A semiconductor device having a semiconductor substrate is provided. The semiconductor substrate includes an integrated circuit, which includes multi-layer structured metallization and inter-metal dielectric. The integrated circuit is below a passivation, which is over a metal structure. The metal structure includes a metal pad and an under bumper metallurgy, which is over and aligned with the metal pad. The metal pad is electrically connected to the integrated circuit, and the under bumper metallurgy is configured to electrically connect to a conductive component of another semiconductor device. The integrated circuit further includes a conductive trace, which is below and aligned with the metal structure. The conductive trace is connected to a power source such that an electromagnetic field is generated at the conductive trace when an electric current from the power source passes through the conductive trace.
