Abstract

PURPOSE: The 1st element group is formed from the surface of a semiconductor substrate, and the 2nd element group from its reverse surface to make the degree of the thermal expansion on both the top and reverse surfaces of the substrate uniform and to prevent its curvature, thereby improving its yielding.
