Abstract
The present disclosure provides a semiconductor device. The semiconductor device includes a first inductor formed on a first substrate; a second inductor formed on a second substrate and conductively coupled with the first inductor as a transformer; and a plurality of micro-bump features configured between the first and second substrates. The plurality of micro-bump features include a magnetic material having a relative permeability substantially greater than one and are configured to enhance coupling between the first and second inductors.
