High-Performance and Low-Power CMOS Device Technologies Featuring Metal/High-k Gate Stacks with Uniaxial Strained Silicon Channels on (100) and (110) Substrates
CMOS technologies using metal/high-k damascene gate stacks with uniaxial strained silicon channels were developed. Gate electrodes of HfSix and TiN were applied to nFETs and pFETs, respectively.Expand

Extremely Low-voltage and High-speed Operation Bulk Thyristor-SRAM/DRAM (BT-RAM) Cell with Triple Selective Epitaxy Layers (TEL)
We have successfully developed an alternative SRAM cell for the first time using a bulk thyristor-RAM (BT-RAM) with triple selective epitaxy layers (TEL) for anode, n-base, and cathode. The n-base ofExpand

Both sand particles and organic substances enhance activity of free-living, nitrogen-fixing bacteria inhabiting soil of permafrost terrain in East Siberia
Although boreal forests produce large biomass, available nitrogen in the soil is poor, because of low soil temperature. Thus the mineralizing activities of the soil microorganisms are also very low.Expand
