摘要:
A sample treating method and apparatus for treating a sample such as a semiconductor element substrate or the like, by etching and anticorrosion-treatment, uses an anticorrosion gas plasma to remove adhered matters formed by the etching of the sample. The anticorrosion gas comprises halogen gas or inert gas. Wet-type anticorrosion treatment is not required, enabling the throughput to be improved in treating the samples. Both etching and anticorrosion treatment may take place in the same chamber (90). Passivation treatmemt, e.g. by oxygen plasma or ozone, may take place subsequently in a separate chamber (91).

摘要:
A method and apparatus for processing a sample comprises etching the sample by means (10; 11-14) of an etching plasma, and then treating the sample by means (20-21) of a second plasma, to remove residual corrosive compounds formed by the etching plasma. Removal of the residual corrosive compounds and prevention of corrosion is much improved by contacting (30, 31) the surface of the sample after the second plasma treatment with at least one liquid in order to effect at least one of (a) removal of the residual corrosive compounds and (b) passivation of said surface exposed by steps, and drying (41) the sample.
摘要:
A post-etch treatment method is provided which is capable of imparting high corrosion prevention performance to 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 an oxygen component, and the resist formed on the aluminum-containing wiring material is reacted with oxygen and is removed. Further, a plasma is generated using a gas having a 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).
