  • Patent number: 9917170
    Abstract: A method of forming a contact structure includes providing a silicon-carbide substrate having a highly doped silicon-carbide contact region formed in the substrate and extending to a main surface of the substrate. A carbon-based contact region is formed which is in direct contact with the highly doped silicon-carbide contact region and which extends to the main surface. A conductor is formed on the carbon-based contact region such that the carbon-based contact region is interposed between the conductor and the highly doped silicon-carbide contact region. A thermal budget for forming the carbon-based contact region is maintained below a level that induces metal silicidization of the highly doped silicon-carbide contact region.

  • Patent number: 9768273
    Abstract: In one aspect, a method of forming a trench in a semiconductor material includes forming a first dielectric layer on a semiconductor substrate. The first dielectric layer includes first openings. An epitaxial layer is grown on the semiconductor substrate by an epitaxial lateral overgrowth process. The first openings are filled by the epitaxial layer and the epitaxial layer is grown onto adjacent portions of the first dielectric layer so that part of the first dielectric layer is uncovered by the epitaxial layer and a gap forms between opposing sidewalls of the epitaxial layer over the part of the first dielectric layer that is uncovered by the epitaxial layer. The gap defines a first trench in the epitaxial layer that extends to the first dielectric layer.

  • Publication number: 20170011927
    Abstract: A method for depositing an insulating layer includes performing a primary deposition over a sidewall of a feature by depositing a layer of silicate glass using a silicon source at a first flow rate and a dopant source at a second flow rate. A ratio of the flow of the dopant source to the flow of the silicon source is a first ratio. The method further includes performing a secondary deposition over the sidewall of a feature by increasing the flow of the silicon source relative to the flow of the dopant source. The ratio of the flow of the dopant source to the flow of the silicon source is a second ratio lower than the first ratio, and stopping the flow of the silicon source after performing the secondary deposition. A reflow process is performed after stopping the flow. A variation in thickness of the layer of silicate glass over the sidewall of a feature after the reflow process is between 1% to 20%.
