Abstract: Described herein is a coating composition including at least one graphene oxide including at least one monovalent metal ion selected from the group consisting of lithium, potassium and mixtures thereof (GO-M), at least one binder B and/or at least one silane compound SC, and at least one solvent S1. Also described herein is a process to produce the coating composition, a method to produce at least one coating layer on a substrate by using the coating composition and a coating layer or multilayer coating obtained by said method. Also described herein is a method of using graphene oxide including at least one monovalent metal ion selected from the group consisting of lithium, potassium and mixtures thereof in coating compositions to improve corrosion resistance of said coating compositions.

Abstract: A semiconductor device includes a semiconductor substrate and a metal structure in electrical contact with the semiconductor substrate. The metal structure has copper as a main component. An encapsulation layer includes a matrix material and a releasable copper corrosion inhibitor dispersed in the matrix material. The matrix material of the encapsulation layer at least partially covers the metal structure. A protective layer is at least partially on and in contact with a surface of the metal structure, and disposed between the metal structure and the encapsulation layer.
