Abstract:
A semiconductor device, comprising:a semiconductor chip having a main surface and an opposite surface which is opposite to the main surface, and including a semiconductor integrated circuit which is formed in the main surface, wherein the semiconductor chip has a thickness of less than 200 &mgr;m; a plurality of conductive layers which are vertically formed on the main surface of the semiconductor chip, the conductive layers being electrically connected to the semiconductor integrated circuit; a first sealing resin which seals the main surface of the semiconductor chip, with edges of the conductive layers being exposed through the first sealing resin; and a second sealing resin which seals the opposite surface; wherein the semiconductor device satisfies a relation as follows: 0.2&lE;y/x<1, where x denotes a thickness of the first sealing resin, and y denotes a thickness of the second sealing resin.
