In this paper, the design guideline with emphasis on CMOS device reliability has been addressed. Advanced 65 nm CMOS devices with various strain engineering were evaluated. For nMOSFETs, charge pumping (CP) measurement is efficient for their reliability characterizations. Although biaxial strained SiGe-channel device provides good driving current enhancement, it suffers from the Ge out-diffusion such...
We present an optimal partially-depleted silicon-on-insulator (PD-SOI) platform, which demonstrates superior performance of SOI over bulk technology. Device optimization is performed in terms of circuit switch speed and power consumption through channel and S/D engineering. Fundamental device characteristics, SRAM yields, reliability assessment, and physical IP qualification for our PD-SOI platform...
In this paper, the device performance in terms of its transport characteristics and reliability of the MOS devices on the SOI and strained-SOI have been examined. For the first time, both the transport and reliability characteristics have been established from experimental SOI and SSOI nMOSFETs. It was characterized by two parameters, the ballistic efficiency and the injection velocity. Experimental...
Device optimization on partially-depleted silicon-on-insulator (PD-SOI) CMOS is systematically performed in terms of circuit switching speed and power consumption. The effects of several key factors, such as threshold voltage (Vth), pre-amorphization implantation (PAI), and silicon film thickness (Tsi), are fully investigated and optimized to achieve optimal ring-oscillator performance. We found that...
SOI is today mainly used for high-speed CPU applications. The advantages brought by SOI are still questioned or not clearly understood and little information has been published about the comparison between bulk and SOI CMOS. First reason is that this comparison to be representative must be done for same process features such as gate length and gate oxide thickness, second reason is that designing...
