  • Patent number: 10971354
    Abstract: Methods of drying a semiconductor substrate may include applying a drying agent to a semiconductor substrate, where the drying agent wets the semiconductor substrate. The methods may include heating a chamber housing the semiconductor substrate to a temperature above an atmospheric pressure boiling point of the drying agent until a vapor-liquid equilibrium of the drying agent within the chamber has been reached. The methods may further include venting the chamber, where the venting vaporizes the liquid phase of the drying agent from the semiconductor substrate.

  • Patent number: 10191379
    Abstract: In systems and methods for removing a photoresist film off of a wafer, the wafer is moved into a bath of a process liquid in a process tank. The process liquid removes the photoresist film from the wafer. The process liquid is pumped from the process tank to a filter assembly and moved through filter media to filter out solids from the process liquid, and the filtered process liquid is returned to the process tank. A scraper scrapes the filter media to prevent clogging of the filter media by accumulated solids.

  • Publication number: 20170263472
    Abstract: A wafer processor has a rotor holding wafers within a process tank. The rotor rotates sequentially moving the wafers through a process liquid held in the process tank. The tank may have an I-beam shape to reduce the volume of process liquid. A load port is provided at a top of the process tank for loading and unloading wafers into and out of the process tank. Rinsing and cleaning chambers may be associated with the load port to remove process liquid from processed wafers. The processor may be oriented with the rotor rotating about a horizontal axis or about a vertical axis.

  • Patent number: 5489506
    Abstract: A method and apparatus for continuously sorting living cells from a mixture of many unlike cells to obtain separate populations of like cells. The invention comprises cell and fluid intake ports, a cell deflection chamber, and a series of output vacuum pumps attached to a like number of collection reservoirs. The cell intake section is a two-stage system that first mixes the incoming cells with a deionized, buffered, processing medium then sheathes the output stream with a centering carrier fluid. An expansion chamber contains one or more electrodes connected to one or more RF generators that act upon the passing cells so that they are fanned out within the expansion chamber according to their size, physical construction, chemical composition and electronic properties. Vacuum pumps draw the fluids through the system and deposit the sorted cells in separate reservoirs.
