Bright Peaks for Smaller Chips
Salden writes "University of Wisconsin scientists propose a way to create 20nm chip features. They were investigating the limits of X-ray lithography and discovered that they could control the phase of X-rays by adjusting the gap between a mask and wafer. Pretty cool."
you must be talking about high-Vt transistors. because operating speed is crucial, most state-of-the-art transistors have Vts around .3-.4 V.
the smaller transistors will definitely lead to other problems for analog circuits. First of all, short-channel noise increases with maximum voltage decreasing, making it harder to achieve low noise figures.
