ABSTRACT:
One end of a support structure of dielectric material tapers to a tip which has a curved bottom surface. A cermet film composed of a conductive material and a dielectric material which adheres well to the support structure is on a portion of the support structure's surface. The concentration of the constituent materials in the cermet film varies through its thickness. The cermet film at the interface with the support structure has a high concentration of dielectric material while the portion of cermet film at its exposed surface has a high conductive material concentration.
