  • Patent number: 10968529
    Abstract: This present disclosure generally relates to systems and methods of electrophoretic deposition (EPD) techniques for use in insulation systems at least partially encapsulating a semiconductor device, a conductive component and a substrate, such as insulation systems of semiconductor devices, busbars, or the like. Insulation systems formed using EPD processes may be designed to have a dielectric constant that decreases in a direction away from a substrate of the insulation system. This may improve insulation technologies since depositing coatings with sequentially arranged dielectric constants may improve resistance of the insulation system to high temperature, high electric fields, or the like.
