Metal mesh lid MEMS package and method

1. A structure comprising:

a substrate;

a Micro Electro Mechanical Systems (MEMS) electronic component coupled to the substrate; and

a metal mesh lid coupled to the substrate, the metal mesh lid comprising:

a polymeric lid body having a top port formed therein; and

a metal mesh cap embedded within the polymeric lid body, wherein the metal mesh cap covers the top port such that air may flow through the top port.

2. The structure of claim 1 wherein the metal mesh lid further comprises: a lid plate parallel to the substrate; and

lid sidewalls extending perpendicularly from the lid plate and terminating at a lid base of the metal mesh lid.

3. The structure of claim 2 wherein the metal mesh cap is exposed from the polymeric lid body at the lid base.

4. The structure of claim 1 wherein the metal mesh cap comprises connected strands of electrically conductive material.

5. The structure of claim 4 wherein the metal mesh cap comprises holes therein through which external stimulus can pass.

6. The structure of claim 5 wherein the polymeric lid body seals the holes of the metal mesh cap.

7. The structure of claim 1 wherein the metal mesh cap forms a filtration structure that prevents contaminants from passing through the top port.

8. The structure of claim 1 further comprising a lid adhesive coupling the metal mesh lid to the substrate, wherein the metal mesh cap forms a locking feature for the lid adhesive.

9. The structure of claim 1 further comprising an electrically conductive lid adhesive coupling the metal mesh cap to ground terminals of the substrate.

10. A structure comprising:

a metal mesh lid array comprising:

a polymeric lid body array comprising lid bodies having top ports formed therein; and

a metal mesh cap array embedded within the polymeric lid body array, wherein metal mesh caps of the metal mesh cap array cover the top ports such that air may flow through the top ports.

11. The structure of claim 10 wherein the polymeric lid body array further exists between an inner surface of the polymeric lid body array and the metal mesh cap array.

12. The structure of claim 10 further comprising: substrates coupled to the metal mesh lid array.

13. The structure of claim 12 further comprising Micro Electro Mechanical Systems (MEMS) electronic components coupled to the substrates.

14. The structure of claim 12 wherein the metal mesh lid array further comprises:

lid plates parallel to the substrates; and

lid sidewalls extending perpendicularly from the lid plates and terminating at lid bases of the metal mesh lid array.
