Abstract:
1. A method of fabricating a conformal film on a substrate, the method comprising: heating the substrate to a temperature sufficiently low so that precursor adsorbed on the substrate is not thermally dissociated; depositing a film of predetermined thickness on the substrate by performing a predetermined number of atomic layer deposition cycles in a processing chamber, each atomic layer deposition cycle comprising: dosing the substrate with a precursor to establish a monolayer of the precursor on the substrate; and wherein the film, as deposited, generally has a tensile intrinsic stress; and annealing the substrate and the film after a predetermined number of atomic layer deposition cycles to change the intrinsic stress in the film from tensile to compressive.
