Abstract
According to the present invention, a gettering layer is deposited both on the side surfaces and the bottom surface of a semiconductor chip. The semiconductor chip is then mounted on the board of a package so that a Schottky barrier is formed on the bottom surface. With this structure, metal ions that pass through the board of the package can be captured by the defect layer deposited on the side surfaces and/or the bottom surface of the semiconductor chip, and by the Schottky barrier.
