    摘要: A manufacturing method of a semiconductor device having a trench is provided to form, at a corner portion of the trench, an oxide film which is greater in thickness and smaller in stress than at other portions. When the trench formed in the semiconductor substrate is oxidized, it is oxidized in an oxygen environment containing dichloroethylene at a predetermined weight percent to allow the formation of an oxide film having a greater thickness at the corner portion of the trench than thickness at other portions, whereby the semiconductor device improving dielectric breakdown characteristics can be obtained.

    摘要: After a first gate oxide film (302) is formed on a substrate (301), a nitride layer (303) is formed by a first oxynitriding process. The first gate oxide film is selectively removed from a thinner film part area of the substrate. A second gate oxide film forming process forms a second gate oxide film (305A) in the thinner film part area and a third gate oxide film (305B) in a thicker film part area. By executing second oxynitriding process, nitride layers (306A and 306B) are formed at the thinner and the thicker part areas.

    摘要: A method for forming an oxide film includes a first in-situ steam generation (ISSG) process using a 1%-H2 concentration in the ambient gas and a subsequent second ISSG process using a 5%-H2 concentration in the ambient gas, wherein the second ISSG process compensates an in-plane thickness distribution of the film formed by the first ISSG process. The time length for the first and second ISSG steps is determined based on a desired film thickness, a time length dependency of a film formed by the second ISSG process, and the oxidation rate of the first and second ISSG processes.

    摘要: A deletion in the end region of the long arm of a Chromosome 9 is efficiently detected. A genetic testing kit of bladder cancer according to the present invention includes a primer allowing for efficient amplification of a region containing a site of genetic polymorphism present in the ABO blood group genes of Chromosome 9. In the site of genetic polymorphism present in the ABO blood group genes, the frequency of heterozygote (heterozygosity) in the population is extremely high. Therefore, by detecting LOH using a polymorphic site present in the ABO blood group genes, it is possible to reliably detect a deletion near the polymorphic site, in other words, a deletion near the end of the long arm of Chromosome 9.
