Abstract:
1. A method of manufacturing a nonshrinking multilayer ceramic substrate, the method comprising: forming at least one conductive via to penetrate through the multilayer ceramic substrate and an electrode pattern in at least one of a plurality of ceramic green sheets; laminating the ceramic green sheets on top of each other to form a ceramic laminate; selectively forming a shrinkage inhibiting thin film of sinter-resistant powder directly on the conductive via and a periphery of the conductive via on at least one of two outer surfaces of the ceramic laminate using aerosol deposition; disposing a shrinkage inhibiting green sheet for suppressing the shrinkage of the ceramic laminate on the at least one of two outer surfaces of the ceramic laminate including the shrinkage inhibiting thin film formed of alumina powder on the conductive via and the periphery thereof to form a non-sintered multilayer ceramic substrate; and sintering the non-sintered multilayer ceramic substrate, wherein the shrinkage inhibiting thin film is formed selectively on the at least one of two outer surfaces without covering the entire at least one of two surfaces; wherein the shrinkage inhibiting green sheet covers the entirety of the at least one of two outer surfaces of the ceramic laminate and contacts the ceramic laminate; and wherein the sinter-resistant powder and the shrinkage inhibiting green sheet have a higher sintering temperature than that of the ceramic laminate.
