US Patent 7465595 - AFM manufacture of quantum dot electronics

a href="http://www.freepatentsonline.com/7465595.html"http://www.freepatentsonline.com/7465595.html/abr /br /This patent from Fujitsu teaches using a href="http://en.wikipedia.org/wiki/Atomic_force_microscope"atomic force microscopes/a to form a href="http://en.wikipedia.org/wiki/Quantum_dot"quantum dot/a electronic structures. With high density AFM arrays this type of technology could eventually enable production of a href="http://en.wikipedia.org/wiki/Quantum_computer"quantum computers/a. Claim 1 reads:br /br /1. A manufacturing method of a quantum device, comprising the steps of:br /br /bringing a tip of an atomic force microscope to which a negative bias is applied into contact with a surface of a semiconductor substrate to form a ring-shaped oxide film on the surface of the semiconductor substrate in an atmosphere containing water;br /br /forming a ring-shaped groove in the surface of the semiconductor substrate by removing the oxide film; andbr /br /growing a semiconductor film in the groove.
