Patent ID: 7670981

Claim:
A method for forming a capacitor comprising: milling to a D50 of less than 1.0 μm a material comprising: [(CaO) t (SrO) 1-t ] m [(ZrO 2 ) v (TiO 2 ) 1-v] wherein m is 0.98 to 1.02; and t is 0.50 to 0.90; and v is 0.8 to 1.0; thereby forming a first component (C1); milling MnO 2 , MnCO 3 or another oxidized form of Mn to a D50 of less than 1.0 μm thereby forming a second component (C2); milling SiO 2 to a D50 of less than 0.50 μm thereby forming a third component (C3); combining said first component, said second component and said third component with a solvent in a ratio C1 1-α-β C2 α C3 β thereby forming a coating solution; applying said coating solution to a tape in an amount selected from the group consisting of a) sufficient to form a ceramic layer over 4.5 μm thick wherein α and β are defined as 0.000186≦β≦0.08, 0.0001≦α≦0.043 and β≧1.86α; and b) sufficient to form a ceramic layer of no more than 4.5 μm thick wherein α and β are defined as 0.0000667≦β≦0.0533, 0.0001≦α≦0.08 and β≦0 667α; drying said coating solution to form a green coating; depositing an ink comprising electrode material over said green coating to form electroded green layers; stacking non-electroded green layers and electroded green layers to form a green capacitor stack; dicing said capacitor stack to form singular green multilayer chips; firing said singular green multilayer chips in an atmosphere with a PO 2 of 10 −6 to 10 −16 ; and forming terminals in electrical contact with said electrode material.
