Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: providing a workpiece; forming a protective material over a bottom surface and edges of the workpiece, wherein forming the protective material comprises forming a mask over the bottom surface, a top surface, and the edges of the workpiece, removing the mask from the edges and the bottom surface of the workpiece, forming the protective material over the bottom surface and the edges of the workpiece, and removing the mask from the top surface of the workpiece; and processing the top surface of the workpiece, wherein processing the top surface of the workpiece comprises epitaxially growing a material, and wherein the protective material protects the edges and the bottom surface of the workpiece during the processing of the top surface of the workpiece by preventing the epitaxially grown material from forming on the edges and the bottom surface of the workpiece.
