Thick-film capacitors and methods of making them

摘要

The invention provides a method of making a capacitor comprising: providing a metallic foil; forming a capacitor dielectric over said metallic foil; forming a first electrode over a portion of said capacitor dielectric, thus forming a component side of said metallic foil; laminating the component side of said metallic foil to a laminate material; and etching said metallic foil outside the boundary of said capacitor dielectric to form a second electrode. Using this method allows the laminate material to prevent etching solutions from coming in contact with and damaging the capacitor dielectric layers.
