This invention relates to a plasma treating method and apparatus therefor. The plasma treating method comprises rendering a gas having a critical potential plasmic under a reduced pressure and changing an acceleration voltage for accelerating ions in the plasma towards a sample interposing the critical potential. The plasma treating apparatus comprises means for rendering a gas having a critical potential plasmic under a reduced pressure and means for changing an acceleration voltage for accelerating ions in the plasma towards a sample interposing the critical potential. According to the present invention, the etching step and the film formation step can be carried out alternately and the plasma treating time can be shortened.
摘要:
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.

摘要:
The present invention relates to a microwave plasma processing apparatus, suited for generating a plasma by using microwaves, and a processing method. Microwaves propagated through a circular waveguide are tuned in the space thereof by a microwave tuner that is installed to match the impedance, and are introduced in a uniform and most efficient state into a discharge block having a plasma-resistant inner surface that is enlarged in a tapered form through a microwave introduction window. Then, a processing gas controlled to a predetermined pressure by a gas supplying structure and gas evacuating structure is turned into a plasma which is more uniform and is more dense by interaction of a microwave electric field that is efficiently introduced and a magnetic field produced by a solenoid coil.

摘要:
A sample is plasma etched and then treated with a second plasma to remove residual corrosive compounds formed by the etching plasma. Removal of the residual corrosive compounds and prevention of corrosion is improved by washing 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 the surface, the step of washing is followed by drying the sample.

Disclosed is apparatus for treating samples, and a method of using the apparatus. The apparatus includes processing apparatus (a) for treating the samples (e.g., plasma etching apparatus, the samples being selectively etched through use of a resist mask), (b) for removing (ashing) the resist mask, (c) for wet-processing of the samples and (d) for dry-processing the samples. Samples are passed sequentially from a supply cassette (containing a plurality of samples) to the plasma etching apparatus, through the other apparatus and to a discharge cassette (which can hold a plurality of the samples). At least two of the samples can be processed simultaneously in a path from (and including), the plasma etching apparatus to (and including) the wet-processing structure.
