Title: Semiconductor device
Inventor: TAKAGI YOSHIO
IPC: H01L23/28
Filed: 1992-08-05
Abstract: PURPOSE:To prevent the destruction of a semiconductor by a surge voltage by providing recessed sections extended in the flowing directions of electric currents flowing through electrode terminals on the outer peripheral surfaces of the electrode terminals. CONSTITUTION:When the switching frequency used by a module 12 is made higher, electric currents flow mostly in the outer peripheral surfaces of electrode terminals 8-1 and 8-2 due to skin effect. Because of a plurality of slits 13 formed along the flowing directions of the electric currents, the peripheral lengths and, accordingly, the outer peripheral areas of the terminals 8-1 and 8-2 increase in the flowing directions of the electric currents. The self-inductance L of the terminals 8-1 and 8-2 can be found from the expression. The l, mu0, ln, and w of the expression respectively represent the lengths of the terminals, vacuum permeability, natural logarithm, and width of the terminals. The (w) of the expression I is not the widths of the terminals, but becomes the peripheral lengths of the terminals when the switching frequency becomes higher. Since the (l) does not change, the self-inductance L of the terminals 8-1 and 8-2 is reduced and the switching frequency of the terminals 8-1 and 8-2 becomes higher. Therefore, even when the di/dt becomes larger at the time of turning off the module 12 from a turned on state, a surge voltage (=L.di/dt) becomes lower and the destruction of the module 12 can be prevented.
