    摘要: Provided are a method of forming an insulating layer and a method of manufacturing a transistor using the method. The method of forming the insulating layer includes forming a preliminary insulating layer including silicon oxide (SiO2) on a silicon (Si)-containing substrate. A reactive gas containing ammonia (NH3) gas is supplied to the preliminary insulating layer. Nitrogen radicals (N*) and hydrogen radicals (H*) are generated from the ammonia gas using plasma. The hydrogen radicals combine with oxygen of the preliminary insulating layer, and the nitrogen radicals combine with the silicon oxide so that an insulating layer including hydroxides (OH) and silicon oxynitride (SiON) can be formed.

    摘要: In semiconductor devices, methods of forming the same, the semiconductor device include a first gate structure having a first gate oxide layer pattern, a first polysilicon layer pattern containing atoms larger than silicon and a first hard mask layer pattern on substrates under tensile stress. N-type impurity regions are formed under the surface of the substrate on both sides of the first gate structure. A second gate structure having a second gate oxide layer pattern, a second polysilicon layer pattern containing atoms smaller than silicon and a second hard mask layer pattern on substrates under compressive stress. Additionally, P-type impurity regions are formed under the surface of the substrate on both sides of the second gate structure. The semiconductor devices have good device properties.
