Nanofabrication

By: Julian & Joris

Table of contents:

- What is nanofabrication?

- The nanoscale

- How does nanofabrication work?

- How is nanofabrication used?

- The future of nanofabrication

What is nanofabrication?

- Creating structures 

on the nanoscale

- New materials

- Very small complex 

structures

- Standard since 1970

- Rapidly changing

Try to name an example of something on the nanoscale

The nanoscale

- Very small

- Different material properties

Which do think is the smallest?

1. Nanotechnology
2. Bacteria
3. Human hair
4. Cancer cell

Comparison between our scale and the nanoscale

What is the difference between manufacturing on the nanoscale and on our scale?

1. The kinds of microscopes used
2. The environment in which manufacturing is possible
3. The room in which manufacturing is done
4. All of the above

How does nanofabrication work?

- Different scale so also different manufacturing processes

- Cleanrooms

- Electron microscopes

- Vacuum systems

How does nanofabrication work?

- Two main ways: bottom-up & top-down

How does nanofabrication work?

Bottom-up

Thin film deposition:

- Thermal evaporation

- Electron-beam evaporation

- Sputtering

Atomic layer deposition:

- Chemical vapor deposition

Top-down 

Lithography:

- Photolithography

- Electron-beam lithography

- Ion beam lithography

Etching:

- Wet etching

- Dry etching

How is nanofabrication used?

Electronics:

- Faster

- Smaller

- More efficient

Energy:

- Kyoto university

- Double the amount of solar energy

- Cheaper

Biomedicine:

- Early diagnosis

- Better treatment

The future of nanofabrication

Biomedicines:

- Guided pills

- More direct medicine

- Fewer side effects

Electronics:

- Smaller and smaller

- More powerful

- High density microprocessors and memory chips

- Bits of data stored on single atoms

- Nanobots
