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 3):
A semiconductor device, comprising:\n a semiconductor chip having top and bottom surfaces bounded by a side surface; a die pad on which the bottom surface of the semiconductor chip is disposed; an adhesive interposed between the bottom surface of the semiconductor chip and the die pad; signal leads extending toward the die pad; and an encapsulating resin encapsulating the semiconductor chip and a part of each signal lead, wherein the side surface of the semiconductor chip comprises a roughened lower surface portion extending from the bottom surface toward the top surface of the semiconductor chip and on which first roughened surface irregularities are formed, and a roughened upper surface portion extending from the lower surface portion to the top surface of the semiconductor chip and on which second roughened surface irregularities are formed, wherein the roughened lower and upper surface portions of the side surface lie generally in the same plane, wherein the second roughened surface irregularities are larger than the first roughened surface irregularities, and wherein the encapsulating resin is in direct contact with the semiconductor chip and directly contacts the first and second roughened surface irregularities.
