  We describe the design and fabrication of a scalable atom-light photonic
interface based on a silicon nitride microring resonator on a transparent
silicon dioxide-nitride multi-layer membrane. This new photonic platform is
fully compatible with freespace cold atom laser cooling, stable trapping, and
sorting at around $100~$nm from the microring surface, permitting the formation
of an organized, strongly interacting atom-photonic hybrid lattice. We
demonstrate small radius ($R\sim$16$\mu$m) microring and racetrack resonators
with a high quality factor $Q=3.2\times 10^5$, projecting a single atom
cooperativity parameter of $C=25$ and a vacuum Rabi frequency of $2g=
2\pi\times 340~$MHz for trapped cesium atoms interacting with a microring
resonator mode. We show that the quality factor is currently limited by the
surface roughness of the multi-layer membrane, grown using low pressure
chemical vapor deposition (LPCVD) processes. We discuss possible further
improvements to a quality factor above $Q>5\times10^6$, potentially achieving
single atom cooperativity parameter of $C > 500$ for strong single atom-photon
coupling.
