Claim Text:
1. A deposition method to deposit a conformal film on a non-planar surface having at least one sidewall and a planar surface of a substrate, the conformal film comprised of a plurality of layers, the deposition method comprising: depositing a first layer having at least one sidewall and a planar surface that is one to two nanometers thick over the non-planar surface of the substrate along the at least one sidewall and the planar surface of the substrate from a first plurality of precursors on the substrate, the deposition being not self-limiting; first plasma treating and modifying the first layer along the at least one sidewall and the planar surface of the first layer using a second plurality of precursors to incorporate a material into the first layer; depositing a second layer having at least one sidewall and a planar surface that is one to two nanometers thick from a third plurality of precursors; second plasma treating and modifying the second layer along the sidewall and the planar surface of the second layer using a fourth plurality of precursors to incorporate a material into the second layer; and repeating depositing the first layer, first plasma treating, depositing the second layer, and second plasma treating one to nine times to form the conformal film, wherein the conformal film conforms to the non-planar surface, and wherein the first plurality of precursors has a different composition than the third plurality of precursors such that the conformal film comprises a multi-layer film or a nanolaminate film.
