Publication number: 20220316063Abstract: RPCVD apparatus for forming a film is disclosed including a showerhead having at least one gas chamber, one or more plasma inlets to deliver plasma from one or more plasma generators into a reaction chamber; and a plurality of gas inlets to deliver gas from at least one gas chamber into the reaction chamber. At least one of the plasma inlets is located at a position that is between a central region and an outer region of the showerhead and off-centre from an axis of rotation. The plasma generators generate plasma in line of sight of the susceptor and the plasma inlets have openings that are larger than openings of the gas inlets. The gas inlets are configured such that a combination of all of the spatial distributions of gas from the gas inlets provides a uniform distribution of gas density on the surface of a susceptor between a central region and an outer region of the susceptor, for a full rotation of the susceptor.Type: ApplicationFiled: September 4, 2020Publication date: October 6, 2022Inventors: Joshua David Brown, Satyanarayan Barik, Stephen Richard O'Farrell, Ian Mann

Patent number: 11081618Abstract: Methods for fabricating semiconductor devices incorporating an activated p-(Al,In)GaN layer include exposing a p-(Al,In)GaN layer to a gaseous composition of H2 and/or NH3 under conditions that would otherwise passivate the p-(Al,In)GaN layer. The methods do not include subjecting the p-(Al,In)GaN layer to a separate activation step in a low hydrogen or hydrogen-free environment. The methods can be used to fabricate buried activated n/p-(Al,In)GaN tunnel junctions, which can be incorporated into electronic devices.Type: GrantFiled: December 23, 2019Date of Patent: August 3, 2021Assignee: Gallium Enterprises Pty LtdInventors: Ian Mann, Satyanarayan Barik, Joshua David Brown, Danyu Liu
