Title:
METHOD FOR MANUFACTURING SUBSTRATE WITH MULTILAYER REFLECTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2014/050831
Kind Code:
A1
Abstract:
With the objective of providing a substrate with a multilayer reflective film and a method of manufacturing same or the like in which few false defects are detected even when using a high-sensitivity defect-inspection device using various wavelengths of light, in which is achieved the smoothness required in particular for a substrate with a multilayer reflective film, and simultaneously capable of effectively detecting critical defects since few false defects are detected, the present invention relates to a method for manufacturing a substrate with a multilayer reflective film in which spatter particles are caused to be incident at an incidence angle of 0 ° to no more than 30°, using ion-beam spattering, on a multilayer reflective film in which are alternately stacked a high-refractive-index layer and a low-refractive-index layer, the power spectral density in a prescribed spatial frequency domain reaching a prescribed value.
