  • Patent number: 10392297
    Abstract: A method for manufacturing a substrate is disclosed. The method comprises the following steps: step one, depositing an amorphous silicon layer on a base material; step two, depositing a silicon dioxide layer with a first thickness on the amorphous silicon layer; and step three, etching the silicon dioxide layer until a thickness thereof is reduced to a second thickness. According to the method of the present disclosure, the silicon dioxide layer with a needed thickness can be manufactured on the amorphous silicon layer. When the ELA procedure is performed, the silicon dioxide layer has an enough thickness to prevent the formation of protrusions at grain boundary of polysilicon, so that the semi-conductive layer manufactured therein can have a relatively low roughness.
