Pattern Transfer Failed? Aligning Photolithography and Etching the Right Way
In precision manufacturing, pattern transfer is a critical step. The coordination between photolithography and etching directly determines pattern accuracy and process success. In many process failures, transfer issues are not caused by a single step alone, but by poor alignment between lithography, which defines the pattern, and etching, which transfers it into the substrate. Any mismatch in process timing or parameters may lead to pattern distortion, dimensional deviation or device failure.
