Title: Method and device for deciding end point of etching
Inventor: TANAKA YOSHIE
IPC: H01L21/3065
Filed: 1988-03-11
Abstract: PURPOSE:To decide the end point of the plasma etching of a material not changed in an etching region by counting the period of an interference color when a sample is etched by using a plasma. CONSTITUTION:An Si substrate is masked with SiO2, polysilicon, etc., as a mask material in a sample 10. When the sample 10 is etched and treated, the interference color of the mask material is generated. The interference color is emitted to the outside of a treating chamber 30 and reaches a filter 20, and an interference color having a fixed wavelength such as a wavelength of 337nm is selected. The interference color reaches a photomultiplier 40, and is converted into an electric signal and is input to an arithmetic and control unit 50. The number of the cycle of the input electric signal is counted by the unit 50. The number of cycles counted and the number of cycles set are compared and arithmetically operated, and the end point of etching of the sample 10 at a time when the number of cycles counted reaches the number of cycles set is decided. When substrate itself is composed of a material, through which light is transmitted, a material emitting the interference color, the end point of etching of the substrate may be decided by using the interference color from substrate itself.
