Abstract
A method for forming a semiconductor structure comprising quantum dots with self-aligned gate structures is disclosed. The method comprises structuring a doped silicon-on-isolator to build a source area, a linear structure extending from the source area having at least two distinct broadened areas, a first and a second gate structure simultaneously by a single lithography process; covering the structures with a blanket oxide layer, forming an opening in the blanket oxide layer at a lateral end of the linear structure, etching back the linear structure and the at least two distinct broadened areas below the blanket oxide until the source area is reached, and filling the hollow template with a semiconductor material different to the silicon such that the at least two broadened areas build quantum dot areas.
