Nanotechnology is receiving a lot
of attention from companies, universities
and governments. The US
National Nanotechnology Initiative
is matched by initiatives in Europe
and Asia. But what does it mean for
existing businesses and new businesses
in the electronics market. Is
it a real tool for today...or are the
applications way out in the future?
Will it be economic or outrageously
costly?
The presentation will outline areas
in Nanotechnology with specific
impact on semiconductors, passive
components, display materials,
packaging and interconnection.
Long term issues
Once CMOS technology dips below
about 20nm resolution, quantum
effects such as electron tunneling
start to result in phenomena like
unacceptable leakage. The only
way to move below that size is to
utilise these and other quantum
effects in new types of minute
structures, be they pure electronic
or bio-electronic (remember,
the most effective and energy efficient
computer available sits on
your shoulders!). We know that
if we extrapolate Moore’s law we
“hit the wall” with CMOS about
2015 and although we don’t know
which technology will replace it.
Mid-term issues
In many areas of technology, once
we hit an area of concern, we can
develop a workaround. Hence
clock speed, which was the measure
many followed as the measure
of processing capability, has been
replaced in some devices by distributed
processing with two processors
placed on the same chip.
This gets the job done without reduced
heat penalty and gives us a
breathing space, many upper end
processors generate between 100W
and 200W, but the heat issue has
not gone away. Several unusual
properties of nanoscale materials,
