Sealed package including electronic device and power source
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.
1 . A method of forming a hermetically-sealed package, comprising:
disposing a power source at least partially within a housing;
disposing an electronic device on a major surface of a substantially transparent substrate;
hermetically sealing the substrate to the housing, wherein a non-bonded electrical connection is formed between a device contact of the electronic device and a power source contact of the power source when the substrate is hermetically sealed to the housing, wherein hermetically sealing the substrate to the housing comprises laser bonding the major surface of the substrate to the housing.
2 . The method of claim 1 , further comprising disposing one or more electrodes on a second major surface of the substrate.
3 . The method of claim 2 , further comprising:
forming a via between the major surface and the second major surface of the substrate; and
electrically connecting the one or more electrodes to the electronic device through the via.
4 . The method of claim 1 , wherein the housing further comprises a flange surrounding a cavity of the housing, wherein hermetically sealing the substrate to the housing comprises hermetically sealing the substrate to the flange of the housing.
5 . The method of claim 1 , wherein the electronic device is disposed in a cavity of the housing between the substrate and an inner surface of the housing when the substrate is hermetically sealed to the housing.
6 . The method of claim 1 , further comprising:
disposing an antenna on a second major surface of the substrate; and
electrically connecting the electronic device to the antenna.
7 . The method of claim 6 , wherein electrically connecting the electronic device to the antenna comprises forming a via between the major surface and the second major surface of the substrate such that the electronic device is electrically connected to the antenna through the via.
