1. A semiconductor device having first and second opposed major surfaces, the semiconductor device comprising a semiconductor first region provided between second and third regions such that the second region forms a rectifying junction with the first region and separates the first region from the first major surface and the third region separates the first region from the second major surface, the first region having dispersed therein a plurality of resistive paths each extending through the first region from the second to the third region such that, in use, when a reverse biasing voltage is applied across the rectifying junction an electrical potential distribution is generated along the resistive paths which causes a depletion region in the first region to extend through the first region to the third region to increase the reverse breakdown voltage of the device.
