Patent ID: 8759179

Claim:
A method of forming a gate pattern, the gate pattern comprising a plurality of gate bars parallel to each other in a first direction, each gate bar being broken up by gaps, wherein the method comprises the following steps sequentially: forming a gate material layer on a substrate; making an etching characteristic of the gate material layer at least at positions where the gaps are to be formed different from an etching characteristic of the gate material layer at remaining positions; forming a second resist layer on the gate material layer on the substrate; performing a second patterning process on the second resist layer so as to form a plurality of openings parallel to each other and extending continuously in the first direction; performing a first etching process on the gate material layer with the second resist layer after the second patterning process as a mask, wherein portions of the gate material layer at least at the positions where the gaps are to be formed are selectively left; and performing a second etching process on the gate material layer so as to selectively remove the portions of the gate material layer at least at the positions where the gaps are to be formed.
