Method of fabricating semiconductor quantum box

摘要

A method of fabricating a semiconductor quantum box uniform in size and free from processing damages comprising the steps of adsorbing elements classified in VI family of the periodic table onto the surface of a single or multi-quantum well structure composed of semiconductors; growing crystallites of a semiconductor or a metal by liquid-drop epitaxy; applying chemical etching to the single or multi-quantum well structure with the use of the crystallites as a mask, thereby removing areas of the single or multi-quantum well structure where the crystallites haven't grown on the surface; removing the crystallites used as mask by chemical etching; and filling a semiconductor into the areas of the single or multi-quantum well structure removed in the afore step.
