1. A method of manufacturing semiconductor devices, comprising:
- preparing a common substrate plate having opposing first and second main surfaces and being formed of an insulating material, a plurality of mounting areas being provided at said first main surface, each of said mounting areas being provided with an island section for mounting a semiconductor chip and electrode sections for connecting electrodes of the semiconductor chip, said second main surface being provided with a plurality of external connecting electrodes connected to said island sections and said electrode sections, respectively;
fixing a semiconductor chip on each of said island sections;
fixing a common cover member over said mounting areas so that said semiconductor chips are respectively disposed in hermetically sealed hollow spaces defined between said cover member and said common substrate plate; and
cutting through said common substrate plate and said common cover member to separate said common substrate plate and said common cover member into plural semiconductor devices having said semiconductor chips disposed in said hermetically sealed hollow spaces, respectively, between individual substrate plates and individual cover members, respectively.

Abstract
A method of manufacturing individual semiconductor devices by forming island sections 26 on the surface of a common substrate 21, forming electrodes 27 and 28 one on either side of each island section 26, die bonding a semiconductor chip 29 to each island section 26, and wire bonding the electrodes 27 and 28 to the semiconductor chip 29. A single common cover 36 is fixed over the entire surface of the common substrate 21 to form a hermetically sealed hollow space over each chip mounting section 41. The cover 36 and substrate 21 are separated at each mounting section 41 to form individual semiconductor devices.
