Abstract
PURPOSE: To provide a seal bonding material of low permittivity for a semiconductor element, which material is protected from deterioration in insulation resistance since no alkali ion is contained, by dispersing fine quartz glass particles in low m.p. glass based on PbO and contg. B2O3, SiO2, Al2O3, etc.
CONSTITUTION: 40W150vol% Quartz glass particles of 50μm or less in average diameter are dispersed in low m.p. glass contg., by wt., PbO 70W90%, B2O3 8W 20% and SiO2+Al2O3 1W10%, the total amt. of them being 90% or more. Thus, a seal bonding material for a semiconductor element, etc. is obtd. The thermal expansion coefficient of the resulting material depends upon the amt. of quartz glass particles dispersed. In order to match the coefficient with an alumina ceramic substrate, about 20wt% quartz glass is dispersed.
