Abstract
A semiconductor device of the invention includes: a substrate having a hollowed hollow section on a top surface; a semiconductor chip mounted in the hollow section of the substrate; and a lid having a substantially plate-shaped top plate section that opposes the substrate and covers the hollow section, and having at least one pair of side wall sections that project from a circumference of the top plate section towards the substrate and that engage with a side surface of the substrate. The substrate and the lid can be accurately positioned.
