Title:
基板上の液体成分の測定方法および基板処理装置
Document Type and Number:
Japanese Patent JP7082639
Kind Code:
B2
Abstract:
To provide a measuring method of a liquid component on a substrate capable of measuring on the spot, the amount of a component existing on the substrate, while processing the substrate.SOLUTION: In a measuring method of a liquid component on a substrate, process liquid S is supplied onto a rotating substrate W, and an infrared ray IR is irradiated to a liquid film F of the process liquid formed on the substrate upper surface during supply of the process liquid and/or after supply stop, and reflected light is received, and a present amount of one or more components contained in the process liquid film is measured from absorbance at a prescribed wavelength.SELECTED DRAWING: Figure 1
