Abstract
A connecting unit to test a semiconductor chip and an apparatus to test the semiconductor chip having the same include a plurality of connectors, on which a semiconductor chip having a certain pattern of electrical connection terminals, having a plurality of holes, cables configured to electrically connect the electrical connection terminals to the exterior, and coupling units configured to selectively electrically connect the cables to the electrical connection terminals through the holes. Therefore, it is possible to perform electrical tests of semiconductor chips having various patterns of electrical connection terminals and receive the semiconductor chips in a tray at a time.
