Patent number: 11901476Abstract: The present invention utilizes epitaxial lift-off in which a sacrificial layer is included in the epitaxial growth between the substrate and a thin film III-V compound solar cell. To provide support for the thin film III-V compound solar cell in absence of the substrate, a backing layer is applied to a surface of the thin film III-V compound solar cell before it is separated from the substrate. To separate the thin film III-V compound solar cell from the substrate, the sacrificial layer is removed as part of the epitaxial lift-off. Once the substrate is separated from the thin film III-V compound solar cell, the substrate may then be reused in the formation of another thin film III-V compound solar cell.Type: GrantFiled: February 8, 2021Date of Patent: February 13, 2024Assignee: MICROLINK DEVICES, INC.Inventors: Noren Pan, Glen Hillier, Duy Phach Vu, Rao Tatavarti, Christopher Youtsey, David McCallum, Genevieve Martin

Patent number: 8912631Abstract: A heterojunction bipolar transistor (HBT) is provided with an improved on-state breakdown voltage VCE. The improvement of the on-state breakdown voltage for the HBT improves the output power characteristics of the HBT and the ability of the HBT to withstand large impedance mismatch (large VSWR). The improvement in the on-state breakdown voltage is related to the suppression of high electric fields adjacent a junction of a collector layer and a sub-collector layer forming a collector region of the HBT.Type: GrantFiled: March 1, 2011Date of Patent: December 16, 2014Assignee: MicroLink Devices, Inc.Inventors: Noren Pan, Andree Wibowo

Patent number: 8450162Abstract: Methods and systems for fabricating an integrated BiFET using two separate growth procedures are disclosed. Performance of the method fabricates the FET portion of the BiFET in a first fabrication environment. Performance of the method fabricates the HBT portion of the BiFET in a second fabrication environment. By separating the fabrication of the FET portion and the HBT portion in two or more separate reactors, the optimum device performance can be achieved for both devices.Type: GrantFiled: April 5, 2011Date of Patent: May 28, 2013Assignee: MicroLink Devices, Inc.Inventors: Noren Pan, Andree Wibowo
