Abstract

Embodiments described herein provide techniques of forming an interconnect structure using lithographic and deposition processes. The interconnect structure can be used to couple components of a semiconductor package. For one example, a semiconductor package includes a die stack and an interconnect structure formed on the die stack. The die stack comprises a plurality of dies. Each die in the die stack comprises: a first surface; a second surface opposite the first surface; sidewall surfaces coupling the first surface to the second surface; and a pad on the first surface. A one sidewall surface of one of the dies has a sloped profile. The semiconductor package also includes an interconnect structure positioned on the first surfaces and the sidewall with the sloped profile. In this semiconductor package, the interconnect structure electrically couples the pad on each of the dies to each other.
