Method of embedding passive component within via
View Patent ↗A method of forming a device associated with a via includes forming an opening or via, and forming at least a pair of conducting paths within the via. Also disclosed is a via having at pair of conducting paths therein.
1. A device comprising:
a first conductive layer;
a second conductive layer;
a dielectric material formed between the first conductive layer and the second conductive layer;
an opening extending through a portion of the dielectric material, wherein the opening further comprises:
a first metal layer located on a first portion of the opening; and
a second metal layer located on a second portion of the opening, wherein the first metal layer electrically connects a first portion of the first conductive layer to a first portion of the second conductive layer and wherein the second metal layer electrically connects a second portion of the first conductive layer to a second portion of the second conductive layer through the opening in the dielectric material and wherein the second metal layer is electrically isolated from the first metal layer.
2. The device of claim 1 wherein a second dielectric material is disposed between the first metal layer and the second metal layer.
3. The device of claim 1 wherein there is a first electrical path from the first conductive layer to the first metal layer.
4. The device of claim 1 wherein there is a second electrical path from the second conductive layer to the second metal layer.
5. The device of claim 1 wherein the first metal layer and the second metal layer comprise a portion of a capacitor.
6. The device of claim 5 wherein the capacitor connects a portion of the first conductive layer to a portion of the second conductive layer.
7. The device of claim 5 wherein the capacitor is embedded within a portion of a substrate.
8. The device of claim 1 wherein the opening comprises a portion of a via opening.
9. The device of claim 1 wherein none of a material of the first metal layer is located on the second portion of the opening.
10. The device of claim 1 wherein none of a material of the second metal layer is located on the first portion of the opening.
11. The device of claim 1 wherein the first conductive layer and the second conductive layer comprise a portion of a package substrate.
