Abstract: The disclosure relates to methods and processing assemblies selectively depositing metal oxide by cyclic vapor deposition techniques. Such methods may be used for, for example, processing semiconductor substrates. More particularly, the disclosure relates to methods and assemblies for selectively depositing a metal oxide layer. Various embodiments of the current disclosure relate to selective deposition of metal oxide layers, such as dielectric layers, etch stop layers and threshold voltage shifting layers. In particular, the disclosure relates to the deposition of metal oxide layers, such as yttrium oxide (Y2O3), and doped metal oxide layers, such as yttrium-doped aluminum oxide (AlYOx) by cyclic vapor deposition processes.

Abstract: The disclosure relates to methods of selectively depositing an oxide material layer on a first surface of a semiconductor substrate relative to a second surface of the same substrate, to semiconductor processing assemblies, as well as to oxide material layers, structures and devices comprising an oxide material layer deposited according to the current disclosure. In the method, an oxide material layer is selectively deposited using a first precursor and an oxygen precursor. The second surface may be passivated against deposition of oxide material.

Abstract: The current disclosure relates to methods and assemblies for selectively etching a material from a first surface of a substrate relative to a second surface of the same substrate. The second surface of the substrate is covered by an organic polymer layer and the first surface is etched by a reactive species generated from NF3-containing plasma. The current disclosure further relates to semiconductor structures and devices formed by using the methods or assemblies of the disclosure.
