Abstract
Official abstract text for this publication.
An electrical component package includes a glass substrate, an interposer panel positioned on the glass substrate, the interposer panel comprising a device cavity, a wafer positioned on the interposer panel such that the device cavity is enclosed by the glass substrate, the interposer panel, and the wafer. The electrical component package further includes a metal seed layer disposed between the interposer panel and the wafer, and a dielectric coating. The dielectric coating hermetically seals the interposer panel to the glass substrate, the interposer panel to the metal seed layer and the wafer, and the interposer panel hermetically seals the metal seed layer to the glass substrate such that the device cavity is hermetically sealed from ambient atmosphere.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrical component package comprising: a glass substrate; an interposer panel positioned on the glass substrate, the interposer panel comprising a device cavity; a wafer positioned on the interposer panel such that the device cavity is enclosed by the glass substrate, the interposer panel, and the wafer; a metal seed layer disposed between the interposer panel and the wafer; and a dielectric coating, wherein the dielectric coating is an anti-reflective filter disposed on an external surface of the glass substrate, wherein the dielectric coating comprises at least a high optical index material and a low optical index material, and wherein the dielectric coating hermetically seals: the interposer panel to the glass substrate; and the interposer panel to the metal seed layer; and wherein the interposer panel hermetically seals the metal seed layer to the glass substrate such that the device cavity is hermetically sealed from ambient atmosphere. 2. The electrical component package of claim 1 , wherein at least a portion of the dielectric coating is disposed on at least a portion of a surface of the glass substrate within the device cavity. 3. The electrical component package of claim 1 , wherein at least a portion of the dielectric coating is disposed on sidewalls of the device cavity formed by the interposer panel. 4. The electrical component package of claim 3 , wherein at least a portion of the dielectric coating is disposed between the interposer panel and the glass substrate. 5. The electrical component package of claim 4 , wherein the portion of the dielectric coating disposed between the interposer panel and the glass substrate is within the device cavity. 6. The electrical component package of claim 5 , wherein the portion of the dielectric coating disposed between the interposer panel and the glass substrate is contiguous with the dielectric coating that is disposed on the sidewalls of the device cavity formed by the interposer panel. 7. The electrical component package of claim 1 , wherein the dielectric coating is disposed on an external surface of the glass substrate that is opposite the wafer. 8. The electrical component package of claim 1 , wherein a chromium aperture and an epoxy layer are disposed between the interposer panel and the glass substrate. 9. The electrical component package of claim 8 , wherein the chromium aperture is disposed directly on a surface of the glass substrate in the device cavity. 10. The electrical component package of claim 8 , wherein the epoxy layer comprises an epoxy layer aperture. 11. The electrical component package of claim 1 , wherein the dielectric coating on the external surface of the glass substrate comprises alternating high optical index materials and low optical index materials.
