    摘要: In a lateral type p-n-p transistor, n-type semiconductor base substance and n-type base region is connected through a high resistance. Due to the high resistance, since an affect in a conjunction capacity between p-type collector (23) and n-type semiconductor base (11) substance can be lessen, a cutoff frequency in the lateral type p-n-p transistor can be heighten. Thereby, a high frequency in a high breakdown voltage lateral type semiconductor device can be improved. The contact condition is avoided by separating the interval between a high concentration of n-base region (11) having a high impurity concentration and a high concentration of p-collector region (23) having a low impurity concentration. Without the lowing in a breakdown voltage, the concentration of the p-collector region (23) having the low impurity concentration can be heighten, thereby a collector resistance can be made small. At the transistor operation time, the voltage between the emitter (21) and the base (11) can be lowered, a current capacity can be improved.
