    摘要: In one aspect of the present invention, a degradation assembly comprises an inverted conical face formed in a top end of a metal body tapering towards a central axis of the metal body. A base end of a carbide bolster is adapted to be brazed to the top end of the metal body within the inverted conical face. At least one protrusion is formed in the inverted conical face and is adapted to control a braze thickness between the face and the base end.

    摘要: Methods are provided of fabricating compound nitride semiconductor structures. A group-III precursor and a nitrogen precursor are flowed into a processing chamber to deposit a first layer over a surface of a first substrate with a thermal chemical-vapor-deposition process. A second layer is deposited over a surface of a second substrate with the thermal chemical-vapor-deposition process using the first group-III precursor and the first nitrogen precursor. The first and second substrates are different outer substrates of a plurality of stacked substrates disposed within the processing chamber as a stack so that the first and second layers are deposited on opposite sides of the stack. Deposition of the first layer and deposition of the second layer are performed simultaneously.

    摘要: Nitride optoelectronic devices that have asymmetric double-sided structures and methods fabricating such structures are disclosed. Two n-type III-N layers are formed simultaneously over opposite sides of a substrate with substantially the same composition. Thereafter, a p-type III-N active layer is formed over one of the n-type III-N layers but not over the other.

    摘要: Methods and systems permit fabricating structures using liquid sources without active temperature control. A substrate is disposed within a substrate processing chamber. A liquid source of a group-III precursor is provided in a bubbler. A push gas is applied to the liquid source to drive the group-III precursor into a vaporizer. A carrier gas is flowed into the vaporizer. A flow of vaporized group-III precursor carried by the carrier gas is injected from the vaporizer into the processing chamber. A nitrogen precursor is flowed into the processing chamber. A group-III nitride layer is deposited over the substrate with a thermal chemical vapor deposition within the processing chamber using the vaporized group-III precursor and the nitrogen precursor.
