A METHOD OF MANUFACTURING A WAFER

摘要

The present invention relates to a method of manufacturing a semiconductor wafer that includes providing a substrate of a single crystalline first material that has an unfinished or rough surface, and epitaxially growing at least one layer of a second material directly on the unfinished or rough surface of the first material. The second material has a lattice that is different from that of the first material and the epitaxial growing of the second material is advantageously performed before a final surface finishing step on the unfinished or rough surface of the substrate to increase bonding between the materials.
