Abstract: This invention relates to a method for etching an organic insulating film used in the production of semiconductor devices. A sample to be etched on which a low dielectric constant organic insulating film is formed is etched by generating a plasma from hydrogen gas and nitrogen gas or ammonia gas, and controlling the gas flow rate and pressure so that the light emission spectral intensity ratio of hydrogen atom and cyan molecule in the plasma comes to a prescribed value. By this method, a low dielectric constant organic insulating film as an insulating film between layers can be etched without using any etch stop layer so that bottom surfaces of trenches and holes for electrical wiring become flat.

Abstract: A post-etch treatment method capable of imparting high corrosion prevention performance to the aluminum-containing wiring films. The sample of aluminum-containing wiring material that is etched using the halogen-type gas is treated with the plasma of a gas that has the oxygen component, and the resist formed on the aluminum-containing wiring material is reacted with oxygen and is removed. Further, the plasma is generated using a gas having the hydrogen component or this gas is liquefied into droplets thereof on the sample surface, so that halogen components (Cl, Br, etc.) adhered to the aluminum-containing wiring material through the etching treatment are reacted with hydrogen and are effectively removed in the form of hydrogen chloride (HCl) or hydrogen bromide (HBr). This makes it possible to obtain the aluminum-containing wiring material having high corrosion prevention performance.

Abstract: A plasma-etching apparatus is capable of etching a film of a workpiece with a plasma produced in an evacuated etching chamber at a high etch selectivity relative to an underlying film or a resist film. The frequency of a RF bias voltage applied to a sample table by a RF power source is adjusted so that the ion energy of the plasma is distributed in a saddle-peak energy distribution pattern. The film is etched at a high etch selectivity relative to a material having a threshold ion energy.
