Patent ID: 7893540

Claim:
A semiconductor device comprising: a first chip; a plurality of first internal electrodes disposed on a first surface of the first chip; a plurality of second internal electrodes disposed on a second surface opposite to the first surface of the first chip, the second internal electrodes being arranged in a first pitch; a plurality of third internal electrodes disposed on the second surface of the first chip, the third internal electrodes being arranged in a second pitch which is larger than the first pitch; a plurality of first through electrodes disposed to penetrate the first chip, each of the first through electrodes connecting electrically between one of the first internal electrodes and an associated one of the second internal electrodes; a plurality of second through electrodes disposed to penetrate the first chip, each of the second through electrodes connecting electrically between one of the first internal electrodes and an associated one of the third internal electrodes; a second chip that is directly mounted over the first surface of the first chip and has a plurality of internal terminals connected respectively to the first internal electrodes of the first chip; and a third chip that is directly mounted over the second surface of the first chip and has a plurality of internal terminals connected respectively to the second internal electrodes of the first chip, wherein the internal terminals of the second chip include a set of first terminals and a set of second terminals, each of the first terminals being connected to associated one of the second internal electrodes by the first through electrodes, and each of the second terminals being connected to associated one of the third internal electrodes by the second through electrodes.
