Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2011082345
Kind Code:
A
Abstract:

To effectively dissipate heat generated by a semiconductor chip when a semiconductor device is in operation, and to suppress variance in heat dissipation in a device and variance in dissipation between devices.

The semiconductor device includes: a wiring board 31 provided with an external connection terminal 9 on a lower surface; a semiconductor chip 1 mounted on an upper surface of the wiring board 31; a cap-shaped heat dissipation member 11 installed on the upper surface of the wiring board 31 to cover the semiconductor chip 1; a fixing pin 21 for fixing the heat dissipation member 11 on the upper surface of the wiring board 31; and a heat transfer material 2 sandwiched between a lower surface of a part of the heat dissipation member disposed right above the semiconductor chip 1 and an upper surface of the semiconductor chip 1.
