Abstract:
Methods disclosed herein form semiconductor devices having minimum spacings that correlate with spacer widths. An exemplary method includes forming a target layer over a substrate, forming a patterning layer over the target layer, and etching the target layer using the patterning layer as an etch mask. The patterning layer includes a first pattern feature, a second pattern feature spaced a first distance (corresponding with a first width of a first spacer fabricated during a first spacer patterning process) from the first pattern feature, and a third pattern feature spaced a second distance (corresponding with a second width of a second spacer fabricated during a second spacer patterning process) from the first pattern feature and a third distance (corresponding with a third width of a third spacer formed during the second spacer patterning process) from the second pattern feature.

Claim (Index 6):
The method of  claim 4 , wherein the forming the patterning layer over the target layer further includes:\n performing the second spacer patterning process to form a second spacer layer having the second width disposed along the sidewall of the first pattern feature and the third width disposed along a sidewall of the second pattern feature, wherein a space is defined between a first portion of the second spacer layer disposed along the sidewall of the first pattern feature and a second portion of the second spacer layer disposed along the sidewall of the second pattern feature; forming the third pattern feature over the target layer, wherein the third pattern feature fills a portion of the space defined between the first portion of the second spacer layer disposed along the sidewall of the first pattern feature and the second portion of the second spacer layer disposed along the sidewall of the second pattern feature; and removing the second spacer layer, such that the third pattern feature is separated from the first pattern feature by the second distance and the second target feature by the third distance.
