Abstract: An approach for providing MOL constructs using diffusion contact structures is disclosed. Embodiments include: providing a first diffusion region in a substrate; providing, via a first lithography process, a first diffusion contact structure; providing, via a second lithography process, a second diffusion contact structure; and coupling the first diffusion contact structure to the first diffusion region and the second diffusion contact structure. Embodiments include: providing a second diffusion region in the substrate; providing a diffusion gap region between the first and second diffusion regions; providing the diffusion contact structure over the diffusion gap region; and coupling, via the diffusion contact structure, the first and second diffusion regions.
