Abstract
Disclosed is an improved lateral effect position-sensitive device having a clover design and including a semiconductor body including a first doped surface-oriented region of one conductivity type, a second doped surface-oriented region of opposite conductivity type, and a layer of intrinsic semiconductor material separating the first region and the second region. The first region has concave boundaries and at least four vertices. A first plurality of electrical contacts electrically contacts the vertices, and a second plurality of contacts electrically contacts intermediate portions of the concave boundaries. Conductors electrically interconnect each of the second plurality of contacts with one of the first plurality of contacts.
