Single-poly EPROM and method for forming the same










Image Number 5 for United States Patent #6917070.

A single-poly EPROM and method for forming the same. The single-poly EPROM has an isolation region disposed in a substrate to define a striped active area. A deep n-well is located under the isolation region and the striped active area. A gate oxide layer is disposed on the substrate at the striped active area. A pair of striped selective gates perpendicular to the striped active area are disposed on the gate oxide layer and the isolation region. A pair of islanded floating gates are disposed on the gate oxide layer at the active area, with a gap between the pair of floating gates and the pair of selective gates. A striped p-well is disposed in the deep n-well between the pair of selective gates and below the pair of selective gates and portions of the pair of floating gates. A pair of sources are disposed on both sides of the p-well, and connected to each other through the deep n-well. A drain is disposed in the p-well between the pair of selective gates.
