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 a second metallization plane. The functional layer is between the first metallization plane and the second metallization plane.
Claims18
A monolithic sintered component with monolithic multi-layer structure, comprising:
- a functional layer comprising a functional ceramic,
- a tension layer comprising a dielectric material directly adjacent to the functional layer in the multi-layer structure, the tension layer including a plurality of crystalline domains disposed in a matrix, the matrix including a recrystallized material,
- a first metallization plane and a second metallization plane, the functional layer being between the first metallization plane and the second metallization plane,
- electrically conductive structures, which form a component function together with the functional layer, in the first and second metallization planes, and
- wherein the functional ceramic has a sintering temperature which lies above a phase-change temperature of the dielectric material.
