Abstract: A process of forming an electronic device can include patterning a semiconductor layer to define an opening extending to an insulating layer, wherein the insulating layer lies between a substrate and the semiconductor layer. After patterning the semiconductor layer, the opening can have a bottom, and the semiconductor layer can have a sidewall and a surface. The surface can be spaced apart from the insulating layer, and the sidewall can extend from the surface towards the insulating layer. The process can also include depositing a nitride layer within the opening, wherein depositing is performed using a PECVD technique. The process can further include densifying the nitride layer. The process can still further include removing a part of the nitride layer, wherein a remaining portion of the nitride layer can lie within the opening and be spaced apart from the surface.
