Device integration issues towards 10 nm MOSFETs

• An overview of critical integration issues for future generation MOSFETs towards 10 nm gate length is presented. Novel materials and innovative structures are discussed. Implementation of high K gate dielectrics is presented and device performance is demonstrated for TiN metal gate surface channel SiGe MOSFETs with a gate stack based on ALD-formed HfO(2)/Al(2)O(3). Low frequency noise properties for those devices are also analyzed. A selective SiGe epitaxy process for low resistivity source/drain contacts has been developed and implemented in pMOSFETs. A spacer pattering technology using optical lithography to fabricate sub 50 nm high-frequency MOSFETs and nanowires is demonstrated, Finally ultra thin body Sol devices with high mobility SiGe channels are demonstrated.
