An old wisdom: Dip-Pen technology On Jan, 1999 More than 4000 years ago… Pen Ink Patterns Substrate Dip-pen lithography is straightforward. Any draw back?
Dip-pen lithography ? E-beam lithography Ion-beam lithography Serial replication Lithography: Photolithography Contact printing Nanoimprint lithography Parallel replication Advantage: Time effective, economic
The secret: multi-identical-pens ~11,000,000 pens
Second Advantage: size controllable Chinese calligraphy Pattern size controlled by the pressure on polymer.
Massive production of patterns 2008 Beijing Olympic logo The total time required is less than 40 mins.
