In this talk the device/process architecture and modeling of buried-halo MOSFET (BH-MOSFET) devices for low power application are discussed. The continuous scaling of planar MOSFETs towards 5-nm regime has become more challenging due to fundamental device-physics constraints including short-channel effect (SCE) and process-variability. The SCE degrades the performance of scaled devices with higher sub-threshold swing and leakage current and poses a sever challenge to control device performance by gate bias. On the other hand, the process variability severely impacts the delay and power variability in VLSI devices, circuits, and chips. The impact of the increasing amount of within-die process variability on the yield of VLSI circuits, such as SRAM, has imposed an enormous challenge to design advanced VLSI chips using bulk-CMOS technology. In order to mitigate the risk of process variability, new statistical design methodologies have evolved. Though, these statistical modeling techniques allow designers best possible solution to optimize the impact of variability, however, process variability constraint limits the circuit performance and yield. However, to mitigate the risk of process variability, variability-tolerant device architecture is required. In this talk, the architecture and modeling of BH-MOSFET devices for continuous scaling of planar MOSFETs in the nano nodes will be discussed.
