Abstract:
1. A test circuit comprising: a substrate; a wiring section having a plurality of pieces of wiring and formed on said substrate; and a device-under-test section formed on said substrate, and having a device-under-test main body and a plurality of connecting electrodes for establishing connections between said device-under-test main body and said plurality of pieces of wiring, respectively, wherein an extending direction of a straight line connecting a position of a center of rotation in a plane of pattern formation of said device-under-test main body and each of said plurality of connecting electrodes is inclined at a predetermined angle to an extending direction of said plurality of pieces of wiring, and said plurality of connecting electrodes are arranged at positions such that connection relations between said plurality of connecting electrodes and said plurality of pieces of wiring are maintained even when said device-under-test main body and said plurality of connecting electrodes are rotated about said position of said center of rotation by 90 degrees relative to said wiring section in said plane of said pattern formation.
