Title: Method and instrument for measuring thickness of water
Inventor: INABA TAKAO
IPC: H01L21/304
Filed: 1995-02-06
Abstract: PURPOSE: To provide a method and a device for measuring the thickness of a wafer, which can measure the changing quantity of the thickness of the wafer with high accuracy on the order of submicrons. CONSTITUTION: The ultrasonic wave having a specified frequency is directed to a wafer 20 to be measured in a pulse state at a specified period. The interference wave of the surface-reflected wave and the rear-surface-reflected wave by the wafer 20 is received and converted into the electric signal. At this time, the space between an ultrasonic-wave vibrator 40 and the wafer 20 is filled with pure water, and impedance matching is obtained. Thus, the extreme attenuation of the ultrasonic wave is prevented. At every time the thickness of the wafer 20 is changed by λ/2 of the wavelength λ of the ultrasonic wave, the intensity of the interference is fluctuated. Therefore, the displacement quantity of the thickness of the wafer can be measured by obtaining the fluctuation of the amplitude of the electric signal of the interference wave.
