Patent number: 12087642Abstract: Techniques described herein enable respective (different) types of metal silicide layers to be formed for p-type source/drain regions and n-type source/drain regions in a selective manner. For example, a p-type metal silicide layer may be selectively formed over a p-type source/drain region (e.g., such that the p-type metal silicide layer is not formed over the n-type source/drain region) and an n-type metal silicide layer may be formed over the n-type source/drain region (which may be selective or non-selective). This provides a low Schottky barrier height between the p-type metal silicide layer and the p-type source/drain region, as well as a low Schottky barrier height between the n-type metal silicide layer and the n-type source/drain region. This reduces the contact resistance for both p-type source/drain regions and n-type source/drain regions.Type: GrantFiled: April 28, 2023Date of Patent: September 10, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Wei-Yip Loh, Yan-Ming Tsai, Yi-Ning Tai, Raghunath Putikam, Hung-Yi Huang, Hung-Hsu Chen, Chih-Wei Chang
