Abstract
A semiconductor configuration for current control has an n-type first semiconductor region with a first surface, a p-type covered island region, within the first semiconductor region, with a second surface, an n-type contact region arranged on the second surface within the island region and a lateral channel region, formed between the first and second surface as part of the first semiconductor region. The channel is part of a current path from or to the contact region. The current within the lateral channel region may be influenced by at least one depletion zone. A lateral edge of the lateral channel region extends as far as the contact region.
