US Patent 11189563 Semiconductor structure and manufacturing method thereof

The semiconductor structure includes a first die, a second die, a connecting portion, and a through-substrate via. The first die includes a first dielectric layer and a first helical conductor embedded therein. The second die includes a second dielectric layer and a second helical conductor embedded therein, wherein the second dielectric layer is bonded with the first dielectric layer, thereby forming an interface. The connecting portion extends from the first dielectric layer through the interface to the second dielectric layer and interconnects the first helical conductor with the second helical conductor. The through-substrate via extends from the first die to the second die through the interface, wherein the through-substrate via is surrounded by the first and the second helical conductors.
