Abstract

A non-volatile memory structure includes a semiconductor substrate and a first layer of a first dopant type in the semiconductor substrate. The non-volatile memory structure further includes a first well region of a second dopant type over the first layer, a second well region of the second dopant type over the first layer and spaced apart from the first well region, and a third well region of the first dopant type disposed between the first well region and the second well region and extending downward to the first layer.
