Semiconductors having defect denuded zones |
摘要 |
A method for processing a semiconductor substrate to form a denuded zone therein. The method includes providing a semiconductor substrate having an oxygen concentration in a region of the substrate adjacent to a surface of such substrate. A trench is formed in the surface of the substrate. Subsequent to the formation of the trench, reducing the oxygen concentration within the region.
