Abstract:
A semiconductor device has a semiconductor chip adhesively bonded to a die pad. An area having large irregularities is formed on an upper side surface of the semiconductor chip to be covered by an encapsulating resin, and an area having small irregularities is formed on a lower side surface of the semiconductor chip, thereby improving adhesive strength between the semiconductor chip and the encapsulating resin and preventing penetration of moisture from outside.

Claim (Index 1):
A semiconductor device, comprising:\n a semiconductor chip having a bottom surface; a die pad supporting the semiconductor chip; an adhesive adhering the semiconductor chip and the die pad; a plurality of signal leads extending toward a side of the die pad; and an encapsulating body encapsulating the semiconductor chip and a part of each signal lead with a mold resin, wherein a side surface of the semiconductor chip comprises a first irregular side surface and a second irregular side surface located above the first irregular side surface, wherein the first irregular side surface and the second irregular side surface are both generally perpendicular to the bottom surface of the semiconductor chip and lie generally in the same plane, wherein the second irregular side surface comprises second irregularities that are larger than first irregularities on the first irregular side surface, and wherein the mold resin is in direct contact with the semiconductor chip and directly contacts the first irregular side surface and the second irregular side surface.
