WebTo increase the effective work function of a W /TiSiN metal gate stack without an equivalent oxide thickness (EOT) increase, we developed a process for high-pressure postmetallization annealing in diluted oxygen ambient. Compared with annealing in an atmospheric pressure, oxygen postmetallization annealing (PMA) in a high-pressure ambient (1-20atm) showed … WebThin TiSiN flat films deposited by MOCVD have been analysed in order to evaluate their microstructure and physical properties. TEM, XRR and RBS techniques have 掌桥科研 一站式科研服务平台

WebSep 1, 2004 · TiSiN Barrier metal TiCl4 SiH4 NH3 CVD Partial pressure Anti-oxidation 1. Introduction To achieve the integration required for dynamic random access memory (DRAM) devices larger than 256 Mbits requires advanced dielectric materials and complicated capacitor structures. Webas that of poly-Si of 1000 mVcm, (2) barrier metal is hardly oxidized for keeping its low resistivity, and (3) barrier metal should prevent oxygen diffusion into underlying poly-Si to … WebSep 25, 2024 · Selective TiSiN barrier was formed along via trench wall using direct contact via (DCV) process and subsequent Ta incorporation into Cu was found to significantly improve electromigration (EM) reliability. Also, a large reduction of 0.1mm via/line resistances is achieved. The proposed integration method allows MOCVD TiSiN usable as a clicker battle
