Abstract:

Flash memory and methods of fabricating the same are disclosed. An illustrated example flash memory includes a first source formed within a semiconductor substrate; an epitaxial layer formed on an upper surface of the semiconductor substrate; an opening formed within the epitaxial layer to expose the first source; a floating gate device formed inside the opening; and a select gate device formed on the epitaxial layer at a distance from the floating gate device.
