2. An old wisdom: Dip-Pen technology
More than 4000 years ago…
On Jan, 1999
Pen
Ink
Patterns
Substrate
Dip-pen lithography is straightforward. Any draw back?

3. ? E-beam lithography Ion-beam lithography Serial replication
Dip-pen lithography ?
Lithography:
Photolithography
Contact printing
Nanoimprint lithography
Parallel replication
Advantage: Time effective, economic

4. The secret: multi-identical-pens

5. Second Advantage: size controllable
Chinese calligraphy
Pattern size controlled by the pressure on polymer.

6. Massive production of patterns
