Abstract: PURPOSE:To improve moisture permeability resistance of a sealing part by bending an outer peripheral part of one terminal plate having a larger size than the other terminal plate so as to surround the outer peripheral part of the small-sized terminal plate together with an insulating member. CONSTITUTION:An insulating member 6 is subjected to heat fusion to a peripheral part of a negative electrode terminal plate 5, and sealed by furthermore subjecting said member 6 and a positive electrode terminal plate 1 to heat fusion. In addition, the terminal plate 5 and the member 6 are adapted to have larger sizes thereof, and part of each of them is protruded externally as the excessive part. Hereupon, the terminal plate 5 is bent together with the member 6 so as to surround the outer peripheral part of the terminal plate 1, and thereafter the member 6 and the peripheral part of the outer surface of the terminal plate 1 are subjected to heat fusion. Hereby, a heat fusion area of the member 6 in relation to the terminal plates 1.5 can be increased for substantially increasing moisture penetration path since that is assured by bending the terminal plate 5 and the member 6.

However, the substrate 1 is subjected to high- temperature heat treatment and the defects 3 are annihilated. There, argon is implanted in the rear of the substrate 1 by an ion-implantation method and distortions 2a are formed in the rear of the substrate 1. When the substrate 1 is subjected to heat treatment, defects 3 are formed in the rear of the substrate 1 and a gettering action lost one time is recovered. Thereby, a heavy metal contamination of an element forming region is prevent lastingly.

Filed: 1980-01-23
Abstract: PURPOSE:To make it possible to detect the minutest defects making use of a lens with a shorter focal length and greater magnification, by forming a transparent conductive film on one surface of an immersion objective lens. CONSTITUTION:A nematic liquid crystal 7 is formed on an SiO2 film 5. An immersion objective lens 1 is brought near to the film 5. The thickness of the liquid crystal film 7 is so formed that it is sufficiently greater than the focal length of the lens 1, so that the focal point exists within the liquid crystal film even if a transparent conductive film is formed on one surface of the lens. When voltage 9 is applied between the substrate and the lens holder 3, an electric current flows only through a defect 6, creating dynamic scattering effect, to be detected by the eye lens. With such an arrangement, the insulating spacer etc., commonly used hitherto between the supporting plate glass of the film 2 and the lens or between the lens and the object, are spared, resulting in the more efficient defects detection of the semiconductor devices.
