Starting with the 45 nm node, a tradeoff between performance and density exists that become more severe at the 32 nm node. An in-depth analysis of the impact of pitch and increased parasitics on device performance in the 32 nm node is presented. To counteract these effects, reduction of parasitics, gate length scaling, and aggressive stress engineering are necessary. Optimized layout using a "relaxed-pitch"...
We present the state-of-the-art 45nm high performance bulk logic platform technology which utilizes, for the first time in the industry, ultra high NA (1.07) immersion lithography to realize highly down-scaled chip size. Fully renovated MOSFET integration scheme which features reversed extension and SD diffusion formation is established to meet Vt roll-off requirement with excellent transistor performance...
We report band-edge pFET threshold voltage (Vt ~ 0.28 V) for MoOxNy on HfSiON gate dielectric using a standard high temperature gate first metal-inserted poly-stack (MIPS) process flow. We also report p-FETs Vt of 0.45 V using a MoO x/SiON gate stack, meeting the requirement for 45nm high-V t CMOS technology. 30 % improvement in performance compared to our base-line poly-Si/SiON was observed by using...
