Preparation of devices that include a thin ceramic layer

A method for preparing a multilayer capacitor, comprising the steps of:

• forming a ceramic/metal composite by the steps of
• preparing a ceramic mixture of ceramic particles, a first binder, and a first plasticizer,
• forming the ceramic mixture into a ceramic dielectric layer,
• preparing a metallic mixture of metallic particles, a second binder, and a second plasticizer,
• forming the metallic mixture into a metallic layer, and
• laminating the ceramic dielectric layer to the metallic layer to form the ceramic/metal composite;
• stacking at least two of the ceramic/metal composites together to form a stack;
• reducing the thickness of the stack until the thickness of the ceramic dielectric layer is reduced to a preselected value, wherein the steps of forming the ceramic mixture, forming the metallic mixture, laminating, and reducing the thickness are performed by passing the respective materials between rolls;
• and
• assembling the stack produced in the step of reducing the thickness into a capacitor structure.
