Patent ID: 7230830

Claim:
A semiconductor device socket comprising: a socket body provided with a semiconductor device accommodation portion for accommodating a semiconductor device and a group of contact terminals for electrically connecting the semiconductor device accommodated in said semiconductor device accommodation portion with external electronic circuits; a holding device provided around said semiconductor device accommodation portion to be capable of selectively occupying either a position for holding the semiconductor device in said semiconductor device accommodation portion or a position for releasing the semiconductor device therefrom; a holding device driving section for driving said holding device; and a heat sink member detachably disposed in said socket body, having a contacting section brought into contact with a periphery of the semiconductor device disposed in said semiconductor device accommodation portion to cool the semiconductor device; wherein when said heat sink member is attached to said socket body, the contacting section of said heat sink member is brought into contact with the periphery of the semiconductor device while the holding device occupies the released position by said holding device driving section.
