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 18):
The grating coupler structure of  claim 14 , wherein the second grating coupler pattern of the SiN material is a same pattern and aligned with the first grating coupler pattern of the polysilicon material and an SiN liner is directly contacting and over both the polysilicon material and the underlying dielectric material such that SiN liner is an intervening layer between the additional dielectric material and the polysilicon material.
