Abstract:
A method for forming a matrix composite layer on a workpiece and a workpiece with a matrix composite layer are disclosed. In an embodiment the method includes forming a wall around a metallic surface such that the wall extends in a vertical direction from a plane formed by the metallic surface, and depositing a filler material in a walled area on the metallic surface. The method further includes depositing a plastic material on the filler material and performing a vacuum treatment of the filler material and the plastic material thereby forming a matrix composite layer disposed on the metallic surface.
Abstract:
In various embodiments, an assembly for handling a semiconductor die is provided. The assembly may include a carrier with a surface. The assembly may also include an adhesive tape fixed to the surface of the carrier. The adhesive tape may be configured to adhere to the semiconductor die.
