According to a specific embodiment of the present invention, a mask-less
lithography method and apparatus is provided. The apparatus includes an
integrated write head on a slider with an air bearing that creates a lift
force that allows that write head to fly over a spinning wafer substrate
in nanometer distance without physical contact. The short distance
between the write head and substrate prevents the light from diffracting.
As a result, micro and nanometer structures can be patterned without
being limited by light diffraction in conventional lithography methods.
