The present invention provides a method for manufacturing an LTPS TFT substrate structure and a structure of an LTPS TFT substrate. The method for manufacturing the LTPS TFT substrate structure according to the present invention provides patterns of a thermally conductive electrical-insulation layer that are of the same size and regularly distributed under a buffer layer of a driving TFT area to absorb heat in a subsequent excimer laser annealing process so as to speed up the cooling rate of amorphous silicon to form crystal nuclei that gradually grow up in the annealing process. Since the thermally conductive electrical-insulation layer is made up of regularly distributed and size-consistent patterns, crystal grains of a polycrystalline silicon layer located in the driving TFT area show improved consistency and homogeneity and the grain sizes are relatively large to ensure the consistency of electrical property of the driving TFT.
