1. , a kind of manufacture method of thin-film transistor comprises:

  • Form conductive layer on substrate;

    Form pattern mask on this conductive layer, to be covered in the zone of desire formation thin-film transistor on this substrate;

    Remove not this conductive layer by this pattern mask covered;

    Divest legal adopted laser hole in this pattern mask with laser, with this conductive layer of exposed portions serve, and this laser hole forms the channel region of this thin-film transistor corresponding to desire;

    AndThis conductive layer that this laser hole of etching is exposed is to form drain electrode and source electrode in the both sides of this channel region.
