Abstract
A method for forming an integrated circuit is provided. The method includes forming a dielectric layer over a cell region and a logic region of a substrate; forming a resistance switching layer over the dielectric layer; performing at least one etch process to pattern the resistance switching layer into a plurality of resistance switching elements in the cell region, in which a first portion of the dielectric layer in the logic region is less etched by the etch process than a second portion of the dielectric layer in the cell region.
