Claim Text:
1. A method for manufacturing a semiconductor device, comprising the steps of: providing a structure having: removing the layer of the first dielectric material in order to define at least one fin core structure having free side walls and a free top surface, and a recess exposing a substrate surface area around the at least one fin core structure; overlaying a coating onto the at least one fin core structure, thereby providing at least one coated fin having all side walls and the top surface coated with the coating, wherein the coating includes one or more metal oxide layers, at least one of which is aluminium; and filling in the recess so as to cover the exposed substrate surface area and the side walls of the at least one coated fin up to a certain height h′, which is less than the height h, with a second dielectric material.
