Abstract:
Thermal atomic layer etching processes are disclosed. In some embodiments, the methods comprise at least one etch cycle in which the substrate is alternately and sequentially exposed to a first vapor phase halide reactant and a second vapor halide reactant. In some embodiments, the first reactant may comprise an organic halide compound. During the thermal ALE cycle, the substrate is not contacted with a plasma reactant.

Claim (Index 1):
A method of etching a film on a substrate in a reaction chamber, the method comprising one or more etching cycles, each etching cycle comprising:\n exposing the substrate to at least two vapor-phase halide reactants; subsequently exposing the substrate to a third, different vapor-phase reactant, such that volatile species comprising one or more atoms from the film are formed; and removing volatile species from the reaction chamber, wherein the substrate is not contacted with a plasma reactant during the etching cycle.
