Abstract: Provided is a plasma enhanced atomic layer deposition (PEALD) process for depositing etch-resistant SiOCN films. These films provide improved growth rate, improved step coverage and excellent etch resistance to wet etchants and post-deposition plasma treatments containing O2 and NH3 co-reactants. This PEALD process relies on one or more precursors reacting in tandem with the plasma exposure to deposit the etch-resistant thin-films of SiOCN. The films display excellent resistance to wet etching with dilute aqueous HF solutions, both after deposition and after post-deposition plasma treatment(s). Accordingly, these films are expected to display excellent stability towards post-deposition fabrication steps utilized during device manufacturing and build.

Abstract: Disclosed herein is a process to functionalise a hydrosilane, the process comprising the steps of: (a) providing a hydrosilane of formula (I); and (b) photochemically reacting the hydrosilane of formula (I) in the presence of a solvent, neutral Eosin Y, a reagent and, optionally, an additive, for a period of time in the presence of light and at a suitable temperature to provide a compound of formula (II). This functionalization enabled by Eosin Y photocatalysis allowed us to achieve modular and versatile stepwise decoration of a silicon atom from a di- or trihydrosilane for the synthesis of multisubstituted organosilanes.
