Abstract
Abstract At least one part of a two-part container of a portable semiconductor device has an electronic part accommodating portion, a foamed resin accommodating portion provided at a peripheral edge portion of the container for accommodating an excess of foamed resin, and a coupling groove for coupling the electronic part accommodating portion to the foamed resin accommodating portion. Since the electronic parts and a circuit board are completely embedded in the device, a semiconductor device exhibiting excellent resistance to environment can be manufactured by a simple process.
