Publication number: 20240105444Abstract: Methods for reducing contact resistance include performing a selective titanium silicide (TiSi) deposition process on a middle of the line (MOL) contact structure that includes a cavity in a substrate of dielectric material. The contact structure also includes a silicon-based connection portion at a bottom of the cavity. The selective TiSi deposition process is selective to silicon-based material over dielectric material. The methods also include performing a selective deposition process of a metal material on the MOL contact structure. The selective deposition process is selective to TiSi material over dielectric material and forms a silicide capping layer on the silicon-based connection portion. The methods further include performing a seed layer deposition process of the metal material on the contact structure.Type: ApplicationFiled: April 26, 2023Publication date: March 28, 2024Inventors: Jiang LU, Liqi WU, Wei DOU, Weifeng YE, Shih Chung CHEN, Rongjun WANG, Xianmin TANG, Yiyang WAN, Shumao ZHANG, Jianqiu GUO
