Abstract:
1. A semiconductor device, comprising: a rectangular lower semiconductor element; a first insulating film provided on a surface of the lower semiconductor element; a plurality of external electrodes located in a pattern on the first insulating film along sides thereof; a plurality of internal electrodes electrically connected to the plurality of external electrodes via a plurality of line patterns respectively and located in a pattern on the first insulating film; a second insulating film, being a thin film, having openings positionally corresponding to the plurality of internal electrodes and the plurality of external electrodes, and provided on the plurality of line patterns; dams provided in such a pattern that each of the dams encloses one or at least two external electrodes among the plurality of external electrodes; an upper semiconductor element mounted on the lower semiconductor element such that a plurality of terminals on the upper semiconductor element are electrically connected to the plurality of internal electrodes respectively; and a resin potted to flow to a space between the lower semiconductor element and the upper semiconductor element.
