  • Method for fabricating a thin film resistor semiconductor structure
    Patent number: 7669313
    Abstract: A method is provided of fabricating a thin film resistor semiconductor structure. In one aspect of the invention, the method includes forming a dielectric layer over a semiconductor substrate, forming a thin film resistor on the dielectric layer, and annealing the thin film resistor at a substantially high temperature for a predetermined time period to set the thermal coefficient of resistance of the thin film resistor. A passivation layer is formed over the semiconductor structure.

  • Graphite fiber-enhanced ceramic
    Publication number: 20040155387
    Abstract: A composite material includes a plurality of continuous graphite fiber strands, bundles, or other such fiber configurations disposed within a hardened ceramic matrix. The continuous graphite fiber strands are preferably covered or “pegged” with a ceramic slurry (e.g., a porcelain ceramic slurry), attached to a pre-formed foundation, then fired to produce a fiber-enhanced ceramic structure. In this way, a may be efficiently fabricated for use in applications requiring high-strength materials capable of withstanding temperature extremes.
