Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP3793752
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a semiconductor device that can inhibit displacement in the thickness direction of a die pad 2 due to thermal expansion of a die pad support 3.
SOLUTION: The semiconductor device has a die pad 2, a die pad support 3 for supporting the die pad 2, a plurality of inner leads 4 whose tips are arranged in the vicinity of the die pad 2, and a semiconductor element 11 that is mounted to the die pad 2 and has external dimensions which are larger than those of the die pad 2. In this case, as the shape of the die pad support 3, a stress-relieving section 7 is provided in a region that is positioned between the die pad 2 and the tip of the inner lead 4, and the semiconductor element 11 is arranged on the stress-relieving section 7.
