This work reports for the first time on the experimental study of the intrinsic voltage gain of InGaAs nTFET. The influence of Indium/Gallium composition and Zn diffusion temperature is analyzed. For a higher Indium amount (In0.7Ga0.3As compared to In0.53Ga0.47As) the band to band tunneling (BTBT) is improved due to bandgap narrowing. A higher Zn diffusion temperature gives rise to a higher source...
One transistor Floating Body RAM (1T FBRAM) has been thoroughly investigated as a potential candidate to replace the conventional DRAM, which is approaching the scaling limits at 20nm node [1–6]. 1T FBRAM offers better scalability, reduced process complexity and better compatibility with CMOS logic technology. However, FBRAM can hardly satisfy 64ms tail bit retention requirement [7] due to limited...
In this paper, a study of the leakage current through strained p+ n Si1-xGex/Si hetero-junctions is presented. The reduction in the band gap, induced by stress forces, and the doping level at the hetero-interface, due to the use of halo implantations, are varied by changing the Ge content and the recess depth. A comparison between simulation results and experimental data is presented to analyze the...
The introduction of high mobility channel materials together with new device structures with improved subthreshold slope provides a pathway into continuing the performance scaling of CMOS technology beyond the classical Si roadmap. The combination of Ge pMOS devices with nMOS devices made on very high electron mobility III/V compounds such as InGaAs can be achieved by selective growth on a Si-wafer,...
