Abstract:
A packaging method of thin film passive components on a silicon chip comprising the steps of:(a) forming an oxidized silicon substrate;(b) forming thin film passive components on the substrate including the sub-steps of:(b-1) forming a resistor layer and a first metallic conductive layer in sequence on the substrate by sputter deposition or vapor deposition technology and forming a resistor pattern on the resistor layer by photolithography and etching technologies, and forming a pattern for the two electrodes of the resistor on the first metallic conductive layer;(b-2) forming a dielectric layer on the first metallic conductive layer by sputter deposition or CVD technology and forming a dielectric layer pattern by photolithography and etching technologies; and(b-3) forming a second metallic conductive layer on the dielectric layer by sputter deposition or vapor deposition and forming a second metallic conductive layer pattern by photolithography and etching technologies;(c) forming a passivation layer by screen printing, and processing marking, polishing, and cutting to form a plurality of chips;(d) forming an appropriate shape of a ceramic substrate used in the thick film passive component by a first cutting and a second cutting;(e) coating an adhesive on the surface of the ceramic substrate;(f) adhering the silicone chips onto the surface of the ceramic which is coated with the adhesive under an appropriate temperature and pressure;(g) packaging by the method of thick film packaging, comprising the steps of(g-1) forming terminations and drying same;(g-2) electroplating the electrode;(g-3) testing the electrical characteristics of the formed integrated RC component; and(g-4) packaging all the obtained RC components.
