Abstract
In accordance with an embodiment, a semiconductor device comprises a semiconductor die, an interposer, and conductive bumps bonding the semiconductor die to the interposer. The semiconductor die comprises a first metallization layer, and the first metallization layer comprises a first conductive pattern. The interposer comprises a second metallization layer, and the second metallization layer comprises a second conductive pattern. Some of the conductive bumps electrically couple the first conductive pattern to the second conductive pattern to form a coil. Other embodiments contemplate other configurations of coils, inductors, and/or transformers, and contemplate methods of manufacture.
