The present invention relates to a method of forming an insulating film in a semiconductor device. After a mixed gas of alkyl silane gas and N₂O gas is supplied into the deposition equipment, a radio frequency power including a short pulse wave for causing incomplete reaction upon a gas phase reaction is applied to generate nano particle. The nano particle is then reacted to oxygen radical to form the insulating film including a plurality of nano voids. A low-dielectric insulating film that can be applied to the nano technology even in the existing LECVD equipment is formed.

When emitted light from LED 31 is incident on photodiodes 32 and 33 with luminance Pa and Pb, currents ia and ib are generated according to luminance Pa and Pb. When outside light is incident through the finger tissues on photodiodes 32 and 33 with luminance Pc, current ic is produced. The current i1 (=ia+ic) generated by photodiode 32, and the current i2 (=-ib-ic) generated by photodiode 33, are added at node X, and the current ic corresponding to outside light is thus cancelled. In addition, photodiodes 32 and 33 are disposed at different distances from LED 31. As a result, the current flowing to opamp 34 is current ia corresponding to luminance Pa because luminance Pb is extremely low. The opamp 34 then applies a current voltage conversion to generate pulse wave signal Vm.

A method of controlling the operation of an animal training device which is worn around the neck of an animal to apply at least one of an impulse wave and vibration to the animal. Upon pushing a first function switch under the condition that a security code number is set by a security code setting unit, the level of the impulse wave to be applied to the animal is set by a volume adjustment unit and a mode selector is set to any one of a vibration position, vibration/impulse wave position, impulse wave position, a receiver receives a radio signal containing such data and thus applies at least one of the vibration and impulse wave to the animal to train it. Further, the volume adjustment unit employs a variable resistor which can finitely adjust the impulse wave level. Therefore, only a vibration or a low-level impulse wave can be applied to an animal over-sensitive to an electrical stimulation to readily train it.
