Abstract

This invention provides an optoelectronic interconnect structure and its fabrication method. The aim is to obtain a first substrate with an optical interconnect network and a second substrate with an electrical interconnect network by separately placing optical interconnect networks and electrical interconnect networks on different core layers. The first substrate with the optical interconnect network and the second substrate with the electrical interconnect network are then interconnected to obtain a substrate that possesses both optical and electrical interconnect functions. This ensures that the fabrication processes of the optical interconnect network and the electrical interconnect network do not interfere with each other, avoiding the risk of substrate warping and increasing the flexibility of wiring for the electrical interconnect network used for electrical interconnect functions.
