Abstract:
The present disclosure relates to semiconductor structures and, more particularly, to grating couplers with multiple configurations and methods of manufacture. A grating coupler structure includes: a polysilicon material with a first grating coupling pattern; a SiN material with second grating coupling pattern; a dielectric material covering the polysilicon material and the SiN material; and a back end of line (BEOL) multilayer stack over the dielectric material.

Claim (Index 1):
A grating coupler structure, comprising:\n a polysilicon material with a first grating coupling pattern directly contacting an underlying insulator material; a SiN material with a second grating coupling pattern located above the polysilicon material; a dielectric material covering the polysilicon material and completely surrounding the SiN material; and wiring or interconnect structures over the dielectric material, wherein the first grating coupling pattern and the second grating coupling pattern are a same pattern.
