Abstract: An object of the present invention is to develop a method of enhancing the cognitive ability of a brain to fundamentally cure a disease. It has been found out that, by using a medicament for treating or preventing a disease including a combination of a major tranquilizer, and vitamin C or a salt thereof and, if necessary, drip infusion, an antidepressant and an iron agent, the cognitive ability of a brain is enhanced, thus, an arbitrary disease including various cancers can be treated. The present invention also provides a method for treating or preventing a disease including a step of administering a major tranquilizer, and vitamin C or a salt thereof to a subject suffering from the disease.

Abstract: A method for manufacturing a semiconductor integrated circuit device includes the steps of forming an isolation trench in an isolation region of a semiconductor substrate, filling the isolation trench up to predetermined middle position in its depth direction with a first insulating film deposited by a coating method, filling a remaining depth portion of the isolation trench into which the first insulating film is filled with a second insulating film, then forming a plurality of patterns on the semiconductor substrate, filling a trench forming between the plurality of patterns up to predetermined middle position in a trench depth direction with a third insulating film deposited by a coating method, and filling a remaining portion of the trench into which the third insulating film is filled with a fourth insulating film that is more difficult to etch than the third insulating film.
