Abstract:
A method of forming a capacitor mask includes the following steps. A bulk mandrel and a plurality of strip mandrels are formed on a mask layer. Spacers are formed on sidewalls of the bulk mandrel and the strip mandrels. The strip mandrels are removed while the bulk mandrel is reserved. A material fills in space between the spacers and on the bulk mandrel, wherein the material has a flat top surface. A patterned photoresist is formed to cover the bulk mandrel and a part of the spacers but exposing the other part of the spacers after filling the material.

Claim (Index 11):
The patterning method according to  claim 1 , wherein the mask layer comprises a polysilicon layer, a silicon nitride layer, an organic dielectric layer (ODL), a dielectric anti-reflection coating (DARC) layer stacked from bottom to top.
