Provided are a Ge precursor for low temperature deposition containing Ge, N, and Si, a GST thin layer doped with N and Si formed using the same, a memory device including the GST thin layer doped with N and Si, and a method of manufacturing the GST thin layer. The Ge precursor for low temperature deposition contains N and Si such that the temperature at which the Ge precursor is deposited to form a thin layer, particularly, the GST thin layer doped with N and Si, can be low. In addition, during the low temperature deposition, H2 plasma can be used. The GST phase-change layer doped with N and Si formed from the Ge precursor for low temperature deposition has a low reset current. Therefore, a memory device including the GST phase-change layer doped with N and Si can be highly integrated, have a high capacity, and can be operated at a high speed.
提供了一种低温沉积的含有Ge、N和Si的Ge前体,使用相同的Ge前体形成掺杂有N和Si的GST薄层,包括掺杂有N和Si的GST薄层的存储器件,以及制造GST薄层的方法。低温沉积的Ge前体含有N和Si,使得Ge前体沉积形成薄层的温度,特别是掺杂有N和Si的GST薄层的温度可以很低。此外,在低温沉积过程中,可以使用H2等离子体。从低温沉积的Ge前体形成的掺杂有N和Si的GST相变层具有低复位电流。因此,包括掺杂有N和Si的GST相变层的存储器件可以高度集成,具有高容量,并且可以以高速运行。
