  • Patent number: 12235582
    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: 20240395582
    Abstract: A method of controlling a feedback control system of a semiconductor process chemical fluid in a storage tank includes performing a fluid quality measurement of fluid by a spectrum analyzer positioned adjacent to a dispensing port of the storage tank, and determining whether a variation in fluid quality measurement of the fluid is within an acceptable range. The method further includes in response to a variation in fluid quality measurement that is not within the acceptable range of variation in fluid quality measurement, automatically adjusting a configurable parameter of the semiconductor process chemical fluid in the storage tank to set the variation in fluid quality measurement of the fluid within the acceptable range.
