Abstract:
1. A semiconductor test apparatus comprising: a test apparatus main body for generating a test pattern provided to a semiconductor device; a test head which contacts said semiconductor device and provides said test pattern generated by said test apparatus main body to said semiconductor device; a cable for transferring said test pattern to said test head from said test apparatus main body wherein the cable is a flat cable in which a plurality of transmission lines are arranged flat; and a movable supporting unit for holding said cable, said movable supporting unit, when tension occurs in said cable, moving in a direction to release said tension; the test head is held rotatably by a fixed base, a width direction of the flat cable is substantially parallel to an axial direction of the cylindrical member, and wherein the rotation axis of the test head is substantially horizontal and is substantially parallel to the axial direction of the cylindrical member.
