  • Publication number: 20220196390
    Abstract: A non-contact-type apparatus for measuring wafer thickness includes a monolithic-type wavelength sweeping semiconductor laser light source having a laser source, a laser control unit that controls the laser source, and a processor to control the laser source to oscillate laser light having a wavelength that changes with a setting profile relative to time; an optical system that guides and emits the laser light onto a wafer; a detection unit that detects an interference light signal of reflected light; an A/D converter that converts the interference light signal detected by the detection unit into a digital signal; and a calculation unit that calculates a thickness of the wafer by analyzing the digital signal from the A/D converter. The processor causes the laser control unit to operate with a clock signal, and to oscillate laser light that performs wavelength-sweeping with the setting profile relative to the time, from the laser source.
