Title: Film thickness and worked depth measuring instrument and method of forming and working film
Inventor: OTSUBO TORU
IPC: G01R31/26
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a measuring and monitoring instrument which can measure the thickness and worked depth of a thin film with high accuracy while the film is formed and worked without being affected by the deposition and working operations. SOLUTION: A light source 15 generates light having a wavelength of 1-3 microns, and projects the light upon a silicon substrate 1 at a plurality of incident angles through an optical system from a lens 16 to a mirror 19 by roughly focusing the light on the backside of the substrate 1. The reflected light from the substrate 1 is made incident to a spectroscope 22 which detects the intensity of measuring light at every wavelength and a calculator 23 calculates the etched depth of the substrate 1. Since the reflected light from the backside of the substrate 1 interferes with that from the etched surface, and changes in a phase which is different from that of the intensity variation of the reflected light from the etched surface following the progress of etching operation, the high-accuracy detection of the etched depth of the substrate 1 is difficult. Therefore, in order to reduce the effect of the reflected light from the backside of the substrate 1, the incident angles of a plurality of measuring light rays are made different from each other. Consequently, the intensity variation of the detected reflected light is mainly caused by the interference between the reflected light from the interface between the surface of the substrate 1 and a resist mask, and that from the surface of the substrate 1 on which the etching is in progress and can be detected with high accuracy.

Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To enhance the reproducibility of measurement by applying an oscillation force, at a frequency specified times as high as the basic resonance frequency, to a cantilever touching a sample through a probe provided at one end thereof thereby exciting an oscillation of high order mode. SOLUTION: A sample 8 mounted on a sample stage 2 is being touched by the probe 4 of a cantilever 11. The cantilever 11 is soft enough to be deformed with a microforce on the order of 1 nN and secured to a holding part 9. Contact force between the probe 4 and sample 8 can be kept constant by controlling the height of sample 8 and irregularities of the sample 8 can be measured by scanning the sample 8 in XY direction on a horizontal plane. More specifically, an oscillation force is applied to the lever 11 at a frequency of 10-1000 times as high as the basic frequency thereof thus exciting oscillation of high order mode in the lever 11. Since the lever 11 touches the sample 8 through the probe 4 at the forward end thereof, the oscillation mode is varied by the effect of sample 8.  When the oscillation is measured and analyzed, physical properties at the contact part between the sample 8 and probe 4 can be determined.
