in response to fluid quality measurement of fluid.

  • Patent number: 10234548
    Abstract: The present invention is directed to an ultrasonic detection device and detection method thereof. The ultrasonic detection device includes a processor and a transceiver module, whereby the transceiver module may be operated to enter an additional reception mode and receive a first ambient echo. The processor may analyze the first ambient echo and generate an analysis result. When the generated analysis result shows that the first ambient echo has a signal characteristic indicative of an interference source in the environment, the transceiver module may again enter the additional reception mode before a detection operation is performed. As a result, an elimination mode may be performed to correctly obtain or distinguish the corresponding reflected wave of the detection operation, thereby avoiding an error of operation, such as distance detection, due to the presence of an interference source.
