    Abstract: A plasma processing operation uses a gas mixture of N2 and H2 to both remove a photoresist film and treat a low-k dielectric material. The plasma processing operation prevents degradation of the low-k material by forming a protective layer on the low-k dielectric material. Carbon from the photoresist layer is activated and caused to complex with the low-k dielectric, maintaining a suitably high carbon content and a suitably low dielectric constant. The plasma processing operation uses a gas mixture with H2 constituting at least 10%, by volume, of the gas mixture.

    Abstract: A method is described for selectively etching a high k dielectric layer that is preferably a hafnium or zirconium oxide, silicate, nitride, or oxynitride with a selectivity of greater than 2:1 relative to silicon oxide, polysilicon, or silicon. The plasma etch chemistry is comprised of one or more halogen containing gases such as CF4, CHF3, CH2F2, CH3F, C4F8, C4F6, C5F6, BCl3, Br2, HF, HCl, HBr, HI, and NF3 and leaves no etch residues. An inert gas or an inert gas and oxidant gas may be added to the halogen containing gas. In one embodiment, a high k gate dielectric layer is removed on portions of an active area in a MOS transistor. Alternatively, the high k dielectric layer is used in a capacitor between two conducting layers and is selectively removed from portions of an ILD layer.
