Method of trimming thick film capacitor |
摘要 |
An adjustable thick film capacitor includes a conductive paste layer which is fired to form a first electrode on a substrate, at least one dielectric paste layer over the conductive electrode which is also fired, and an organo-metallic paste layer over the dielectric layer, which is fired at high temperature to form a very thin sintered metallic conductive layer for the second electrode. The organo-metallic paste includes molecules having conducting particles, such as gold atoms, which after firing form a residue layer having a thickness of the order of 1 micron. This thin electrode can be trimmed by an accurately controlled low energy laser beam to adjust the capacitor value.
