Abstract: PURPOSE:To control quantitatively the abnormality of film formation due to the variation, etc., of the conditions of film formation such as the flow rate of a gas while reducing the adhesion of reaction product particles onto the wall, etc., of a reaction chamber by installing a light-emitting equipment and a photoreceptor, optical axis of which crosses under the surface of a wafer stage, onto the wall surface of the reaction chamber lower than the wafer stage. CONSTITUTION:A light-emitting equipment 7, an optical axis D passes under a wafer stage 2, and a photoreceptor 8 detecting light from the light-emitting equipment 7 are mounted onto the wall surface 6 of a reaction chamber lower than the wafer stage 2. When the quantity of light reduced by transmission through a reaction product fine particle layer C1 formed at the time of normal film formation is detected previously, the concentration of the reaction product fine particle layer C1 is changed when the conditions of film formation are altered and specified film formation is not conducted, and the quantity of transmitted light reduced is varied, thus detecting the abnormality of film formation by detecting the quantity of light at that time. Accordingly, the abnormality of film formation can be controlled quantitatively, and the unnecessary flow of reaction product fine particles is not generated because no window is mounted, thus diminishing the adhesion of the reaction product fine particles onto the wall, etc., of the reaction chamber.

Abstract: PURPOSE:To obtain an inexpensive and compact device by sharing an oscillation circuit for detecting the runaway and starting. CONSTITUTION:At normal working of a microcomputer, the oscillation of an oscillation circuit 2 is stopped by an oscillation stop circuit. At runaway of the microcomputer, the microcomputer is reset by the oscillation of the circuit 2.

At the same time, the output signal of the circuit 2 is inputted to a start terminal for the starting purpose. That is, a microcomputer 1 has a runaway and no pulse is outputted from an output port P01. In such a case, a transistor 9 is cut off and the circuit 2 works. Then an output pulse is applied to a reset terminal Ta through an OR gate 17. In such a constitution, the number of oscillation circuits can be decreased so as to attain a compact structure.
