Abstract:
Patterning techniques are disclosed that can relax overlay requirements and/or increase integrated circuit design flexibility. An exemplary method includes forming a first set of fins and a second set of fins having different etch sensitivities on a material layer. The fins of the second set of fins are interspersed between the fins of the first set of fins. A first patterning process removes a subset of the first set of fins and a portion of the material layer underlying the subset of the first set of fins. The first patterning process avoids substantial removal of an exposed portion of the second set of fins. A second patterning process removes a subset of the second set of fins and a portion of the material layer underlying the subset of the second set of fins. The second patterning process avoids substantial removal of an exposed portion of the first set of fins.

Claim (Index 9):
A method comprising:\n forming first fins, second fins, and third fins over a material layer, wherein the second fins are disposed along sidewalls of the first fins and the third fins are disposed along sidewalls of the second fins; forming a first patterning layer over the first fins, the second fins, and the third fins; patterning the first patterning layer to expose a portion of the first fins; performing a first etching process configured to etch the exposed portion of the first fins and the material layer underlying the exposed portion of the first fins and further configured to avoid substantial etching of the second fins and the third fins; forming a second patterning layer over the first fins, the second fins, and the third fins; patterning the second patterning layer to expose a portion of the third fins; performing a second etching process configured to etch the exposed portion of the third fins and the material layer underlying the exposed portion of the third fins and further configured to avoid substantial etching of the first fins and the second fins; depositing a fill material in at least one recess formed in the material layer by the first etching process and the second etching process; and removing remaining first fins, second fins, and third fins.
