  • Patent number: 10651034
    Abstract: A method of forming an epitaxial layer on a substrate such as a sapphire wafer that does not readily absorb thermal radiation. The method includes coating a first side surface of the substrate with an energy-absorbing opaque material. The opaque material forms a thermally absorptive coating on the substrate. The coated substrate may be heated to remove contaminants from the thermally absorptive coating. The coated substrate is positioned in a vacuum deposition chamber and heated by directing radiative energy onto the thermally absorptive coating. An epitaxial layer such as GaN or SiGe is formed on a second side surface of the substrate opposite the thermally absorptive coating.

  • Patent number: 10236181
    Abstract: A manufacturing system and a method for forming a clean interface between a functional layer and a 2D layered semiconductor are provided herein. In the steps of the method, the substrate equipped with the 2D layered semiconductor is exposed to a reaction gas, and a stimulus is applied to the reaction gas to generate active particles having higher selectivity toward contaminants on the exposed surface of the 2D layered semiconductor so that the contaminants can be decomposed and removed. Additionally, the contaminants can be removed without damage to the 2D layered semiconductor. A functional layer is in-situ deposited to be in contact with the 2D layered semiconductor. Without the contaminants, a clean interface between the functional layer and the 2D layered semiconductor can be obtained and the 2D layered semiconductor can exhibit better electrical properties.
