Abstract
An isolated diode comprises a floor isolation region, a dielectric-filled trench and a sidewall region extending from a bottom of the trench at least to the floor isolation region. The floor isolation region, dielectric-filled trench and a sidewall region are comprised in one terminal (anode or cathode) of the diode and together form an isolated pocket in which the other terminal of the diode is formed. In one embodiment the terminals of the diode are separated by a second dielectric-filled trench and sidewall region.
