Abstract: The present application provides a semiconductor substrate and a preparation process thereof. In the present application, the polysilicon layer includes the first polysilicon layer and the second polysilicon layer formed separately to generate the less stress, the more random grain orientation and the smaller grain size, maintain the high grain boundary density, and enhance the charge capture. By the combination of different deposition temperature and the combination of two cooling steps after each isothermal annealing treatment, the rate of contraction between the first polysilicon layer and the second polysilicon layer and the initial semiconductor substrate is decreased, and the thermal mismatch of semiconductor substrate is reduced. The stretch between the polysilicon layer and the initial semiconductor substrate can be reduced to prevent the warpage of the semiconductor substrate. Thereby, the stress generated during the growth process of the polysilicon layer can be further reduced.
