  • Publication number: 20240136217
    Abstract: A manufacturing system includes a substrate disposed on a conveyer system. The conveyer system includes a pair of side supports. The substrate is moved on the conveyer system until the substrate is disposed over a bottom support block. The bottom support block is raised to physically contact the substrate. A transfer arm module is provided. The transfer arm module includes a flat bottom surface and an opening formed in the flat bottom surface. The transfer arm module is disposed with the flat bottom surface physically contacting the substrate opposite the bottom support block. A vacuum is enabled through the opening of the transfer arm module. The substrate is lifted off the bottom support block using the vacuum. The substrate is moved over a printing pallet using the transfer arm module. The vacuum is disabled when the substrate is in a positioning area of the printing pallet.

  • Patent number: 11945004
    Abstract: A semiconductor manufacturing equipment cleaning system has a multi-station cleaning and inspection system. Within semiconductor manufacturing equipment cleaning system, a tray cleaning station uses a first rotating brush passing over a first surface of a carrier and possibly semiconductor die, and a second rotating brush passing over a second surface of the carrier and semiconductor die opposite the first surface of the carrier and semiconductor die. Debris and contaminants dislodged from the first surface and second surface of the carrier by the first rotating brush and second rotating brush are removed under vacuum suction. A conveyor transports the carrier through the multi-station cleaning and inspection system. The first rotating brush and second rotating brush move in tandem across the first surface and second surface of the carrier. Air pressure is injected across the first rotating brush and second rotating brush to further remove debris and contaminants.
