Abstract

A semiconductor device comprises a semiconductor chip having a rear surface provided with an uneven structure having a preselected pattern and comprised of concave and convex portions. The preselected pattern of the uneven structure is tilted so as to be in parallel to a crystal orientation of <110> of the semiconductor chip. An electrode is disposed on the concave and convex portions of the uneven structure.
