Electrical interconnects for packages containing photonic integrated circuits

Abstract

A semiconductor chip includes: a photonic integrated circuit (PIC) comprising an active component electrically connected to a first landing pad at a surface of the PIC, wherein the first landing pad is configured to receive a copper pillar, which, when installed, provides at least a portion of a first electrical interconnect between the active photonic component and a second integrated circuit to be stacked on the surface of the PIC, and wherein, when viewed from above the PIC towards the PIC, a center of the active photonic component on the PIC is offset from a nearest edge of the first landing pad by about a distance less than 10 μm.

Dependencies are inferred from the claim text.
