In this paper, we have done a comprehensive study of the junction anneal strategy (by spike and/or laser) for advanced technology nodes with Hk/MG and high-k capping film to control the eWF. It has been shown that a low long channel Vth is easily achievable with anneal sequence optimization. In particular with the help of laser which creates more dipoles for NMOS case with La-based capping. But also...
In this paper, we report on the integration of laser-annealed junctions into a state-of-the-art high-k/metal gate process flow. After implant optimization, we achieve excellent Lg scaling of 15/30 nm over a spike reference, for nMOS and pMOS respectively, without any performance loss. This enables to fabricate transistors with Lgmin meeting the 32 nm node requirement. In addition, we highlight the...
