Abstract
Disclosed is a bulk semiconductor device which employs a semiconductor element exhibiting negative conductivity under a high electric field. Said semiconductor element has at least two regions and at least one bridge portion and each region thereof is connected with the region adjacent thereto by a bridge portion. Means for controlling the lateral spatial growth of a high electric field domain is provided on or near each bridge portion. The growth of a high electric field domain generated in one of the regions into the adjacent region is controlled by applying a signal to said controlling means.
