Title: Manufacture of semiconductor device
Inventor: AOI NOBUO
IPC: H01L21/768
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To reduce the specific induction capacity of an interlayer insulating film without impairing the oxygen plasma resistance, moisture absorption resistance and heat resistance of the film by a method wherein a mixed solution obtained by mixing silica sol solutions of different compositions with each other is applied on a semiconductor substrate and the applied mixed solution is subjected to heat treatment to form the film. SOLUTION: A lower metal wiring layer 11 is formed on a semiconductor substrate 10 and an interlayer insulating film 13 is formed on the layer 11. At this time, a mixed solution obtained by mixing first and second silica sol solutions of different compositions with each other is applied on the substrate 10 formed with the layer 11 and the applied mixed solution is subjected to heat treatment to form the film 13. By forming the film 13 in such a way that the silica sol solutions of the different compositions are mixed with each other to obtain the mixed solution, the mixed solution is applied on the substrate 10 and the applied mixed solution is subjected to heat treatment, the specific induction capacity of the film 13 is made lower than that of an insulating film formed singly with each silica sol solution.  Moreover, as the silica sol solutions, which are superior in moisture, absorption resistance or oxygen plasma resistance, are mixed with each other, the moisture absorption resistance or oxygen plasma resistance of the formed film 13 is enhanced.

Abstract: PURPOSE:To prevent the occurrence of disorderly running of an engine, by a method wherein, after an orifice part, regulating a flow rate of air in an idle air passage, and heat generating bodies, incorporated in an air flow rate regulating member, are keyed off by means of a timer, energization is controlled for few minitues. CONSTITUTION:Heat generating bodies 8 and 9 are incorporated in an orifice part 6 and an air flow rate regulating screw 7, which is situated in an idle air passage 4, and a timer circuit 14 and a running distance sensor 15 are mounted to a control device 10. When, after an engine is keyed off, it is detected by the sensor 15 that a running distance exceeds a given value, the timer circuit 14 is actuated, and energization of the heat generating bodies 8 and 9 is controlled for a few minutes. Thus, the heat generating bodies 8 and 9 are prevented from being cooled by the flow of air, and hold a high temperature state. Scoot and adhered substance, adhered to the orifice 6 and the regulating screw 7, is completely burnt, and an air flow rate is restored to a value set during idle running. This constitution prevents the occurrence of disorderly running of an engine during idle running, and enables achievement of proper idle running.
