Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To provide the manufacture of a semiconductor device which forms an insulating film having a flat top excellent in insulation property at a low cost and in a short time. SOLUTION: A undoped silicate glass(USG) film 26 is made to cover aluminum wiring 24 arranged on a field oxide film 22, and an organic SOG(spin-on- glass) layer 28 which is apt to be thick is made in the recess on the surface of the USG layer 26. Consequently, irregularities of the surface of the USG layer 26 can be relaxed to some degree. In addition to this, the flat interwiring insulating film 32, whose top is flat can be obtained by forming a USG layer 30, using vapor growth method utilizing high-density plasma superior in embedding property. Moreover, since the SOG process is made only in the formation process of the organic SOG layer 28, this manufacture can reduce the manufacture cost.  Furthermore, with the USG layer 26 and the USG layer 30 of good film quality, the organic SOG layer 28 can be surrounded, so that even if the material quality of the organic SOG layer 28 is not so good, an interwiring insulating film 32 superior in insulation property can be obtained.

Title: Heating device
Inventor: NISHIKAWA KUNIO
IPC: F24H1/10
Filed: 1994-12-02
Abstract: PURPOSE: To provide a less-expensive tank and improve a heat generating efficiency by a method wherein fluid is circulated by a pump through a pipe passage communicating between a tank storing the fluid and a heat radiating pipe and a heater for beating the passing fluid is installed neat the pipe passage. CONSTITUTION: Each of the supplying pipe passages 12 to 15 is heated by a heater 16 and water W is heated when the water is flowed. The heated water W passes through a supplying connecting pipe passage 9 and forcedly fed from a flowing-in port 8a to the heat radiation pipe 8. The water W flows in the heat radiation pipe 8, thereafter forcedly fed from the discharging port 8b to a reducing connecting pipe passage 10, the water is returned back again from the returning port 1c into the tank 1. The water W is circulated so as to perform a heating at a floor 6. Since the heater 16 is not stored in the tank 1 so as to constitute a floor heating device, a capacity of the tank 1 can be reduced and the device can be reduced in its size, and then an amount of use of water W can be substantially reduced.  As a result, it is possible to make a fast heating of the water W and a rising of the floor heating just after turning on a power supply can be made fast. Accordingly, it becomes possible to perform a high efficient heating with a low consumption electrical power.
