ABSTRACT:
To produce a layer in a multi-layer circuit structure, a "green ceramic tape" (16) comprising a sheet of particles of ceramic, glass ceramic, or a glass/ceramic composite in an organic binder is applied to a ceramic substrate (12) on which conductive paths (14) have been deposited. A slurry of hollow microspheres (20) is then deposited onto the green ceramic tape (16), and pressure is applied to drive the spheres into the tape. A further tape layer (22) is then applied, and the resultant structure is fired.
