    • A method of manufacturing a thin film transistor, includes preparing a process chamber having a stage, providing a substrate on the stage of the process chamber, injecting a first mixed gas of NH3, N2 and SiH4 into the process chamber, forming a plasma in the process chamber and forming a silicon nitride film (SiNx) on the substrate, injecting a second mixed gas of H2 and SiH4 into the process chamber while removing the first mixed gas in the plasma state, forming a pure amorphous silicon film (a-Si:H) on the silicon nitride film using the second mixed gas, injecting a third mixed gas of H2, SiH4 and PH3 into the process chamber while removing the second mixed gas in the plasma state, and forming a doped amorphous silicon film (n+ a-Si:H) on the silicon nitride film using the second mixed gas.
    • 制造薄膜晶体管的方法包括制备具有级的处理室,在处理室的台上提供衬底,将NH 3,N 2和SiH 4的第一混合气体注入到处理室中,在第 在衬底上形成氮化硅膜(SiNx),在等离子体状态下除去第一混合气体,将H2和SiH4的第二混合气体注入到处理室中,形成纯非晶硅膜(a-Si: H)在使用第二混合气体的氮化硅膜上,在等离子体状态下除去第二混合气体,将H2,SiH4和PH3的第三混合气体注入到处理室中,形成掺杂的非晶硅膜(n + a- Si:H),使用第二混合气体。
