Latest Patents

Hai Song holds 1 patent for his work titled "Methods for Polysilicon Characterization." This patent outlines a method that includes receiving image data of a polysilicon structure formed on a sample substrate. The image data is generated by transmission electron microscopy (TEM) and is in a spatial domain. The method further involves extracting the frequency spectrum of the image data in a frequency domain. Additionally, it includes selecting a subset of the frequency spectrum that corresponds to the characteristics of first crystal grains that are of a first orientation. Finally, the method transforms the selected subset of the frequency spectrum back to the spatial domain to construct a first spatial image for the first crystal grains of the first orientation.
