    摘要: A semiconductor device having high withstand strength against destruction. The semiconductor device 1 includes guard buried regions 44b of second conductivity type concentrically provided on a resistance layer 15 of first conductivity type and base diffusion regions 17a are provided inside of the guard buried region 44b and base buried regions 44a of the second conductivity type are provided on the bottom surface of the base diffusion regions 17a. A distance between adjacent base buried regions 44a at the bottom of the same base diffusion region 17a is Wm1, a distance between adjacent base buried regions 44a at the bottom of the different base diffusion regions 17a is Wm2, and a distance between the guard buried regions 44b is WPE. A ratio of an impurity quantity Q1 of the first conductivity type and an impurity quantity Q2 of the second conductivity type included inside the widthwise center of the innermost guard buried region 44b is 0.90
