mean. n. 1. Something having a position, quality, or condition midway between extremes; a medium. 2. A number that typifies a set of numbers, such as a geometric mean or an arithmetic mean.he antilog of the mean of the logarithm of the calculated values, the same as the n th root of the product of the values. It is often a more useful mean for growth curves.
Threshold Voltage Threshold voltage, V, is defined as the minimum gate bias which can form a conducting channel between the source and drain. For power MOSFETs, it is usually measured at the drain-source current of 250uA. Gate oxide thickness and doping concentration of the channel can be used to control the V .
â¢ It has taken ~10 years to bring â3 â Dâ transistors into volume production. â¢ Multi â gate MOSFETs provide a pathway to achieving lower power and/or improved performance. â¢ Further evolution of the MOSFET to a stacked â channel structure may occur by the end of the roadmap.ooking to the Futureâ¦ 2010 International Technology Roadmap for Semiconductors (ITRS) 2012 2014 2016 2018 2020 2022 2024Gate Length 24 nm 18 nm 15 nm 13 nm 11 nm 10 nm 7 nmGate Oxide Thickness, T OX (nm)Drive Current, I DSAT End of Roadmap(always ~15 yrs away!) 46.
