Nanomanufacturing

Nanomanufacturing involves two main approaches: bottom-up fabrication which builds products from atomic and molecular components, and top-down fabrication which reduces large materials into nanoscale pieces. Some key nanomanufacturing techniques include dip-pen lithography which writes chemical patterns like an ink pen, self-assembly where components join without direction to form organized structures, and molecular beam epitaxy which deposits highly controlled thin films.

Nanomanufacturing

1. Bottom-up fabrication
 Manufactures
products by
building them up
from atomic – and
molecular scale
components.
2. Top-down fabrication
 It trims down large
pieces of materials
into nanoscale.

 Dip-pen lithography
 A method in which the tip of an atomic force microscope is “dipped”
into a chemical fluid and then utilized to “write” on a surface, like an
old-fashioned ink pen onto paper.
 Self-assembly
 Depicts an approach wherein a set of components join together to mold
an organized structure in the absence of an outside direction.

 Chemical vapor deposition


 A procedure wherein chemicals act in response to form very pure, high
performance films.
 Process from left to right.
 Nanoimprint lithography
-A method of generating nanoscale attributes by stamping or printing
them into a surface.

 Molecular beam
epitaxy
- A manner of depositing extremely controlled thin films.
 Roll-to roll processing
- A high-volume practice for constructing nanoscale devices on a roll of
ultrathin plastic or metal.

 Atomic layer epitaxy


- A means for laying down one-atomic-thick layers on a surface.
