  • Patent number: 5483106
    Abstract: In fixing a sensor element for sensing stress on a substrate by using an adhesive for semiconductors, the present invention aims to solve both the problems of stress applied from the substrate side due to temperature change and defects in wire bonding in the wire bonding process. In a semiconductor device equipped with a sensor element for sensing stress fixed on a substrate, an adhesive for semiconductors is used which is prepared by compounding resin beads made of resin with a base adhesive made of flexible resin.
