Abstract
An electrical circuit, planar diode, and method of forming a diode and one or more CMOS devices on the same chip. The method includes electrically isolating a portion of a substrate in a diode region from other substrate regions. The method also includes recessing the substrate in the diode region. The method further includes epitaxially forming in the diode region a first doped layer above the substrate and epitaxially forming in the diode region a second doped layer above the first doped layer.
