20220328312 · 2022-10-13 ·

A method for manufacturing semiconductor elements by a metal lift-off process and a semiconductor element manufactured thereby, include steps of photoresist-coating, exposing, developing, metal-coating, and lift-off. A photoresist layer can be removed with a photoresist stripper. Meanwhile, the metal on the top of the photoresist layer can also be removed when the photoresist layer is removed. The circuit layout required for the semiconductor element can thus be completed without an etching process. In addition, by setting the process parameters, the contour of the photoresist layer can present a certain angle, so that the metal on the surface of the photoresist layer can be completely removed, which saves costs and improves competitiveness.
