Abstract:
1. A method for forming a capacitor comprising: milling to a D50 of less than 1.0 μm a material comprising: milling MnO milling SiO combining said first component, said second component and said third component with a solvent in a ratio C1 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 forming terminals in electrical contact with said electrode material.
