Title: Semiconductor device
Inventor: YAGUCHI AKIHIRO
IPC: H01L25/07
Filed: 2000-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device, in which thinning of the device is dealt with by making electrical connections through wire bonding, and stacked semiconductor elements are protected against damages due to temperature variations, and the like. SOLUTION: A semiconductor element mounted on the substrate side is made thicker than upper layer semiconductor elements. A rewiring layer is formed in at least one of stacked semiconductor elements. Since an underlying semiconductor element is made thicker than overlying elements, deformation of the underlying semiconductor element due to a load, e.g. temperature variation, is reduced, thus also reducing stress. The semiconductor device is made thin, by decreasing the number of bonding wires.
