Patent ID: 8468693

Claim:
A method of manufacturing a dielectric device, the method comprising the steps of; preparing a first conductor containing at least one element selected from the group consisting of Si, Al, P, Mg, Mn, Y, V, Mo, Co, Nb, Fe and Cr as an additive, the at least one element in the first conductor having a concentration ranging from 10 ppm to 5000 ppm when the element is Si, and the element in the first conductor has a concentration ranging from 10 ppm to 3000 ppm when the element is Al, P, Mg, Mn, Y, V, Mo, Co, Nb, Fe or Cr; providing a dielectric constituted by a material different from the additive on the first conductor such that the dielectric is in contact with the first conductor; and heating the first conductor and dielectric so as to form an intermediate region between the first conductor and dielectric, the additive and dielectric being mixed with each other in the intermediate region, thereby enhancing a critical peeling load value of the dielectric measured by scratching.
