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 21):
The grating coupler structure of  claim 1 , further comprising an SiN liner directly on a surface and lining the polysilicon material and the underlying insulator material, wherein the polysilicon material is directly on the underlying insulator material and the SiN material is surrounded by the dielectric material including between the SiN material and the SiN liner.
