A semiconductor device includes a gate insulating film formed on a silicon substrate, a gate electrode formed on the gate insulating film, and an electrical insulating film formed on the gate electrode. The electrical insulating film includes a N—H bond and substantially no Si—H bond. The electrical insulating film is formed by using tetrachlorosilane (SiCl4) that contains no hydrogen (H) as a source gas for a silicon nitride film. Thus, the semiconductor device can suppress residual hydrogen in the gate insulating film and prevent interface defects of the gate insulating film, a shift in the threshold voltage of a transistor, and the degradation of an on-state current. A method for manufacturing the semiconductor device also is provided.

摘要:
In a method for fabricating a semiconductor device, a first electrode made of polycrystalline silicon is subjected to first plasma containing oxygen, thereby forming a silicon oxide film in the surface of the first electrode. Then, the first electrode in which the silicon oxide film has been formed is subjected to second plasma containing nitrogen, thereby changing the silicon oxide film into a silicon oxynitride film. Subsequently, a capacitive insulating film made of a metal oxide is formed on the first electrode in which the silicon oxynitride film has been formed. Thereafter, the capacitive insulating film is subjected to third plasma containing oxygen, thereby supplying oxygen to the capacitive insulating film. Thereafter, thermal processing is performed in an oxidizing atmosphere on the capacitive insulating film to which oxygen has been supplied, and then a second electrode is formed on the capacitive insulating film.

A wafer is held on a pin chuck, and thereafter a design pattern is transferred to the principal surface of the wafer by exposing an exposure light, which passes through a mask having the design pattern, onto the principal surface of the held wafer. The underlying surface of the wafer has irregularities with cross-sectional cycle lengths of 300 μm or more and depressions with opening diameters of 100 μm or less, and is formed such that an arithmetic mean of depths of the irregularities and depths of the depressions is 200 nm or less. The differences in distance between a focal position of the exposure light and the principal surface of the wafer held on the pin chuck are set at 50% or less of a design rule.
