Abstract
There is disclosed a method for chemically treating a display glass substrate by treating at least one surface of the glass substrate with a heated solution containing HCl to form a depletion layer at the surface and under the surface of the glass substrate. The disclosure also relates to display glass substrates containing the depletion layer made by the disclosed process. In addition, the disclosure relates to methods of making thin-film transistors ('TFTs') on these display glass substrates by depositing a Si layer directly on the chemically treated surface of the glass substrate, and annealing the Si layer to form polycrystalline silicon.
