Abstract:
A coupling device of a semiconductor device test apparatus employed to test at least one semiconductor device provided with a plurality of electrodes, the coupling device comprising:a circuit board provided with a plurality of electrodes that are in one-to-one correspondence to individual electrodes of the one semiconductor device under test; a connection plate having a first side facing said circuit board and a second side opposite said first side, and having a plurality of conductive portions to electrically connect on a one-to-one basis the electrodes of the one semiconductor device under test at the second side and the electrodes of said circuit board at the first side; and an elastic sheet sandwiched between the one semiconductor device under test and the connection plate, so as to be connected with both the one semiconductor device under test and the connection plate and carrying a pressure applied from the one semiconductor device under test onto the circuit board through the connection plate, said elastic sheet having linearly extending conductive elastic bodies, respective ones of the conductive elastic bodies being collinear with and electrically connecting respective opposing ones of the conductive portions of the connective plate and electrodes of the semiconductor device under test so that the conductive portions of the connection plate are electrically connected with the electrodes of the semiconductor device under test on a one-to-one basis.
