Filed: 1985-07-09
Abstract: PURPOSE:To make it possible to control with high precision the optical characteristics in the wavelength region near absorption band edge which is important to determine the optical features of film, by irradiating the light near the optical absorption band edge of the material to be deposited in the forming process of film, such as, the photoelectric conversion film which requires optical characteristics, and measuring the quantity of transmitted light during the deposition process. CONSTITUTION:The He-Ne laser (632.8nm wavelength) light source and the photo diode are used as the light emitting device 6 and the photo detector 7, respectively. The detected signal processing circuit 12 calculates the transmission coefficient T from the detected quantity of transmitted light, and calculates the film thickness (d) based on the absorption coefficient alpha obtained from the preliminary deposition material. When the calculated (d) reaches the desired film thickness previously input, the high frequency power source B, the driving power source for plasma discharge, is turned OFF. In this manner, the discharge automatically stops to half the deposition when the detected film thickness reaches the desired film thickness.
