Abstract:
A method for forming CA power rails using a three mask decomposition process and the resulting device are provided. Embodiments include forming a horizontal diffusion CA power rail in an active layer of a semiconductor substrate using a first color mask; forming a plurality of vertical CAs in the active layer using second and third color masks, the vertical CAs connecting the CA power rail to at least one diffusion region on the semiconductor substrate, spaced from the CA power rail, wherein each pair of CAs formed by one of the second and third color masks are separated by at least two pitches.
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.
