Exercise 2.1-3

What does it take to build a 4 GHz Microprocessor?

	A typical MOS transistor of 200x (x = 0 .... 5) vintage has a "gate length" (= distance between source an drain of about 0.5 µm and is run at about 3 V
		1.) What is the mobility the material (= semiconductor) must have? Discuss the result for known mobility values and consider the following points Transistor speed = device speed ?? Mobility range for a given material ?? Could we have powerful PCs without micro- or nanotechnology ??
		2.) How could you increase the speed for a given material In principal? Considering that there limits. e.g. to field strengths?

	Solution
