Since the silicon wafer is in the rectangular blind hole on the top of the sunken base 71, there is a certain gap with the silicon wafer of the adjacent stabilizing frame 7, so there will be no collision to cause damage to the silicon wafer.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
