Moore’s Law
Updated September 2011
Moore’s Law
describes a trend
of technology. It
states that the
number of
transistors that
can be put on a
single chip will
double every two
years.

Instead of making
transistor components and
assembling them on a
board, nanoscale
transistors are grown
together on a silicon wafer.
They look much different
from the traditional
transistors.

•
The human brain has about 100 billion
neurons.
•
Each neuron has thousands of synapses.
•
The newest processors have only two
billion transistors.

Because of
nanotechnology,
the speed of
computers has
increased while
the price of

computing has
decreased.

This is a 2 gigabyte
hard drive. It
weighs about 70
pounds. It was first
used in the 1980s.
Its cost at that time
ranged from
$80,000 to
$140,000.

Current research
shows that by
using
nanotechnology,

1000 GB of
memory can fit
on the head of
this pin. 1000 GB
is 1 Terabyte.

Nanotubes are small
enough that they
cannot be seen, so
they can be great
conductors to be
used as transparent
contacts.

Carbon nanotubes
on a glass or
plastic sheet
allow
manufacturers to
make clear
conductive panels
for displays that
are extremely
thin.

Nanotechnology
in Circuitry
How do we see these circuits?
Updated September 2011
To see the
circuitry,
researchers use
an electron
microscope or
an atomic force
microscope. This
image shows
different levels of
a circuit.

In the Nano
Electronics
Activity, you will
download the
virtual
microscope from
the University of
Illinois website. It
allows you to

explore samples
with an SEM and
AFM.

accelerometer.

You can use the
controls to zoom
in, pan, and take
measurements.

Choose the
integrated circuit.
Change the color
scheme to HSV.
Use the scroll
wheel on the
mouse to zoom in
and out. Toggle
the AFM and draw
a box on the chip
to show the 3D
view of that part
of the circuit.

Drag the scale tool
in the locations on
the chip to record
the measurements.
Drag the height tool
between locations
on the chip to
record the
measurements.

This module is one of a series designed to introduce faculty and high school
students to the basic concepts of nanotechnology. Each module includes a
PowerPoint presentation, discussion questions, and hands-on activities, when
applicable.

The series was funded in part by:

The National Science Foundation
Grant DUE-0702976
and the
Oklahoma Nanotechnology Education Initiative

Any opinions, findings and conclusions or recommendations expressed in the
material are those of the author and do not necessarily reflect the views of the
