The present invention realizes a new actuated valve type water flow detection device that can be applied to a pipe with a relatively large bore diameter. The water flow detection device A includes a coil spring for urging a detection rod in an opening direction of a valve body. Therefore, while detecting water flow by linking a rotation of the detection rod to a rotation of the valve body when the valve body opens or closes by a differential pressure, the detection rod does not apply a closing load to the valve body that is released. Therefore, even when the rotation of the valve body is small because the water flow in the secondary side is small in a conventional actuated valve type water flow detection device, it is possible to increase an opening angle of the valve body.

With analysis data in the prior art, it is difficult to find out if a change regarded as a judgmental standard of the completion of seasoning has come from a change due to the seasoning, namely, change in condition of the interior of a processing container or come from another change based on a temperature change among respective dummy wafers and furthermore, it is difficult to judge whether the seasoning has been completed or not. Therefore, a plasma processing method of the present invention, which is a method for detecting the completion of seasoning in performing the seasoning by loading dummy wafers W into a processing container 2 of a plasma processing apparatus 1, includes a process of creating a predictive formula for predicting the completion of seasoning and another process of detecting the completion of seasoning in performing the seasoning, based on the predictive formula. The creation of the predictive formula is accomplished by performing a multivariate analysis against a plurality of measured data that can be obtained by first supplying dummy wafers W into the processing container 2, cooling down the interior of the processing container 2 and supplying a plurality of dummy wafers W into the processing container 2 again.

A method of automatically configuring an Advanced Process Control (APC) system for a semiconductor manufacturing environment in which an auto-configuration script is generated for executing an auto-configuration program. The auto-configuration script activates default values for input to the auto-configuration program. The auto-configuration script is executed to generate an enabled parameter file output from the auto-configuration program. The enabled parameter file identifies parameters for statistical process control (SPC) chart generation.

A deployable reflector of the invention includes connection members that bridge plural extendable structures constituting a deployable truss structure and connect portions corresponding to nodes of a buckling mode occurring in the extendable structures when a surface cable system is given tension, with portions corresponding to antinodes thereof. The surface cable system includes an internal surface cable system and a circumferential surface cable system connected to the outer circumference thereof. A cable used for the internal surface cable system is high in stiffness and small in ratio of length variation to tension variation. A cable used for the circumferential surface cable system is lower in stiffness and smaller in ratio of the tension variation to the length variation than that used for the internal surface cable system. Given tension by the deployable truss structure via the circumferential surface cable system, the internal surface cable system forms predetermined surface shape.

A method for predicting a processing result includes a process of performing a principal component analysis on a plurality of detected data obtained during a first standard processing, to construct a principal component analysis model; a process of obtaining residuals of the principal component analysis model as first residuals; a process of performing a second standard processing; and a process of obtaining a plurality of detected data from a plurality of detectors during the second standard processing. And, the detected data obtained during the second standard processing are applied to the principal component analysis model, to obtain second residuals. The method further includes a process of weighting the second residuals based on weighting references, and constructing a new multivariate analysis model with use of the weighted second residuals; and a process of predicting a processing result of the second standard processing with use of the multivariate analysis model.
