The first via group has at least two first line vias extending in a first direction, and the second via group has at least two second line vias extending in a second direction.

A microwave is radiated into a processing chamber (1) from a planar antenna member of an antenna (7) through a dielectric plate (6). With this, a C₅F₈ gas supplied into the processing chamber (1) from a gas supply member (3) is changed (activated) into a plasma so as to form a fluorine-containing carbon film of a certain thickness on a semiconductor wafer (W). Each time a film forming process of forming a film on one wafer is carried out, a cleaning process and a pre-coating process are carried out. In the cleaning process, the inside of the processing chamber is cleaned with a plasma of an oxygen gas and a hydrogen gas. In the pre-coating process, the C₅F₈ gas is changed into a plasma, and a pre-coat film of fluorine-containing carbon thinner than the fluorine-containing carbon film formed in the film forming process is formed.

In a method of fabricating an SOI wafer, an oxide film is formed on the surface of at least one of two silicon wafers; hydrogen ions or rare gas ions are implanted into the upper surface of one of the two silicon wafers in order to form a fine bubble layer (enclosed layer) within the wafer; the ion-implanted silicon wafer is superposed on the other silicon wafer such that the ion-implanted surface comes into close contact with the surface of the other silicon wafer via the oxide film; heat treatment is performed in order to delaminate a portion of the ion-implanted wafer while the fine bubble layer is used as a delaminating plane, in order to form a thin film to thereby obtain an SOI wafer. In the method, a defect layer at the delaminated surface of the thus-obtained SOI wafer is removed to a depth of 200 nm or more through vapor-phase etching, and then mirror polishing is performed. Therefore, the obtained SOI wafer has an extremely low level of defects and a high thickness uniformity.

In the lithographic multilayer resist process, a material comprising a copolymer of a hydroxy-containing vinylnaphthalene with hydroxy-free olefins is useful in forming a resist undercoat. The undercoat-forming material has a high transparency and optimum values of n and k so that it functions as an antireflective coating during short-wavelength exposure, and has etching resistance during substrate processing by etching.

A process gas to a reactor volume of a semiconductor processing reactor is provided through gas injector ports of a gas ring. The process gas flows horizontally from the gas injector ports across a principal surface of a rotating susceptor to exhaust ports of the gas ring. The spent process gas is removed from the reactor volume through the exhaust ports.
