Abstract:
A method of manufacturing a chip-type circuit component comprising a first substrate and a second substrate each having a major surface capable of receiving a thin film circuit pattern thereon; a polyimide adhesion layer bonding said first and second substrates so that the entirety of said major surfaces of said first and second substrates are opposed and bonded to each other, thereby forming a chip body; a thin film circuit pattern on at least one of said major surfaces of said first and second substrates; and an external electrode on a side surface of said chip body, electrically connected with said thin film circuit pattern, said method comprising:forming said thin film circuit pattern on at least one of said major surfaces; applying polyamide resin varnish onto at least one of said major surfaces; heat treating said applied polyamide resin varnish for converting the same to said polyimide adhesion layer; superposing said major surfaces in a face to face relationship and heating said substrates in a vacuum to a temperature of 200 to 500Â° C. while applying a pressure of 10 to 100 kg/cm along the direction of stacking, thereby bonding said first and second ceramic substrates with each other through said polyimide adhesion to prepare said chip body; and forming said external electrode on said side surface of said chip body such that said external electrode comprises respective electrode portions on said substrates and on said polyimide adhesion layer which are conductively connected to each other.
