No, this distance corresponds to the diameter of only a few atoms. Also, the wavelength of the
radiation needed to expose such patterns during fabrication is represents a serious problem.

From Fig. 1.4, there are approximately 600 million transistors on a complex Pentium IV
microprocessor in 2004. From Prob. 1.4, the number of transistors/P will be 8.85 x 1010 . in
2020. Thus there will be the equivalent of 8.85x1010 /6x108 = 148 Pentium IV processors.
