Abstract: The disclosure relates to the manufacture of semiconductor devices, especially to methods and processing assemblies for forming a patterned structure on a substrate. The methods comprise providing the substrate comprising a first structure into a reaction chamber, wherein a surface of the first structure comprises a first material and the substrate comprises a second material, and selectively depositing a conformal passivation layer on the first material relative to the second material to cover the first structure, and selectively depositing an etch-stop layer on the second material relative to the passivation layer. In some embodiments, a multiple patterning or a tone reversal of a pattern may be performed using the methods and deposition assemblies of the disclosure.

IPC: C23C16/04

Abstract: The disclosure relates to methods, processing assemblies, reactants and vapor deposition vessels for selective vapor-phase deposition of inhibitor material on a substrate comprising two surfaces. In some embodiments of the disclosure, the inhibition material is deposited on the first surface of the substrate, whereas substantially no inhibitor material is deposited on the second surface of the substrate. The inhibitor material is formed by contacting the substrate with a vapor-phase inhibitor reactant comprising a silicon atom bonded to an oxygen atom and to a second atom selected from nitrogen and halogens.

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.
