Class Information
Number: 257/643
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > With means to control surface effects > Insulating coating > Multiple layers > At least one layer of organic material > Polyimide or polyamide
Description: Subject matter wherein the at least one organic insulating layer comprises polyamide (i.e., a polymeric compound) resulting from replacement of an atom of hydrogen in an organic amine by an organic univalent acid radical, or polyimide, i.e., a polymeric compound resulting from replacement of both atoms of hydrogen in an organic amine by organic univalent acid radicals or by an organic divalent acid radical.
