<p>PURPOSE:To prevent a latch-up phenomenon and a latch-back phenomenon from being caused by specifying a ratio of an interval between adjacent base regions of a part close to a part to which a connecting conductor of a main electrode has been fixed and bonded to a width of a base region in a direction toward the interval. CONSTITUTION:A width Lw2 of a p-base region 3 under a bonding part of a conductor 11 such as an Al wire or the like bonded to an emitter electrode 9 is made nearly identical to a width Lw1 of a p-base region which is distant from a bonding part. An interval Lg2 between adjacent p-base regions directly under the bonding part is made smaller than an interval Lg1 between regions which are distant from the bonding part. In this case, Lg/Lw is set to a range of 0.2 to 0.4.</p> |
