SEMICONDUCTOR DEVICE

摘要

A semiconductor device includes a semiconductor substrate and a first electrode. An element region, and a non-element region that surrounds this element region, are formed on the semiconductor substrate. The first electrode is arranged on the semiconductor substrate and is electrically connected to the element region formed on the semiconductor substrate. The first electrode is made of at least two materials having different moduli of elasticity. A modulus of elasticity per unit area of an outer peripheral portion of the first electrode when the semiconductor substrate is viewed from above is smaller than a modulus of elasticity per unit area of a center portion of the first electrode.
