Thereafter, the other end of the wire 15 is formed with uneven parts at the edge 16 of the lead 13 and the bends 21, 21. Accordingly, even if the wire 15 once in contact therewith tends to slide laterally, since the frictional coefficients of the edge 16 or the bends 21, 21 with the wire 15 is large, its slide is prevented by the uneven part.

Title: Semiconductor device and semiconductor wafer
Inventor: MORI MUTSUHIRO
IPC: H01L29/74
Filed: 1988-07-04
Abstract: PURPOSE:To reduce an insulating gate capacitance and to decrease a switching loss when a device is turned OFF by a method wherein an n<-> layer is interposed between a p<+> substrate and an n-layer in contact with the p<+> substrate. CONSTITUTION:An n<-> layer 22 is formed on a p<+> substrate 10 through an epitaxial growth, and then an n-layer 20 is formed through a diffusion or an ion implantation or again through an epitaxial growth. And, a depletion layer is made to extend to the n<-> layer 22 through a diffusion potential of the p<+> substrate 10 and the n<-> layer 22, and a junction capacitance between the p<+> substrate and the n<-> layer 22 grows small. In result, the capacitance between a gate and a collector decreases, and even if a voltage rises sharply at the turn-off of a device, a current, which flows through the collector, the gate, and the emitter through the intermediary of the capacitance between the gate and the collector and between the gate and the emitter, decreases and a gate voltage can be prevented from rising. By these processes, a semiconductor device is prevented from turning ON again, so that a switching loss can be prevented from increasing at turn-OFF.
