A robust ICEFILL method to provide void free trench fill for logic and memory applications

Methods of filling a gap with a dielectric material including using an inhibition plasma during deposition. The inhibition plasma increases a nucleation barrier of the deposited film. The inhibition plasma selectively interacts near the top of the feature, inhibiting deposition at the top of the fea...

Beschreibung
Zusammenfassung:	Methods of filling a gap with a dielectric material including using an inhibition plasma during deposition. The inhibition plasma increases a nucleation barrier of the deposited film. The inhibition plasma selectively interacts near the top of the feature, inhibiting deposition at the top of the feature compared to the bottom of the feature, enhancing bottom-up fill.
