Claim 8:
9. The preparation method of the LCoS panel of claim 8, wherein in the step C, manufacturing the plurality of vias comprises:
manufacturing a plurality of through holes extending through the first surface and the second surface in each of the plurality of die areas, the plurality of through holes exposing the plurality of input/output terminals;
manufacturing a dielectric layer covering inner walls of the plurality of through holes and a part of the second surface, etching the dielectric layer to expose the plurality of input/output terminals, thereby obtaining a patterned dielectric layer;
manufacturing a patterned conductive layer covering a part of the patterned dielectric layer, the patterned conductive layer covering the input/output terminals from the second surface, and a part of the patterned conductive layer extending to the second surface; and
manufacturing a pattern passivation layer covering a part of the patterned conductive layer from the second surface.
