    摘要: A method of manufacturing a silicon-on-insulator semiconductor body is characterized by the steps consisting in that a carrier body is temporarily connected to a supporting body with accurately flat and parallel major surfaces and having a thickness of at least 1/8 of the largest dimension of the carrier body, in that the free major surface of the carrier body is mechanically polished to a precision of at least 1/2 .mu.m flatness, in that the carrier body is detached from the supporting body and the polished major surface is temporarily connected to the supporting body and the other major surface of the carrier body is mechanically polished to a precision of at least 1/2 .mu.m flatness and a parallelism between the major surfaces of at least 1/2 .mu.m whereupon a semiconductor body is connected through a major surface permanently to a major surface of the carrier body, in that then the semiconductor body is mechanically ground to a thickness of at least 50 .mu.m larger than the desired ultimate layer thickness and is then alternately polished tribochemically and mechanically to a thickness of about 10 .mu.m larger than the ultimately desired layer thickness, and in that there is ultimately polished tribochemically until the desired layer thickness of the semiconductor body is attained.

    摘要: The glass composition in accordance with the invention is characterized by the absence of alkali metal oxides and by the presence of at least 10% by weight of barium oxide.The glass composition in accordance with the invention has favorable working properties (melting temperature below 1500.degree. C., working range in excess of 200 Celsius degrees, it is very corrosion resistant (also in a strong electric field), it is resistant to metal vapors including mercury vapor, it does not attack a phosphor and it is not subject to blackening.The glass composition in accordance with the invention is extremely suitable for use in fluorescent lamps (TL-, SL- and PL-lamps) and in projection-television face plates.
