US Patent 7419887 - Laser assisted nanodeposition

This patent teaches a new type of nanofabrication process involving the focusing of a laser beam width to nanometer dimensions and using the laser to fuse nanoparticles deposited via a nanosize pore. Claim 1 reads:

1. The process of forming a nano structure on a substrate, comprising:

suspending nano particles in a suspension fluid;

applying a pressure to the suspension fluid for forcing the nano particles through a nano size pore onto the substrate;

directing a micrometer size laser beam through a concentrator for forming a nanometer size laser beam; and

directing the nano size laser beam onto the deposited nano particles on the substrate.
