Patent ID: 7102218

Claim:
A semiconductor package with a chip supporting member, comprising: a lead frame having at least a die pad and a plurality of leads; a plurality of chip supporting members each having a first surface and a second surface opposed to the first surface and each having an identical height, wherein the second surfaces of the chip supporting members are attached to the die pad, making the first surfaces of the chip supporting members flush with each other; a chip having a first surface and a second surface opposed to the first surface, wherein the second surface of the chip is mounted on the first surfaces of the chip supporting members, and the first surface of the chip is electrically connected to the lead frame; and an encapsulant formed by a resin for encapsulating the chip supporting members, the chip and the lead frame; wherein the chip supporting members are interposed between the chip and the die pad, and the chip is spaced apart from the die pad by the chip supporting members, each of the chip supporting members having a height larger than about 3 mils for accommodating a size of fillers of the resin and made of a material having a coefficient of thermal expansion similar to that of the chip, wherein the material of each of the chip supporting members is selected from a group consisting of a dummy die of a same material as the chip, a copper plate, and a polymer material having the coefficient of thermal expansion similar to that of the chip.
