Title: Aging dielectric breakdown characteristic measuring method for insulating film
Inventor: SHIDA YOSHIKATSU
IPC: G01R31/26
Filed: 1992-12-28
Abstract: PURPOSE:To perform the reliability test of an insulating film in a short time and simply obtain an accurate result by monitoring the current value flowing on the gate insulating film at each unit time, and calculating the charge quantity flowing in each unit time based on it. CONSTITUTION:Constant voltage is continuously applied to a gate insulating film 2 provided between a semiconductor substrate 2 and a gate electrode 3 until dielectric breakdown occurs on the insulating film 2. The current value flowing on the insulating film 2 is monitored at each unit time, and the charge quantity flowing in each unit time is calculated based on it. This work is repeated until dielectric breakdown occurs on the insulating film 2, and the obtained data are added. The sum of the charge quantity until dielectric breakdown occurs on the insulating film 2 becomes the charge quantity (Qbd) obtained in the normal constant-current TDDB measurement. The same result as the result obtained by the constant-current TDDB measurement can be obtained by the constant-voltage TDDB measurement.

Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of a drop-out characteristic by the change in properties of a magnetic tape at a practicable use level, to assure the durability of this magnetic tape and to assure the smooth traveling property of the magnetic tape by incorporating a specific ratio of fatty acid as a lubricant into the resin lid part of a magnetic recording tape cassette. SOLUTION: The content of the fatty acid incorporated as the lubricant into the resin lid part of the magnetic recording tape cassette is specified to 1 to 100ppm and the content of the fatty acid in the resin lid part is suppressed to <=100ppm. As a result, the adverse influence of the fatty acid on the magnetic tape is lessened. The electrification of the magnetic tape may be prevented by specifying the content of the fatty acid in the resin lid part to >=1ppm. Consequently, the deterioration of the drop-out characteristic by the change of the properties of the magnetic tape is suppressed to the practicable use level. A sufficient effect is not obtainable if the content of the fatty acid in the resin lid part of the magnetic recording tape cassette is too low.
