摘要： Provided is a method of manufacturing a semiconductor device. The method of manufacturing the semiconductor device includes forming magneto tunnel layers, forming a hard mask on the magneto tunnel layers, etching the magneto tunnel layers to form a magneto tunnel junction, wherein etching by-products are formed on sidewalls of the magneto tunnel junction, performing chemical treatment on the etching by-products to convert the etching by-products into a chemical reactant; and inspecting the chemical reactant.
