Abstract:
A method for shallow etching a substrate surface forms a shallow modified substrate layer overlying unmodified substrate using an accelerated neutral beam and etches the modified layer, stopping at the unmodified substrate beneath, producing controlled shallow etched substrate surfaces.

Claim (Index 1):
A method for controlled shallow etching of a surface of a substrate comprising the steps of:\n providing a reduced pressure chamber; forming a gas cluster ion beam comprising gas cluster ions within the reduced pressure chamber; accelerating the gas cluster ions to form an accelerated gas cluster ion beam along a beam path within the reduced pressure chamber; promoting fragmentation and/or dissociation of at least a portion of the accelerated gas cluster ions along the beam path; removing charged particles from the beam path to form an accelerated neutral beam along the beam path in the reduced pressure chamber; holding the substrate in the beam path; treating a portion of a surface of the substrate by irradiating it with the accelerated neutral beam to form a shallow modified layer on the irradiated portion of the surface, the shallow modified layer, overlying unmodified substrate beneath; etching the surface having the shallow modified layer to preferentially remove material in the shallow modified layer on the surface and wherein the etching stops at the unmodified substrate beneath.
