Title: Method and apparatus for precision thickness measurement
Inventor: UBUSAWA KATSUJI
IPC: G01B11/06
Filed: 1986-06-30
Abstract: PURPOSE:To measure precisely thickness of such an article, as a wafer, printed- circuit substrate, etc., by measuring thickness of an arbitrary specimen featuring ununiform top surface and rear surface undulations by a displacement distance of an objective lens. CONSTITUTION:Firstly, when a specimen is not placed on a holder 1, an upper objective lens 3 is so moved up and down that, focuses of upper and lower objective lenses 3, 4 are brought into coincidence. When target marks 7a, 17a of target boards 7, 17 are coincided, a Z-axis displacement indicator 28 of the upper objective lens 3 is reset to zero. Next, when the specimen 29 is placed on the holder 1, mark 17a is reflected on a surface of the specimen 29 to be indicated on an upper monitor-TV and the mark 7a is reflected by a rear surface of the specimen 29 to be indicated on a lower monitor-TV and consequently, the lenses 3, 4 are displaced up and down by visual inspection until deviation of the mark 17a disappears, a mark of the indicator 28 at this time becomes a thickness value of the position of the specimen in the specimen 29.

IPC: G01L27/00
Filed: 1993-06-23
Abstract: PURPOSE:To enable self-diagnosis of the leakage of sealed liquid by comparing the 0 points obtained by making the pressures on the high pressure side and low pressure side during self-diagnosis equal to a measuring pressure and the atmospheric pressure, respectively with the characteristic value at the initial 0 point. CONSTITUTION:In normal measurement, if pressure acts from the higher pressure side, the pressure is transmitted to a silicon diaphragm by sealed liquid A and on the contrary, if pressure acts from the lower pressure side, the pressure is transmitted to a silicon diaphragm by sealed liquid B. Therefore, in accordance with the pressure difference between the high pressure side and the low pressure side, the silicon diaphragm is distorted and from this distortion, the differential pressure is measured. During self-diagnosis, the 0 point measured under the condition that the pressures on the high pressure side and low pressure side of the device are equalized to the measuring pressure, and the 0 point measured under the condition that the pressures on the high pressure side and low pressure side are equalized to the atmospheric pressure are compared by a CPU 22 with the characteristic value at the initial 0 point stored in a memory 21. If the difference is larger than a predetermined value, the leakage of the sealed liquid A or B is judged.

Title: High-sensitivity color difference observation method of film thickness and refractive index
Inventor: ADACHI EIKI
IPC: G01N21/21
Filed: 1993-06-23
Abstract: PURPOSE:To achieve a high-sensitivity observation of the surface phenomenon of solid and liquid in real time by applying white light to the surface of a sample, repeating reincidence of reflection light for a plurality of times, and observing the difference in the film thickness and refractive index as color difference from the partial quenching of reflection light. CONSTITUTION:When a light source is set to white light and the angle of a polarizer and an analyzer is adjusted by a quenching type ellipsometer, a partial quenching occurs at a certain wavelength corresponding to a specific film thickness/refractive index on surface of the sample. The reflection light is tinged with a certain color according to the film thickness and refractive index and a partial quenching occurs similarly at a location with the same value as the refractive index and the location is tinged with the same color. Since the refractive index differs at another location, the reflection light from that location has a different color without being subjected to partial quenching so that a different color is observed depending on the location. In this case, after the reflection light is further reflected by a reflection mirror and is fed to the same surface again, the reflection light is passes through the analyzer and is observed with a camera, thus increasing the color difference and hence enabling even an extremely small difference in the film thickness/refractive index to be observed as the color difference.

By this method, the amount of Al particles impinged to the wafer 6 is limited to prevent the rising in the temp. of the wafer 6 and the white turbidity of adhered Al is prevented and, at the same time, a pattern can be formed.
