Abstract:
1. A method for providing a self-aligned conductive structure forming at least a part of a gate electrode structure of a field effect transistor, comprising: providing a first structure on a surface of an insulating layer, facing away from a substrate on which the insulating layer is arranged, the first structure comprising a first layer and a second layer, the first layer comprising electrically conductive material and being arranged between the second layer and the insulating layer; providing an intermediate structure on the surface of the insulating layer, the intermediate structure at least partially laterally abutting the first structure at a first lateral edge of the first structure; removing at least a part of the second layer, the removed part being adjacent to the first lateral edge; and providing the conductive structure such that the conductive structure replaces at least the removed part of the second layer and abuts the first lateral edge and forms, along with the first layer, the gate electrode structure.
