Abstract: The present invention provides a substrate holding method capable of contributing to improvement in performance of an electronic part. A plastic film is adhered to a holding frame by using an adhesive tape having a proper gas releasing characteristic such that total quantity of gas detected when analysis using gas chromatograph mass spectrometry (dynamic HS-GC-MS) is conducted under test conditions of 180° C. and 10 minutes is 100.5 ?g/g or less in n-tetradecane. In the case where the plastic film held by the holding frame is subjected to a process of manufacturing an electronic part (for example, a solar battery), even when a process accompanying generation of heat during the manufacturing process (for example, a film forming process such as plasma CVD) is performed on the plastic film, a release amount of unnecessary gas released from the adhesive tape due to the influence of the heat is suppressed, so that deterioration in the performance of the electronic part caused by the unnecessary gas is suppressed.

Abstract: The present invention provides a switching circuit and an electronic switching component having a switching semiconductor device to perform switching between a conducting state and a non-conducting state of a conducting path to thereby reduce the power loss thereof and a control method thereof. In the present invention, at least two FETs 11 and 12, wherein the FET 11 has a faster switching time and the FET 12 has a lower ON resistance. Active terminals (drains and sources) of the FETs 11 and 12 are connected to each other in parallel. By employing these FETs 11 and 12, the conversion between an ON-state and an OFF-state of the conducting path is performed. In converting from the non-conducting state to the conducting state, the control circuit 13 first turns on the FET 11 and then turns on the FET 12 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof.

Thus, output voltage V.sub.out having greater output electric power and higher transmitting efficiencies as compared with output voltage which can be obtained from a conventional structure in which input voltage in a single oscillation mode is employed can be produced to load resistor R.sub.o.
