Patent ID: 7927964

Claim:
A method of forming a semiconductor construction, comprising: forming a first material over semiconductor substrate; forming a patterned mask over the first material; transferring a pattern from the mask through the first material to form openings extending through the first material; forming electrically conductive material over the first material and within the openings; removing the electrically conductive material from over the first material while leaving the electrically conductive material within the openings as a plurality of spaced apart electrically conductive pedestals; the electrically conductive pedestals being separated from one another by the first material; removing the first material from between the electrically conductive pedestals; after removing the first material, forming one or more low k dielectric materials between the electrically conductive pedestals; and wherein the forming the patterned mask comprises: forming photoresist over the first material; photolithographically patterning the photoresist to form a first pattern of the photoresist, the first pattern comprising a plurality of features; forming spacers along the features; and removing the photoresist to leave the patterned mask consisting of the spacers.
