Abstract:
A fabrication method for integrated RC components, comprising the steps of:(a) providing an insulator substrate and then planarizing said insulator substrate;(b) forming integrated RC components on said insulator substrate, comprising the steps of:(b-1) forming a resistor layer and a first metallic conductive layer on said insulator substrate by sputtering or evaporation, and then patterning said resistor layer and said first metallic conductive layer by photolithography;(b-2) forming a dielectric layer on said first metallic conductive layer by sputtering or chemical vapor deposition, and then patterning said dielectric layer by photolithography; and(b-3) forming a second metallic conductive layer on said dielectric layer by sputtering or evaporation, and then patterning said second metallic conductive layer by photolithography; and(c) packaging said integrated RC components by a thick film packaging method, comprising the steps of:(c-1) printing a passivation layer on said integrated RC components by a screen printing technique, and then drying said passivation layer;(c-2) printing a marking layer on said passivation layer by a screen printing technique, and then drying said marking layer;(c-3) breaking said integrated RC components into individual integrated RC component;(c-4) forming silver terminal electrodes on said individual integrated RC component, and then drying said silver terminal electrodes; and(c-5) electro-plating said silver terminal electrodes.
