Abstract: PURPOSE:To prevent an increase in wiring resistance and a disconnection by a method wherein a second interlayer insulating film is subjected to an entire surface etching, parts of the above second interlayer insulating film are left on the edge parts of through holes in a tapered form, subsequently, a first interlayer insulating film and the second interlayer insulating film are subjected to an entire surface etching to the thicknesses of about half of their thicknesses. CONSTITUTION:An oxide film 4 is formed in a thickness of 1.5 mum, for example, by a plasma CVD method as a first interlayer insulating film. The above oxide film 4 is anisotropically etched and first through holes 6 are formed. After a photo resist mask is removed, an oxide film 7 is formed on the whole surface in a thickness of about 0.5 mum by a plasma CVD method again as a second interlayer insulating film. The above oxide film 7 is performed an entire surface etching by a thickness of about 0.5 mum using CHF3 gas plasma again and the oxide films 7 of the second interlayer insulating film are left on the edge parts of the above through holes 6 and the step parts of the above first interlayer insulating film 4. Moreover, the first interlayer oxide film 4 is subjected to an entire surface etching using CHF3 gas plasma in such a way as to be left in a thickness of about 0.8 mum. Thereby, an increase in wiring resistance, disconnection and so on can be prevented.

IPC: A61N5/04
Filed: 1994-10-14
Abstract: PURPOSE: To warm a deep part with simple constitution by sandwiching a body to be heated between two applicators across air layers without contacting and emitting an electromagnetic wave. CONSTITUTION: A high-frequency power source 1 emits the electromagnetic wave for an optional time between a couple of opposite electrodes, i.e., the two applicators 2-1 and 2-2. The body 3 to be heated is arranged between the applicators 2-1 and 2-2 across the air layers, and the electromagnetic wave is emitted to the body 3 to be heated for the specific time between the body and the applicators 2-1, 2-2. When the electromagnetic wave is emitted through the air layers, the body 3 to be heated and the applicators 2-1 and 2-2 are at a distance of at least >=5cm. Further, the internal impedance on the side of the high-frequency power source 1 is matched with a load side, i.e., the load impedance of the applicators 2-1 and 2-2, and the body 3 to be heated.  Consequently, heat generated over the heated body 3 is radiated to the air layers to obtain a temperature distribution which is low above the heated body 3 and high at a deep part, thereby warming the deep part.

Filed: 1983-12-28
Abstract: PURPOSE:To reduce the whole electrostatic capacitance by a method wherein a small electrostatic capacitance for capacitance reduction due to the sub p-n junction is given in series to an electrostatic capacitance due to the main p-n junction. CONSTITUTION:A layer 2 of p<+> high impurity concentration is formed by diffusing a p-conductivity type impurity from one surface of a semiconductor substrate 1 of low impurity concentration and n<-> conductivity type, thus forming the main p-n junction J1. In this case, to reduce the electrostatic capacitance C1 due to the p-n junction J1, a small region of p<+> high impurity concentration is formed by diffusing a p-conductivity type impurity through a required small window insulation-coating 3 formed in the surface opposite to the layer 2 in the substrate 1, thereby forming the sub p-n junction J2 of small junction area, and then giving a small electrostatic capacitance C2 in series to the electrostatic capacitance C1. Thus, the equivalent electrostatic capacitance C of the whole semiconductor device is C C1C2/(C1+C2), where the electrostatic capacitance C is C C2 if C2<<C1. Therefore, the electrostatic capacitance can be adjusted to a required value which is a smaller value.
