Through-chip conductors for low inductance chip-to-chip integration and off-chip connections

摘要

Through-chip conductors for low inductance chip-to-chip integration and off-chip connections in a semiconductor package is disclosed. A semiconductor device has active devices on the front surface, a first through-chip conductor having first electrical/physical characteristics passing from the front surface of the device to the back surface, a second through-chip conductor having second electrical/physical characteristics passing to the back surface, and an off-chip or chip-to-chip connector electrically connecting the active devices on the front surface to a different level of packaging.
