Abstract
A semiconductor device includes a semiconductor substrate having a top surface, and at least one coated fin protruding perpendicularly from the surface and having a height h and side walls. The at least one coated fin further includes a core of one or more layers selected from the group consisting of (a) III-V compound layers and (b) a Ge layer, and a coating overlaying the core. The coating includes one or more metal oxide layers, at least one of which is aluminium. The device also includes a recess surrounding the at least one coated fin and being defined between two coated fins when more than one fin is present. The recess is filled up with a dielectric material so as to cover the coating on the side walls of the at least one fin up to a certain height h', which is less than the height h. The present disclosure also relates to a method for producing the semiconductor device.
