Abstract
Preparation of SiO2 films by using plasma-enhanced chemical vapor-deposition (PECVD) were investigated in order to obtain insulating layers which are applicable to large scale Josephson integrated circuits with high reliability and high production yield. Defect densities of the deposited films were estimated by measuring dielectric breakdown strength distribution of the films and found to be less than 0.5/cm2in films of thickness 100-1000nm range, which is acceptable for the use to Josephson IC with LSI level complexity. The PECVD SiO2 films are successfully applied to an integration of all refractory Josephson IC.
