The rapid improvement in silicon technology has enables the electronic industry to progress steadily over the past 50 years.It
is this technological stride that make computers to shrink in cost and
size .But a question still persists whether the present rate of
progress will continue for the next 50 years. The essential ingredient
to the progress had been the process of miniaturization.The
road to advances beyond a decade into the future has always been
obscure and has stimulated many speculations as to where
miniaturization must end. The problems and their solutions rising from
the continued miniaturization are examined in the perspective of the
fundamental limits imposed by nature.An
understanding of the fundamental limits is important, since we can
shape the chips in such a way that in future we get better
computational speed and efficiency..
