Semiconductor devices with dual nature capping/ARC layers on fluorine doped silica glass inter-layer dielectrics and method of forming capping/ARC layers
Semiconductor devices with dual nature capping/ARC layers on fluorine doped silica glass inter-layer dielectrics and method of forming capping/ARC layers
Degradation of fluorine-doped silica glass low-k inter-layer dielectrics during fabrication is significantly reduced and resolution of submicron features is improved by the formation of dual nature capping/ARC layers on inter-layer dielectric films. The capping/ARC layer is formed in-situ on a fluorine-doped silica glass inter-layer dielectric. The in-situ formation of the capping/ARC layer provides a strongly adhered capping/ARC layer, formed with fewer processing steps than conventional capping and ARC layers.
