Patent ID: 11187741

Abstract:
An electrical characteristic measuring device (70) comprises an evaluation table (30) on which a semiconductor device (10) is to be placed, and a device pressing member (20) to press the device (10). The pressing member (20) comprises a non-conductive electrode pressing part (22) to press a device electrode part (12) and a flange pressing part (23) to press a flange portion (14) of a base material (11). In a flange contact part (42) of the flange pressing part (23), a surface facing the flange portion (14) of the base material (11) has the same shape as a flange facing surface of a screw head of a screw (16) for fastening to an apparatus on which the device 10 is to be mounted. When the device (10) is pressed against the evaluation table (30) by the pressing member (20), the flange pressing part (23) is placed at a position of the base material (11) corresponding to a position of a fastening portion (17) in which a screw insertion groove (15) is included and in which the screw (16) is fastened to the base material (11).
