发明名称 半導体装置および基板
摘要 A semiconductor apparatus includes a semiconductor substrate having a main surface, a multilayer structure circuit formed over the main surface of the semiconductor substrate, a protective wall formed in the same layer as an uppermost layer of the multilayer structure circuit so as to surround the multilayer structure circuit in plan view, and an alignment mark formed in the same layer as the uppermost layer. The alignment mark is formed so as to contact at least part of the protective wall.
