A semiconductor test apparatus capable of securely having the contact pin and the external contact terminal held in contact with each other even in case where the vertical type handler is used. The semiconductor test apparatus comprises: a test socket having a socket surface formed thereon, the socket surface having a contact pin towering therefrom; and a semiconductor transport fixture having a concave portion formed thereon, the concave portion adapted to receive therein an IC under test, wherein the test socket has a position adjustment guide provided thereon, the semiconductor transport fixture has a guide through bore formed therein, the guide through bore adapted to receive the position adjustment guide therethrough when the IC under test comes under test, and either one of the position adjustment guide or the guide through bore is formed in a tapered shape.

Semiconductor test apparatus for testing semiconductor devices

A novel jig device useful for transporting and testing an IC chip is disclosed. The jig device comprises a main jig body, having a holding part onto which the IC chip to be tested is attracted and held and at least one suction path is formed, and at least one contact probe arranged in the suction path of the main jig body. The main jig body comprises preferably a base part and front head part. The contact probe connects electronically between a terminal of the IC chip held at the holding part and an electrode of circuit board of tester.
