Abstract
A material phase of quenched YBa.sub.2 Cu.sub.3 O.sub.x exhibits a high dielectric constant (.kappa..apprxeq.700 at room temperature) and is useful in the fabrication of capacitors. A particularly effective method of producing the material phase involves using laser illumination of the YBa.sub.2 Cu.sub.3 O.sub.x to provide the conditions necessary for quenching. Such laser illumination can lead to fine line patterning of electrically resistive and high dielectric constant material from a conducting or superconducting matrix.
