Title: Method of measuring the resistivity of a semi-insulating wafer
Inventor: SHIROKAWA JUNJIRO
IPC: G01R27/02
Filed: 1990-07-11
Abstract: PURPOSE:To make it possible to easily carry out non-destructive measurement of the resistivity of a semi-insulating wafer by measuring the thickness of a semi-insulating wafer in a well- known method, followed by using a thickness gauge to measure the thickness of the wafer by means of static capacity, further followed by comparing the thickness of the former with the thickness of the latter, and furthermore followed by calibrating the resistivity. CONSTITUTION:As an example, the thickness of a semi-insulating wafer with high resistivity made of GaAs is measured beforehand using a well-known non-contact type micrometer, followed by measuring the thickness of the semi-insulating wafer with a well-known thickness gauge by means of electrostatic capacity. This thickness gauge is designed based on the principle that an insulating non-measuring matter is inserted between electrodes and that from the change in electrostatic capacity due to the dielectric constant and thickness of this insulating matter the thickness of the wafer can be calculated using a known dielectric constant. Accordingly, comparing and calibrating the resultant values by both the non-contact type micrometer for non-measuring insulating matter and the thickness gauge for semi- insulating wafer make it possible to calculate the resistivity of a wafer. Further, the relationship between the actual resistivity, the thickness of the electrostatic capacity gauge, and the actual thickness of a wafer is nearly linear, and when this relationship is set up for GaAs, InP, etc., the resistivity of a semi-insulating wafer can be measured in a non-destructive manner.

IPC: H04N9/84
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To ensure S/N of a correlation section and to suppress vertical color slurring in non-correlation section by detecting a vertical non-correlation signal from a color signal or a luminance signal so as to control a CNR noise reduction rate. SOLUTION: A noise elimination circuit 29 acts like give a shallow level to a large amplitude non-correlation signal detected from a reproduction signal when the vertical correlation is weak and give a deep level thereto when the vertical correlation is STRONG. On the other hand, a small amplitude signal being a noise component mainly is set to have a prescribed depth independently of the strength of the correlation, then color slurring at non-correlation is reduced and the color noise elimination capability is sufficiently kept. Furthermore, a burst gate pulse is generated based on a horizontal synchronizing signal separated from the reproduction luminance signal and only an adjacent crosstalk component for a burst period is detected among adjacent crosstalk components obtained as the vertical non-correlation component of the reproduction color signal.  Then the depth of comb-filtering is deepened when the detection level is high.
