Method of patterning target layer KU Leuven
The disclosed technology generally relates to patterning structures in semiconductor fabrication, and more particularly to patterning structures using mask structures having bridged lines. In one aspect, a method for patterning a target layer comprises: forming on the target layer a plurality of parallel material lines spaced apart such that longitudinal gaps exposing the target layer are formed between the material lines, filling the gaps with a sacrificial material, forming a hole by removing the sacrificial material along a portion of one of the gaps, the hole extending across the gap and ...
