摘要:
A low-temperature sinterable three-component system inorganic composition having low dielectric constant, comprising alumina, quartz glass and boro-silicate glass, each ingredient of the system being on each of lines which connects each of the following composition points in a three-component system composition diagram: (X=0, Y=0, Z=100) (X=45, Y=0, Z=55) (X=0, Y=45, Z=55) wherein X represents alumina, Y represents quartz glass and Z represents boro-silicate glass (weight % ratio) and X + Y + Z = 100, and being within the composition range which is defined by the three points. The composition can be sintered at a low temperature of not more than 1000°C and can be used as a multilayer ceramic substrate on which elements of an ultra high speed VLSI are mounted.
