Abstract
A method for forming a hybrid-bonding structure is provided. The method includes forming a first dielectric layer over a first semiconductor substrate. The first semiconductor substrate includes a conductive structure. The method also includes partially removing the first dielectric layer to form a first dielectric dummy pattern, a second dielectric dummy pattern and a third dielectric dummy pattern and an opening through the first dielectric layer. The first dielectric dummy pattern, the second dielectric dummy pattern and the third dielectric dummy pattern are surrounded by the opening. In addition, the method includes forming a first conductive line in the opening. The first conductive line is in contact with the conductive structure.
