Publication number: 20240096998Abstract: The present disclosure describes a method for forming metallization layers that include a ruthenium metal liner and a cobalt metal fill. The method includes depositing a first dielectric on a substrate having a gate structure and source/drain (S/D) structures, forming an opening in the first dielectric to expose the S/D structures, and depositing a ruthenium metal on bottom and sidewall surfaces of the opening. The method further includes depositing a cobalt metal on the ruthenium metal to fill the opening, reflowing the cobalt metal, and planarizing the cobalt and ruthenium metals to form S/D conductive structures with a top surface coplanar with a top surface of the first dielectric.Type: ApplicationFiled: November 21, 2023Publication date: March 21, 2024Applicant: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Shuen-Shin LIANG, Chij-chien CHI, Yi-Ying LIU, Chia-Hung CHU, Hsu-Kai CHANG, Cheng-Wei CHANG, Chein-Shun LIAO, Keng-chu LIN, KAi-Ting HUANG
