Abstract

Official abstract text for this publication.

In a contact terminal, a first touch portion and a second touch portion of a movable piece and a first touch portion and a second touch portion of a movable piece bite into and thus pinch a spherical surface of a bump of a semiconductor device. In this state, when an electrode surface of the semiconductor device is warped upward during a test and the bump is about to be moved up, an inclined surface of a fixing portion of the movable piece and an inclined surface of a fixing portion of the movable piece fix the spherical surface of the bump.

First claim

Opening claim text (preview).

What is claimed is: 1. A contact terminal comprising: at least one movable piece selectively coming into contact with a spherical electrode portion in a semiconductor device; and a terminal portion coupled to a proximal end portion of the movable piece, wherein a contact point portion of the movable piece includes at least one touch portion extending along a longitudinal direction of the movable piece, and coming into contact with the spherical electrode portion, and a fixing portion intersecting a tip end of the touch portion and being connected to the tip end of the touch portion, and having an inclined surface portion to fix the spherical electrode portion, a ridge line of the touch portion projecting farther outwardly than a ridge line of the fixing portion. 2. The contact terminal according to claim 1 , comprising a pair of the movable pieces, wherein a contact point portion of one of the pair of the movable pieces includes at least one touch portion extending along a longitudinal direction of the one movable piece, and coming into contact with the spherical electrode portion, and a fixing portion intersecting a tip end of the touch portion, and having an inclined surface portion to fix the spherical electrode portion, and a contact point portion of the other one of the pair of the movable pieces includes at least one touch portion extending along a longitudinal direction of the other movable piece, and coming into contact with the spherical electrode portion, and a fixing portion intersecting a tip end of the touch portion, and having an inclined surface portion to fix the spherical electrode portion. 3. The contact terminal according to claim 1 , comprising a pair of the movable pieces, wherein a contact point portion of one of the pair of the movable pieces includes a pair of touch portions extending in such a way as to be opposed to each other at a predetermined interval and along a longitudinal direction of the one movable piece, and coming into contact with the spherical electrode portion, and a fixing portion intersecting a tip end of each touch portion, and having an inclined surface portion to fix the spherical electrode portion, and a contact point portion of the other one of the pair of the movable pieces includes a pair of touch portions extending in such a way as to be opposed to each other at a predetermined interval and along a longitudinal direction of the other movable piece, and coming into contact with the spherical electrode portion, and a fixing portion intersecting a tip end of each touch portion, and having an inclined surface portion to fix the spherical electrode portion. 4. The contact terminal according to claim 1 , comprising a pair of the movable pieces, wherein a contact point portion of one of the pair of the movable pieces includes a pair of touch portions extending in such a way as to be opposed to each other at a predetermined interval and along a longitudinal direction of the one movable piece, and coming into contact with the spherical electrode portion, and a contact point portion of the other one of the pair of the movable pieces includes a pair of touch portions extending in such a way as to be opposed to each other at a predetermined interval and along a longitudinal direction of the other movable piece, and coming into contact with the spherical electrode portion, and a fixing portion intersecting a tip end of the each touch portion, and having an inclined surface portion to fix the spherical electrode portion. 5. The contact terminal according to claim 1 , comprising a pair of the movable pieces, wherein a contact point portion of one of the pair of the movable pieces includes at least one touch portion extending along a longitudinal direction of the one movable piece, and coming into contact with the spherical electrode portion, and a contact point portion of the other one of the pair of the movable pieces includes a pair of touch portions extending in such a way as to be opposed to each other at a predetermined interval and along a longitudinal direction of the other movable piece, and coming into contact with the spherical electrode portion, and a fixing portion intersecting a tip end of each touch portion, and having an inclined surface portion to fix the spherical electrode portion. 6. The contact terminal according to claim 1 , comprising a pair of the movable pieces, wherein a contact point portion of one of the pair of the movable pieces includes at least one touch portion extending along a longitudinal direction of the one movable piece, and coming into contact with the spherical electrode portion, and two fixing portions intersecting a tip end of each touch portion, each fixing portion having an inclined surface portion to fix the spherical electrode portion, and a contact point portion of the other one of the pair of the movable pieces includes at least one touch portion extending along a longitudinal direction of the other movable piece, and coming into contact with the spherical electrode portion, and two fixing portions intersecting a tip end of each touch portion, each fixing portion having an inclined surface portion to fix the spherical electrode portion. 7. An IC socket comprising: a socket body including the contact terminal according to claim 1 ; a semiconductor device placement portion on which a semiconductor device having a spherical electrode portion is detachably placed, the semiconductor device placement portion being provided in the socket body; and a movable piece drive mechanism portion movably provided in the socket body, and configured to actuate at least one of a pair of movable pieces of the contact terminal in such a way as to approach or move away from the spherical electrode portion.
