Abstract:
Embodiments involve patterned mask formation. In one embodiment, a method involves depositing a CVD film over a semiconductor wafer; exposing the CVD film to e-beam or UV radiation, forming a pattern in the CVD film; and etching the pattern in the CVD film, forming features in areas not exposed to the e-beam or UV radiation. In one embodiment, a method involves depositing a CVD film over a semiconductor wafer; depositing a thin photo-sensitive CVD hardmask film over the CVD film; exposing the thin photo-sensitive CVD hardmask film to e-beam or UV radiation, forming a pattern in the thin photo-sensitive CVD hardmask film; etching the pattern in the thin photo-sensitive CVD hardmask film; etching the pattern into the CVD film through the patterned thin photo-sensitive CVD hardmask film; and removing the patterned thin photo-sensitive CVD hardmask film.
Abstract:
Embodiments include systems, apparatuses, and methods of thin metal-organic film deposition with inkjet printheads. A method of depositing a metal-organic thin film over a substrate includes introducing chemical precursors into one or more piezoelectric printheads. The chemical precursors including a metallic compound and a reactive liquid or gas. The method further includes dispensing droplets or a stream of the chemical precursors with the piezoelectric printheads onto a surface of the substrate supported by a stage in a vacuum chamber.
Abstract:
Methods and process chambers for etching of low-k and other dielectric films are described. For example, a method includes modifying portions of the low-k dielectric layer with a plasma process. The modified portions of the low-k dielectric layer are etched selectively over a mask layer and unmodified portions of the low-k dielectric layer. Etch chambers having multiple chamber regions for alternately generating distinct plasmas are described. In embodiments, a first charge coupled plasma source is provided to generate an ion flux to a workpiece in one operational mode, while a secondary plasma source is provided to provide reactive species flux without significant ion flux to the workpiece in another operational mode. A controller operates to cycle the operational modes repeatedly over time to remove a desired cumulative amount of the dielectric material.
