Abstract:
1. A method of fabricating optical device caps, comprising: providing a wafer, and forming a plurality of through holes in the wafer; disposing a glass wafer on the wafer; providing a plate, and disposing the plate on the glass wafer, wherein the plate has a plurality of concave cavities respectively corresponding to the through holes of the wafer so that a part of the plate corresponding to the through holes is not in contact with the glass wafer; providing a voltage source, electrically connecting two electrodes of the voltage source respectively to the wafer and the plate so as to generate a voltage difference between the wafer and the plate, and using an anodic bonding method to bond the wafer to the glass wafer so that a plurality of optical device caps are formed; removing the plate from the glass wafer.
