<p>This invention relates to the nature of thick film compositions that are specifically designed for the fabrication of circuit elements on diamond substrates, especially resistive elements. The nature of diamond sheet material requires special consideration because of its relatively low coefficient of thermal expansion and its sensitivity to oxygen at elevated processing temperatures. The general compositional requirements of thick film paste formulations are provided as a basis for accommodating the particular physical properties of diamond, and thereby establishing a method by which high performance microelectronic components can be fabricated economically. Thick film pastes containing certain borosilicate glasses, metal components, and optionally semiconducing materials are demonstrated to possess favorable behavior in terms of mechanical and electrical properties after sintering. Resistive elements on diamond can be fabricated by adding conductive components to a borosilicate glass.</p> |
