Patent ID: 8763243

Claim:
A method for fabricating a substrate board, comprising: providing a substrate layer; patterning the substrate layer to form a substrate having a first surface and a second surface opposite to the first surface and comprising at least a plurality of rigid areas and a plurality of flexible areas, wherein each of the rigid areas is thicker than the flexible areas, and the substrate further has a plurality of recesses separately distributed on the second surface so as to define the rigid areas and the flexible areas; fabricating a plurality of electronic components on the first surface of the substrate, wherein a portion of the electronic components located in the rigid areas are thicker than the rest of the electronic components located in the flexible areas; and forming a patterned high-extensive material layer on the second surface of the substrate, wherein patterning the substrate layer comprises: forming a patterned material layer; forming the substrate layer on the patterned material layer; and separating the substrate layer from the patterned material layer to form the rigid areas and the flexible areas on the substrate.
