Abstract
The present invention relates to a semiconductor device including: a first semiconductor element fixed onto an adherend by flip-chip connection; an adhesive layer for embedding a space between the adherend and the first semiconductor element and embedding the first semiconductor element; and a second semiconductor element connected to the first semiconductor element via the adhesive layer, wherein the adhesive layer has a predetermined melt viscosity and thixotropic index.
