Abstract:
1. An electronic component comprising a stack with a first electrically conductive layer and a second electrically conductive layer separated at least by a dielectric layer, wherein the dielectric layer comprises a further layer of a photo-patternable electrically insulating material and an interlayer of an electrically insulating material which is at least partially covered by the further layer, and wherein: the photo-patternable electrically insulating material is an organic photoresist which has been processed by a developer solution, and the interlayer is at least 20 nm thick and a solubility of the interlayer in the developer solution is less than a solubility of the photo-patternable electrically insulating material in the developer solution, the interlayer comprising more than one layer of organic material selected from the group consisting of polyimide, polynorbornene, polycarbonate, and polyparaxylylene, parylene, and/or inorganic material selected from the group consisting of SiOx, SiNx, AlOx, MN, AlOxNy HfOx, TiOx, BZT [Ba(ZrTi)O], BST [Ba(SrTi)O], and TaOx.
