  • SYSTEMS AND APPARATUS FOR CONTROLLING FLUID FLOW
    Publication number: 20250132170
    Abstract: Systems for processing articles are essential for semiconductor fabrication. These systems employ a variety of apparatuses for controlling flow. In one implementation, an apparatus for controlling flow may utilize a body having a flow path extending from an inlet to an outlet. A valve, a flow restrictor, and a pressure sensor are operably coupled to the flow path. The valve incorporates first and second actuators which enable control of mass flow rates of fluid flowing through the flow path.

  • METHOD OF MANUFACTURING SEMICONDUCTORS USING FLUID DELIVERY SYSTEM
    Publication number: 20240274444
    Abstract: A method of manufacturing a substrate block for a fluid delivery system is disclosed. First, a mold is provided, the mold having a cavity. The cavity of the mold is filled with a fluoropolymer to form a substrate block having an upper surface. A curved insert is withdrawn from the cavity to form a substrate fluid passageway extending from an inlet substrate port to an outlet substrate port. The substrate fluid passageway extends between the inlet substrate port and the outlet substrate port in a smooth arc free of corners or angular walls.

  • FLUID DISPENSING SYSTEM
    Publication number: 20070205230
    Abstract: A fluid dispensing system includes a container, a pump assembly and a bleed valve. The pump assembly is connected to the container selectively pressurizing the container and includes an outlet port. The outlet port has a check valve precluding flow from the container through the outlet port. The bleed valve is in communication with an aperture formed through the container. The bleed valve relieves excess pressure in the container.

  • Fluid dispensing system
    Publication number: 20070175928
    Abstract: A fluid dispensing system includes a pump assembly for pressurizing a low cost container, the container non reversibly connected to a coupler module. A wand assembly is releasably connected to the coupler module. A discharge conduit fluidly connects the wand assembly to the container to displace a check valve in the pump assembly to permit flow from the pump assembly. The wand assembly includes a grip body slideable relative to the discharge conduit between a retracted storage position and an extended operable position.
