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 1):
A method comprising:\n forming a target layer over a substrate; forming a patterning layer over the target layer, wherein the patterning layer includes:\n a first pattern feature, \n a second pattern feature spaced a first distance from the first pattern feature, wherein the first distance corresponds with a first width of a first spacer fabricated during a first spacer patterning process, and \n a third pattern feature spaced a second distance from the first pattern feature and a third distance from the second pattern feature, wherein the second distance corresponds with a second width of a second spacer fabricated during a second spacer patterning process and the third distance corresponds with a third width of a third spacer formed during the second spacer patterning process; and \n etching the target layer using the patterning layer as an etch mask, such that the target layer includes a first target feature that corresponds with the first pattern feature, a second target feature that corresponds with the second pattern feature, and a third target feature that corresponds with the third pattern feature.
