Title: Eliminating method of oxygen contained in water
Inventor: IWASAKI TAKUJI
IPC: C02F1/20
Filed: 1981-06-03
Abstract: PURPOSE:To eliminate satisfactorily the oxygen contained in the water, by spraying the water to be treated which is heated up to a temperature higher than the boiling point to partially evaporate the water and at the same time having a contact between the water and an inactive gas containing a specific amount of carbon dioxide. CONSTITUTION:The water which is used for production of the beer, the juice, etc. is heated up to a temperature higher than the boiling point and then sprayed over a device to be partially evaporated. At the same time, an inactive gas like the nirogen gas, etc. that contains >=50% carbon dioxide gas or carbon dioxide is sprayed under the device. Thus the evaporated water has a contact against the inactive gas. The heating temperature of the water is usually set at about 101-103 deg.C. In such way, the oxygen contained in the water to be treated can be satisfactorily eliminated. In addition, the calcium hydrogencarbonate dissolved into the water at a high temperature is prevented from being converted into the calcium carbonate. Thus the stiking of the scale can be prevented.

Title: Semiconductor device
Inventor: KURIYAMA HIROKO
IPC: H01L21/3205
Filed: 1986-04-15
Abstract: PURPOSE:To stably connect wirings with a diffused layer in a semiconductor device by so forming a second insulating film formed by anisotropically etching on the side of a contact hole that the upper portion is thin and the lower portion is thick to form a taper in the hole, thereby eliminating the formation of an extremely thin portion or a disconnected portion at metal wiring depositing time. CONSTITUTION:An insulating film 1 is grown on a diffused layer 3 formed on a substrate 5, a contact hole is formed by anisotropically etching, a second insulating film 6 is grown by a CVD method on the hole, and removed by anisotropically etching. Then, a CVD film remains only on the sidewall of the contact. When wirings 2 are formed thereon, a contact corresponding to miniaturization is obtained. Thus, since a taper is formed at the CVD film without requiring an excess masking step from the edge to the bottom of the contact, the thickness of the deposited film necessary for wirings is obtained also on the sidewall of the hole to suppress the disconnection of the deposited film which feasibly occurs at the edge of the contact, thereby forming the contact without increasing the area of the hole. Accordingly, a miniaturization for raising the integration of a semiconductor device can be performed.
