A semi-conductor body contains a planar PN junction extending to the surface of the body which is bevelled in the vicinity of the junction so that the cross-sectional area, parallel to the junction, of the body is less on the lower resistivity side of the junction than on the higher resistivity side, the angle of the bevel lying between given limits related to the impurity concentrations on the two sides of the junction and to the depth of the junction in the body. Breakdown of the junction due to excessive reverse bias occurs in the bulk of the body rather than at the surface. |
