Integration manufacturing process for MEMS device
View Patent ↗A method for manufacturing an MEMS device is provided. The method includes steps of a) providing a first substrate having a concavity located thereon, b) providing a second substrate having a connecting area and an actuating area respectively located thereon, c) forming plural microstructures in the actuating area, d) mounting a conducting element in the connecting area and the actuating area, e) forming an insulating layer on the conducting element and f) connecting the first substrate to the connecting area to form the MEMS device. The concavity contains the plural microstructures.
1. A method for testing an airtightness of a resonance device, comprising steps of:
a) locating a testing component on a lower substrate of said resonance device;
b) packaging said lower substrate by a cover in a vacuum;
c) testing said resonance device under a predetermined environment and judging said airtightness of said resonance device by a property performed by said testing component in the predetermined environment.
2. The method as claimed in claim 1 , wherein said testing component is one of a minor and a cantilever.
3. The method as claimed in claim 1 , wherein said step a) further comprises steps of: a1) locating a conducting device on said lower substrate; a2) forming an insulating layer on said conducting element; and a3) forming a metal connecting layer on said insulating layer.
4. The method as claimed in claim 3 , wherein said metal connecting layer is used for connecting said cover to said lower substrate in said step b).
5. The method as claimed in claim 1 , wherein step a) further comprises locating a non-testing component on the lower substrate.
6. The method of claim 2 , wherein step c) includes driving the testing device into its resonance state and testing the amplitude of the resonance state using a Doppler measuring device.
