Abstract

Various embodiments of a sealed package and method of forming such package are disclosed. The package can include a housing having an inner surface and an outer surface, and a substrate having a first major surface and a second major surface. The package can also include an electronic device disposed on the first major surface of the substrate, and a power source disposed at least partially within the housing. The substrate can be sealed to the housing such that a non-bonded electrical connection is formed between a device contact of the electronic device and a power source contact of the power source.

First claim

What is claimed is:

1. A hermetically-sealed package, comprising:
a housing comprising an inner surface, an outer surface, and a cavity;
a non-conductive substrate comprising a first major surface and a second major surface, wherein the non-conductive substrate is substantially transparent;
an electronic device disposed on the first major surface of the substrate and comprising a device contact;
a power source disposed at least partially within the cavity of the housing and comprising a resilient power source contact; and
an electrode disposed on the second major surface of the substrate, wherein the electrode is electrically connected to the electronic device by a via formed between the first major surface and the second major surface of the substrate;
wherein the substrate is hermetically sealed to the housing by a laser bond such that a non-bonded electrical connection is formed within the cavity of the housing between the device contact and the resilient power source contact.

2. The package of claim 1 , wherein the power source further comprises a retaining member that is in contact with the inner surface of the housing and stabilizes the power source relative to the inner surface of the housing.

3. The package of claim 2 , wherein the retaining member provides a friction-fit between the power source and the inner surface of the housing.

4. The package of claim 2 , wherein the retaining member comprises a spring plate disposed on the power source.

5. The package of claim 1 , wherein the housing forms at least a portion of an outer casing of the power source.

6. The package of claim 1 , wherein the housing comprises a flange surrounding the cavity of the housing, wherein the substrate is hermetically sealed to the flange.

7. The package of claim 1 , wherein the first major surface of the substrate is hermetically sealed to the housing such that the electronic device is disposed in the cavity between the substrate and the inner surface of the housing.

8. The package of claim 1 , further comprising an antenna disposed on the second major surface of the substrate and electrically connected to the electronic device by a via formed between the first major surface and the second major surface of the substrate.

9. The package of claim 1 , further comprising an antenna disposed within the substrate and electrically connected to the electronic device by a via formed between the antenna and the first major surface of the substrate.

10. The package of claim 1 , wherein the electronic device comprises a multiplexer.

11. The package of claim 1 , wherein the electronic device comprises a controller.

12. The package of claim 1 , wherein the electronic device comprises an implantable medical device.

13. The package of claim 1 , wherein the power source comprises a battery.

14. The package of claim 1 , wherein the power source contact comprises positive and negative terminals disposed at a first end of the power source.

15. The package of claim 1 , wherein the non-conductive substrate is substantially transmissive to light having a wavelength of between 200 nm to 10,000 nm.

16. The package of claim 1 , wherein the non-conductive substrate comprises at least one of glass, quartz, silica, sapphire, silicon carbide, diamond, or gallium nitride, or any combinations thereof.

17. The package of claim 1 , wherein the housing comprises at least one of glass, quartz, silica, sapphire, silicon carbide, diamond, MP35N, or gallium nitride.

18. The package of claim 1 , wherein the electrode comprises a first electrode, wherein the package further comprises a second electrode disposed on the second major surface of the non-conductive substrate.

19. The package of claim 18 , wherein the second electrode is electrically connected to the electronic device by a via formed between the first major surface and the second major surface of the non-conductive substrate.

20. The package of claim 18 , wherein the first and second electrodes are adapted to at least one of deliver or receive electrical signals to or from a patient.
