Nanotechnology in Computer Processing
Moore’s Law
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
NANO TRANSISTOR
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
Nanotechnology in Memory and Storage
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
nanotechnoloy
,1000GB of memory
can fit on the head of
this pin. 1000 GB is
1 Terabyte.
Nanotechnology in Displays
Nanotubes are small enough that they cannot be seen, so they can be great conductors to be used as transparent contacts.
These layers contain transparent electrodes
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?
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.
This is a scanning electron Microscope image of an 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.
