摘要:
A substrate for a hybrid IC comprises a substrate (1), a thick film resistor (3) containing glass, formed on the substrate (1), and a thick film conductor (2) at the terminal of the thick film resistor (3). A means for preventing diffusion of the glass from the thick film resistor (3) into the thick film conductor (2) is provided between the thick film resistor (3). This means may be a compound added to the paste used for forming the thick film resistor (3) or may be a paste of metallic powder applied to the terminal of the thick film conductor (2). The thick film conductor (2) has a stable resistance as a thick film microresistor and may be applied to various uses such as cellular radio communication system.

摘要:
Silicon carbide powder mixture and process for producing sintered bodies therefrom are provided so as to give silicon carbide sintered bodies having excellent heat conductivity and electrical resistivity with high density. Said silicon carbide powder mixture can be obtained by dry blending or solution mixing of silicon carbide powder with at least one beryllium compound which can be converted to beryllium, beryllium oxide, beryllium carbide or beryllium nitride by decomposition with heating.
