摘要:
A method for manufacturing a metal structure using a trench includes etching a semiconductor substrate to form a trench, depositing a seed layer over the semiconductor substrate including in the trench, stacking an insulating layer over the seed layer, removing a portion of the insulating layer to expose a portion of the seed layer at a bottom of the trench, filling the trench with a metal material, and removing the seed layer and the insulating layer on the semiconductor substrate. As a result, a subsequent process in forming a multi-layered structure may be easily carried out, thereby simplifying a manufacturing process.
