Abstract

A semiconductor device test socket has a shielding structure formed around each contactor so as to prevent signal delay or distortion during a test process and thereby enhance the test reliability. The socket includes a vertical probe comprising a contactor which has a contact terminal to be electrically connected to an external connection terminal of a semiconductor device. The shielding structure which is formed by laminating a conductive material on the outer edge of the contactor and is electrically connected to a ground. The socket further includes an elastic layer which is filled in the space between the contactor and the shielding structure, and surrounds the contactor such that the contact terminal of the contactor is exposed; and a connection film which is formed by laminating a conductive material so as to electrically connect shielding structures of multiple vertical probes.
