Semiconductor device and method of manufacturing same
To improve the heat dissipation characteristics of a semiconductor device.The semiconductor device has a die pad, a heat dissipating plate in the form of a frame arranged between the die pad and a plurality of leads so as to surround the die pad, a plurality of members that connect the die pad and the inner edge of the heat dissipating plate, and a suspension lead linked to the outer extension of the heat dissipating plate, wherein a semiconductor chip the outer shape of which is larger than the die pad is mounted over the die pad and the members. The top surface of the die pad and the top surface of the members at the part in opposition to the back surface of the semiconductor chip are bonded to the back surface of the semiconductor chip in their entire surfaces with a silver paste. Heat in the semiconductor chip is conducted from the back surface of the semiconductor chip to the heat dissipating plate via the silver paste, the die pad, and the member, and dissipated to the outside of the semiconductor device therefrom via the lead.
