Abstract:
1. A method of forming a hinge, comprising: providing a wafer comprising a first surface and a second surface, the wafer defining at least a hinge region and at least two through regions, the two through regions being respectively positioned on two sides of the hinge region; removing parts of the wafer in the hinge region from the first surface of the wafer; removing the wafer in the two through regions from the second surface of the wafer until the wafer is removed through to the first surface so as to form a hinge, wherein the hinge and the wafer are monolithically-formed; performing a wafer level test on the wafer; and etching the wafer after the wafer level test so as to adjust a geometric shape of the hinge according to a test datum of the wafer level test.
