Application: Farbrication method (Patent ID: US20240107897A1)
The patent filed by Microsoft describes a fabrication method that involves forming a mask of amorphous material over a crystalline surface of a substrate to define areas for active devices and non-active regions. A deposition material is then formed through the mask using an epitaxial growth process, with reservoirs in the non-active region also being filled during this process. The method is particularly useful for creating quantum devices and involves the use of semiconductors and superconducting materials.
The claims associated with the patent detail the specific steps and materials involved in the fabrication method, including the use of selective area growth processes, metal sowed SAG processes, and various types of semiconductors. The patent also covers the formation of quantum computing devices, such as those utilizing Majorana Zero Modes, and the application of superconducting materials. Additionally, the patent extends to devices created using this fabrication method, highlighting the incorporation of quantum devices, electrical contacts, and various materials like semiconductors and superconductors. Overall, the patent focuses on a method for creating advanced electronic devices with a particular emphasis on quantum technology.
