Abstract
Disclosed is an inductor device including a first curved metal plate, a second curved metal plate below and substantially vertically aligned with the first curved metal plate, and a first elongated via vertically aligned between the first curved metal plate and the second curved metal plate, the first elongated via configured to conductively couple the first curved metal plate to the second curved metal plate and having an aspect ratio of a width to a height of the first elongated via of at least approximately 2 to 1.
Claims15
An inductor device, comprising:
- a first curved metal plate;
- a second curved metal plate below and substantially vertically aligned with the first curved metal plate, wherein the second curved metal plate is substantially vertically aligned with the first curved metal plate for an entire length of the second curved metal plate except a terminal end of the second curved metal plate;
- a first elongated via vertically aligned between the first curved metal plate and the second curved metal plate, the first elongated via configured to conductively couple the first curved metal plate to the second curved metal plate and having an aspect ratio of a width to a height of the first elongated via of at least approximately 2 to 1;
- a third curved metal plate below and substantially vertically aligned with the second curved metal plate;
- and
- a second elongated via vertically aligned between the second curved metal plate and the third curved metal plate, the second elongated via configured to conductively couple the second curved metal plate to the third curved metal plate and having an aspect ratio of a width to a height of at least approximately 2 to 1,
- wherein the inductor device has no more curved metal plates than the first curved metal plate, the second curved metal plate, and the third curved metal plate,
- wherein each of the first curved metal plate, the second curved metal plate, and the third curved metal plate consists of a top metal layer and a bottom metal layer connected by a middle metal layer,
- wherein the bottom metal layer of the first curved metal plate forms a first terminal end of the inductor device and the bottom metal layer of the third curved metal plate forms a second terminal end of the inductor device, and
- wherein the inductor device has no more terminal ends than the first terminal end and the second terminal end.
