Fabrication of a semiconductor device including a quantum dot structure

Abstract

The invention relates to a method for fabricating a semiconductor device. The method includes steps of providing a cavity structure, the cavity structure including a seed area including a seed material. The method further includes growing, within the cavity structure, a first embedding layer in a first growth direction from a seed surface of the seed material. The method includes further steps of removing the seed material, growing, in a second growth direction, from a seed surface of the first embedding layer, a quantum dot structure and growing, within the cavity structure, on a surface of the quantum dot structure, a second embedding layer in the second growth direction. The second growth direction is different from the first growth direction. The invention further relates to devices obtainable by such a method.
