<p><P>PROBLEM TO BE SOLVED: To suppress peeling of an electrode member due to a torque applied on a fixed portion during tightening and removal of a bolt. <P>SOLUTION: An electrode member 8 has a columnar shape with different diameters, in which an upper portion 81 has a greater diameter and a lower portion 82 has a smaller diameter. A metallic support member 7 is provided between the electrode member 8 and a semiconductor chip 6. The support member 7 includes a mount 71, in which a leg portion 72 having a height dimension equal to or greater than a height of the lower portion 82 with the smaller diameter of the electrode member 8, a foot portion 74 provided in continuous with the leg portion 72, and a through hole 73 into which the lower portion of the electrode member fits are formed. The support member 7 is fixed to the semiconductor chip 6 by the foot portion 74. The lower portion 82 with the smaller diameter of the electrode member 8 is fit into the through hole 73 of the mount 71 of the support member 7, and the electrode member 8 is supportedly fixed on the mount 71 of the support member 7 by a bottom surface of the upper portion 81 with the greater diameter. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
