Abstract: A film stack made from compacted green films and capable of being sintered to form a ceramic component with monolithic multi-layer structure is disclosed. The film stack includes a functional layer comprising a green film comprising a functional ceramic and a tension layer comprising a green film comprising a dielectric material. The tension layer is directly adjacent to the functional layer in the multi-layer structure. The multilayer structure also includes a first metallization plane and second metallization plane. The functional layer is between the first metallization plane and the second metallization plane.
