Abstract

A semiconductor device module is provided that prevents adhesion defects from causing in bonding a semiconductor sensor chip to a sensor stage with an adhesive and improving the reliability thereof. The semiconductor device module includes a sensor stage and a semiconductor optical sensor chip mounted on the sensor stage. The sensor stage includes a U-groove formed in an upper central surface portion of a bottom wall thereof. The sensor chip is bonded to the sensor stage with a thermosetting and UV-curing adhesive coated in the U-groove. The U-groove, includes an island-shaped flat pedestal located at a central bottom portion of the U-groove for mounting the sensor chip thereon. Pins are preferably disposed on both sides of the pedestal to hold the sensor chip horizontally, and the side walls of the U-groove 3b are preferably slanted such that the adhesive coated in the U-groove is prevented from splashing to the outside.
