  • Patent number: 4429324
    Abstract: The present invention provides an improved Zener diode structure which avoids adverse structure causing leakage current or short circuits, for example. The pn junction is formed on a region of a first conductivity material below a window on the surface of the material. A second conductivity material fills the window to form the pn junction, and forms a sub-region at least at the edges of the window and extending substantially below the pn junction to maintain the pn junction far from the edges of the window.
