    摘要: Embodiments described herein include methods of forming metal silicide layers using a diffusionless annealing process. In one embodiment a method for forming a metal silicide material on a substrate is provided. The method comprises depositing a metal material over a silicon containing surface of a substrate, depositing a metal nitride material over the metal material, depositing a metallic contact material over the metal nitride material, and exposing the substrate to a diffusionless annealing process to form a metal silicide material. The short time-frame of the diffusionless annealing process reduces the time for the diffusion of nitrogen to the silicon containing interface to form silicon nitride thus minimizing the interfacial resistance.

    摘要: A method for processing a semiconductor substrate in a chamber includes forming a silicon oxynitride film using a two-step anneal process. The first anneal step includes annealing the silicon oxynitride film in the presence of an oxidizing gas that has a partial pressure of about 1 to about 100 mTorr, and the second anneal step includes annealing the silicon oxynitride film with oxygen gas that has a flow rate of about 1 slm. The first anneal step is performed at a higher chamber temperature and higher chamber pressure than the second anneal step.

    摘要: In a method for determining the nitrogen concentration in a film of nitrided oxide material formed over a semiconductor wafer during fabrication of a semiconductor device an optical property of the film of nitrided oxide material is determined. The determined optical property is used to determine the nitrogen concentration in the film of nitrided oxide material. In one embodiment the optical property, e.g., extinction coefficient, k, is correlated to the nitrogen concentration measured by secondary ion mass spectroscopy. In a method of making a semiconductor device a film of nitrided oxide material is formed over a plurality of semiconductor wafers in a fab. The nitrogen concentration in the film of nitrided oxide material is monitored by periodically subjecting one of the wafers to an in-line test in the fab.
