    摘要： In order to etch an object to be processed, such as a semiconductor wafer, the object to be processed is placed in a vacuum processing chamber, an etching gas is introduced into the vacuum processing chamber, and electrical power is applied to a pair of electrodes within the vacuum processing chamber by a high-frequency electrical power source. A mixed gas of carbon monoxide and a gas which does not contain hydrogen and which contains at least one element from the group IV elements and at least one element from group VII elements is used as the etching gas. A halogenated carbon gas, typically a fluorocarbon such as C.sub.4 F.sub.8, is used as the gas containing elements from the group IV and group VII elements. The concentration of carbon monoxide in the etching gas could be 50% or more. At least approximately 86% of an inert gas, such as argon, xenon, krypton, or N.sub.2 and O.sub.2 could be added to the etching gas. Use of the above etching gas enables a high etching selectivity and prevents the formation of fences.

    摘要： A vacuum chamber contains a first electrode for supporting a wafer, and a second electrode opposing the first electrode. A supply system and an exhaustion system are connected to the vacuum chamber. The system supplies a reactive gas into the chamber, and the system exhaust the used gas from the chamber. A radio-frequency power supply is connected to the first electrode, for supplying power between the electrodes to generate an electric field E. An annular magnet assembly is provided around the chamber, for generating a magnetic field B which has a central plane intersecting with the electric field E. The magnet assembly has a plurality of magnet elements which have different magnetization axes in the central plane of the magnetic field. Electrons drift due to a force resulting from an outer product (E.times.B) of the electric field E and the magnetic field B. The central plane of the magnetic field B is shifted upwards from the target surface of the wafer, such that the magnetic force lines of the magnetic field intersect with the target surface of the substrate.

    摘要： A plasma etching method is provided to perform a plasma etching on a silicon oxide film or a silicon nitride film formed below an amorphous carbon film by using a pattern of the amorphous carbon film as a final mask in a multilayer mask including a photoresist layer having a predetermined pattern, an organic bottom anti-reflection coating (BARC) film formed below the photoresist layer, an SiON film formed below the BARC film, and the amorphous carbon film formed below the SiON film. An initial mask used at the time when the plasma etching of the silicon oxide film or the silicon nitride film is started is under a state in which the SiON film remains on the amorphous carbon film and a ratio of a film thickness of the amorphous carbon film to a film thickness of the residual SiON film is smaller than or equal to about 14.

    摘要： In a first step and a thirst step, etching gases are used which contain fluorocarbon gases having C/F atom number ratios higher than that in a second step. A hole is formed to a midpoint in a silicon oxide film in the first step, the hole is formed until a base SiN film begins to be exposed or immediately before it is exposed in the second step, and overetching is performed in the third step. This enables even a hole having a fine diameter and a high aspect ratio to be formed in an excellent shape.
