Publication number: 20230381812Abstract: 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.Type: ApplicationFiled: April 21, 2023Publication date: November 30, 2023Inventors: Cathleen M.

Patent number: 5132524Abstract: 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.Type: GrantFiled: May 21, 1990Date of Patent: July 21, 1992Assignee: LazerData CorporationInventors: Ishwar Singh, William Senkevich, William C.
