Patent ID: 7405128

Claim:
A method for forming a dotted channel field effect device, comprising: providing a semiconductor substrate of a first conductivity type and having a surface; forming a well region of a second, opposite, conductivity type in a first part of the substrate extending to the surface; forming a body region of the first conductivity type in a second part of the substrate extending to the surface and in contact with or spaced apart from the well region; forming a control gate insulated from the surface over at least a portion of the body region and having therein multiple holes extending through the control gate and located over the portion of the body region; forming multiple highly doped regions of the first conductivity type in the body region through the multiple holes; forming source and drain regions of the second, opposite, conductivity type in the substrate on either side of the control gate; and providing electrical terminals to the source, drain, control gate and the multiple highly doped regions.
