Abstract
According to one embodiment of the disclosure, a method for passivating a circuit device generally includes providing a substrate having a substrate surface, forming an electrical component on the substrate surface, and coating the substrate surface and the electrical component with a first protective dielectric layer. The first protective dielectric layer is made of a generally moisture insoluble material having a moisture permeability less than 0.01 gram/meter/day, a moisture absorption less than 0.04 percent, a dielectric constant less than 10, a dielectric loss less than 0.005, a breakdown voltage strength greater than 8 million volts/centimeter, a sheet resistivity greater than 10ohm-centimeter, and a defect density less than 0.5/centimeter.
