PRODUCTION METHOD FOR SEMICONDUCTOR DEVICE

摘要

Improvement in yield of a semiconductor device is obtained. In addition, increase in service life of a socket terminal is obtained. A projecting portion PJ1 and a projecting portion PJ2 are provided in an end portion PU of a socket terminal STE1. Thus, it is possible to enable contact between a lead and the socket terminal STE in which a large current is caused to flow, at two points by a contact using the projecting portion PJ1 and by a contact using the projecting portion PJ2, for example. As a result, the current flowing from the socket terminal STE1 to the lead flows by being dispersed into a path flowing in the projecting portion PJ1 and a path flowing in the projecting portion PJ2. Accordingly, it is possible to suppress increase of temperature of a contact portion between the socket terminal STE1 and the lead even in a case where the large current is caused to flow between the socket terminal STE1 and the lead.
