Abstract:
A method of forming multiple conductive structures in a semiconductor device includes forming spacers adjacent side surfaces of a mask, where the mask and the spacers are formed on a conductive layer. The method also includes etching at least one trench in a portion of the conductive layer not covered by the spacers or the mask. The method may further include depositing a material over the semiconductor device, removing the mask and etching the conductive layer to remove portions of the conductive layer not covered by the spacers or the material, where remaining portions of the conductive layer form the conductive structures.
