Abstract:
A method for manufacturing a semiconductor device having a multi-height structure is provided. The semiconductor device having a multi-height structure includes a silicon substrate. A first structure and a second structure are respectively formed on the silicon substrate and connected to each other. A limiting block is formed on the second structure and near an edge of the second structure beside the first structure. A bottom anti-reflection coating (BARC) layer is formed to blanketly cover the first structure, the second structure and the limiting block, in which the BARC layer includes a low-viscosity material, and the BARC layer overlying the top surface of the second structure has an external surface substantially parallel to the top surface of the second structure. Control gates are formed on the external surface of the BARC layer.

Claim (Index 11):
A method, comprising:\n forming a first gate layer and a dielectric layer over a first functional area of a semiconductor substrate, wherein the semiconductor substrate has the first functional area and a second functional area; forming a second gate layer over the dielectric layer; forming a third gate layer over the second gate layer and the second functional area of the semiconductor substrate; patterning the third gate layer to form a logic gate layer over the second functional area of the semiconductor substrate and a limiting block over the second gate layer, wherein the limiting block is directly over the first gate layer; and forming a bottom anti-reflection coating (BARC) layer over the logic gate layer, the second gate layer, and the limiting block, wherein a portion of the BARC layer is restrained over the first functional area by the limiting block.
