Abstract
To improve the reliability in an electric inspection of a semiconductor device. When a movable pedestalis being positioned relative to an arrangement direction of a plurality of second contact pinsby a positioning pinwhich a socketincludes, a substrate conduction test is performed by bringing a first contact pininto contact with a pre-stack landof a wiring substrateand of the a lower packageand moreover bringing the second contact pininto contact with a solder ball, and thus the electric inspection can be performed by precisely positioning the first contact pinside and the second contact pinside. Then, the reliability of the electric inspection can be improved.
