Abstract
A method of forming a germanium antimony tellurium (GeSbTe) layer includes forming a germanium antimony (GeSb) layer by repeatedly performing a GeSb supercycle; and forming the GeSbTe layer by performing a tellurization operation on the GeSb layer, wherein the GeSb supercycle includes performing at least one GeSb cycle; and performing at least one Sb cycle, the GeSbTe has a composition of Ge2Sb2+aTe5+b, in which a and b satisfy the following relations: −0.2<a<0.2 and −0.5<b<0.5.
