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 14):
A grating coupler structure, comprising:\n a semiconductor material; a polysilicon material directly contacting an underlying dielectric material and completely embedded in additional dielectric material which is over the semiconductor material and the underlying dielectric material, and the polysilicon material having a first grating coupler pattern; a SiN material entirely embedded in and contacting the additional dielectric material such that the SiN material is completely surrounded by and in direct contact with the additional dielectric material, and the SiN material is further located over the polysilicon material separated from the polysilicon material by the additional dielectric material such that the additional dielectric material is between the SiN material and the polysilicon material, and the SiN material having a second grating coupler pattern which directs light through the first gating coupler pattern of the polysilicon material; and wiring or interconnect structures over the additional dielectric material.
