Abstract:
An integrated circuit includes a substrate, a first isolation feature, and a plurality of memory cells. The substrate has a cell region, a peripheral region, and a transition region between the cell region and the peripheral region. A top surface of the cell region is lower than a top surface of the peripheral region, and the substrate includes at least one protrusion portion in the transition region. The first isolation feature is in the transition region and covers the protrusion portion of the substrate. The memory cells are over the cell region of the substrate.

Claim (Index 15):
A method for manufacturing an integrated circuit, the method comprising:\n recessing a substrate until a top surface of a cell region of the substrate is lower than a top surface of a peripheral region of the substrate; forming a floating gate film over the cell region of the substrate; forming a pad layer over the floating gate film and the substrate, wherein the pad layer is in contact with the floating gate film and the peripheral region of the substrate; forming a mask layer over the pad layer; form at least one first trench in the mask layer, the pad layer, the floating gate film, and the cell region of the substrate; forming a first isolation feature in the first trench; and forming at least one memory cell over the cell region of the substrate, wherein a floating gate of the memory cell is formed from the floating gate film.
