摘要:
A heat treatment apparatus for heat-treating a silicon substrate includes a mounting table for mounting and heating the silicon substrate thereon, wherein a cover made of any of silicon, silicon carbide, and aluminum nitride is placed on an upper surface of the mounting table. By covering the upper surface of the mounting table by the cover made of silicon or the like, metal contamination of the lower surface of the silicon substrate is suppressed.

An etching method includes preparing a target object such that a first oxide film made of silicon oxide containing at least one of B and P is formed on a substrate, a second oxide film made of silicon oxide containing neither of B and P is formed on the first oxide film, and a contact portion is present below an interface between the first oxide film and the second oxide film. The etching method further includes etching the second oxide film and the first oxide film, thereby forming a hole reaching the contact portion, and etching the first oxide film by a dry process using a gas containing HF, thereby expanding a portion of the hole adjacent to an upper side of the contact portion and inside the first oxide film.

[Object] To provide a processing method capable of removing an oxide film adhering on a Si layer from the Si layer without adversely affecting parts other than the oxide film and capable of surely forming a SiGe layer with good film quality without roughening the crystal structure of a surface of the Si layer from which the oxide film has been removed, and to provide a recording medium.[Means for Solving the Problems] A processing method for removing an oxide film growing on a surface of a Si layer, and forming a SiGe layer on the surface of the exposed Si layer includes: supplying gas containing a halogen element and basic gas to the surface of the Si layer, and causing the oxide film growing on the surface of the Si layer to chemically react with the gas containing the halogen element and the basic gas to turn the oxide film into a reaction product; removing the reaction product by heating; and thereafter forming the SiGe layer on the surface of the exposed Si layer.

A substrate stage for mounting a substrate thereon includes a peripheral stage member on which a peripheral substrate portion of the substrate may be mounted, the peripheral substrate portion controlling a temperature of the peripheral substrate portion, a central stage member on which a central substrate portion of the substrate may be mounted, the central substrate portion controlling a temperature of the central substrate portion, and a support base that supports the peripheral stage member and the central stage member. A gap is formed between the peripheral stage member and the central stage member to keep the peripheral stage member and the central stage member from coming in contact with each other.

The present invention is a method of manufacturing a semiconductor device from a layered body including: a semiconductor substrate; a high dielectric film formed on the semiconductor substrate; and an SiC-based film formed on a position upper than the high dielectric film, the SiC-based film having an anti-reflective function and a hardmask function. The present invention comprises a plasma-processing step for plasma-processing the SiC-based film and the high dielectric film to modify the SiC-based film and the high dielectric film by an action of a plasma; and a cleaning step for wet-cleaning the SiC-based film and the high dielectric film modified in the plasma-processing step to collectively remove the SiC-based film and the high dielectric film.
