  • Publication number: 20230381812
    Abstract: A method of selective deposition that includes disposing in a deposition chamber a patterned substrate of side-by-side areas of metal and dielectric. The deposition chamber is connected to a bubbler that contains an N-heterocyclic carbenes (NHC) precursor. By heating the bubbler, gaseous free NHC is generated which is pulsed into the deposition chamber, where the NHC selectively chemisorbs onto the metal surface. Annealing after deposition of NHC improves surface patterning by removing stray metal from the dielectric section.

  • Patent number: 5132524
    Abstract: An multi directional laser scanner apparatus has a frame along with a plurality of lasers removably mounted in circular fashion to the frame for producing a plurality of light beams. A multi-faceted rotating mirror assembly is rotatably mounted to the frame and rotated by an electric motor and is aligned with a plurality of laser output beams. A plurality of fixed mirrors are attached in pairs to the frame and positioned for reflecting the light energy of the laser beam being reflected by the rotatable mirror assembly in a pattern onto a coded surface and positioned for receiving reflected beams from the coded surface and than directing the reflected beams in a reverse path onto the rotating mirror assembly and back towards each laser. A mirror mounted adjacent the output of each laser reflects each returning laser beam onto a photocell mounted to the frame for receiving the reflected signals from the coded surface and the signals are processed to read the coded signals.

  • Patent number: 5012079
    Abstract: A rotatable bar code scanner mirror assembly includes a rotatable mirror support frame operatively coupled to an electric motor shaft for rotation with the motor shaft. A plurality of mirrors are attached to the rotatable mirror support frame with each mirror mounted to a frame in a different plane intersecting at least one other plane of a mirror mounted to the support frame. Each mirror is shaped to have a pair of generally flat offset portions, offset from each other, on opposite sides of a center axis and each offset portion is connected with a center mirror portion so that a return laser beam can be reflected off the offset portions and the outgoing laser beam reflected off the center portion so that the outgoing and return beams use the same scanner mirror assembly.
