Abstract
An electronic device is provided. The electronic device includes an inductor and a dielectric layer. The inductor includes a first magnetic layer, a conductive trace over the first magnetic layer, and a second magnetic layer over the conductive trace. The dielectric layer includes a first portion between the second magnetic layer and an inclined surface of the first magnetic layer. A substantially constant distance between the second magnetic layer and the inclined surface of the first magnetic layer is defined by the dielectric layer.
Claims20
An electronic device, comprising:
- an inductor comprising a first magnetic layer, a conductive trace over the first magnetic layer, and a second magnetic layer over the conductive trace;
- and
- a dielectric layer comprising a first portion between the second magnetic layer and an inclined surface of the first magnetic layer, wherein the dielectric layer further comprises a second portion connected to the first portion and having a bottom surface substantially level with a bottom surface of the first magnetic layer.
An electronic device, comprising:
- an inductor comprising a first magnetic layer, a conductive trace over the first magnetic layer, and a second magnetic layer over the conductive trace;
- and
- a buffer layer between the first magnetic layer and a peripheral portion of the second magnetic layer, wherein an elevation of a bottom surface of the peripheral portion of the second magnetic layer is higher than an elevation of a top surface of the first magnetic layer with respect to a top surface of the conductive trace.
