  • Patent number: 6200837
    Abstract: A method of manufacturing a TFT which can improve realibility by planarizing the surface of a polysilicon layer as a channel layer, is disclosed. According to the present invention, an amorphous silicon layer is formed on an insulating layer substrate and crystallized by excimer layer annealing process, to form a polysilicon layer. Next, the surface of the polysilicon layer is oxidized to form an oxide layer. At this time the sufrace of the polsyilicon under the oxide layer become smooth. Preferably, the oxide layer is formed by oxiation process using ECR (Electron Cyclon Resonator) plasma or using one selected from the group consisting of O2, O2N2, O2N2O, O2NH3 and NO. Thereafter, the oxide layer is removed to expose the polysilicon layer and then a gate insulating layer is formed on the exposed polysilicon layer. Preferably, the gate insulating layer is formed to one selected from the group consisting of a SiO2 layer, a SiN layer, a SiON layer and a TEOS oxide layer.
