1. A semiconductor device comprising:
- a first substrate of a semiconductor die;
a first plurality of dielectric layers over a first side of the first substrate;
a first via extending through the first substrate and one or more of the first plurality of dielectric layers, the first via terminating in contact with a metal line of the semiconductor die; and
a second via extending through the first substrate and two or more of the first plurality of dielectric layers, the second via extending through more of the first plurality of dielectric layers than the first via and having a first end terminating at a first side of the semiconductor die and a second end terminating at a second side of the semiconductor die.

Abstract
A system and method for making semiconductor die connections with through-silicon vias (TSVs) are disclosed. A semiconductor die is manufactured with both via-first TSVs as well as via-last TSVs in order to establish low resistance paths for die connections between adjacent dies as well as for providing a low resistance path for feedthrough channels between multiple dies.
