Abstract
A current sense resistor integrated with an integrated circuit die housed in a chip-scale semiconductor package includes a metal layer formed over a passivation layer of the integrated circuit die where the metal layer having an array of metal pillars extending therefrom. The metal pillars are to be electrically connected to a first conductive electrode and a second conductive electrode external to the chip-scale semiconductor package where the first conductive electrode and the second conductive electrode are physically separated from each other by a separation of a first distance. The current sense resistor is formed in a portion of the metal layer spanning the separation between the first and second conductive electrodes. In some embodiments, a semiconductor device including an integrated circuit die housed in a chip-scale semiconductor package includes a current sense resistor formed in a metal layer formed over a passivation layer of the integrated circuit die.
