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 manufacturing a resonance device, comprising:
a) manufacturing a cover having a concavity;
b) providing a substrate;
c) locating plural microstructures on said substrate, wherein said plural microstructures comprise one non-testing microstructure and one testing element which is distinct from the non-testing microstructure;
d) locating a conducting element on said substrate for controlling said plural microstructures; and
e) packaging the plural microstructures in a vacuum by placing the cover over the plural microstructures to form said resonance device, wherein said concavity contains said testing element.
2. The method as claimed in claim 1 , wherein said step e) is performed by connecting said cover and said substrate.
3. The method as claimed in claim 1 , wherein said resonance device is an MEMS device.
4. The method as claimed in claim 1 , further comprising testing one or more properties of said resonance device using said testing element.
5. The method as claimed in claim 4 , wherein the one or more properties include a resonance frequency, a scanning angle, or a quality factor.
