Patent ID: 7935608

Claim:
A method for manufacturing an integrated circuit comprising at least one storage cell, the method comprising: providing a substrate having a first side and an opposing second side, the substrate comprising a plurality of trenches parallel to each other so that at least one dividing wall is formed between two adjacent trenches; filling the trenches with an insulating compound; providing a first insulating layer having a first side and an opposing second side on a top surface of at least one dividing wall wherein the first side of the first insulating layer is arranged on the first side of the substrate; providing a first conductive layer having a first side, an opposing second side, and side faces arranged from the first side and second side of the first conductive layer, wherein the first side of the first conductive layer is arranged on the second side of the insulating layer, wherein the first conductive layer protrudes at least partially above the insulating compound; providing a second conductive layer having a first side and an opposing second side, wherein the first side of the second conductive layer contacts at least a part of the second side and the side faces of the first conductive layer; and removing parts of the second conductive layer by means of an anisotropic etching.
