Abstract
An integrated circuit comprising both memory and logic wherein at least one layer of the integrated circuit is fabricated using a common grating pattern for both memory and logic is described. In one embodiment, the integrated circuit comprises a substrate, an active layer, and a gate material layer such as a polysilicon layer, and the active layer, the gate material layer, or both the active layer and the gate material layer are formed using a common grating pattern for both memory and logic. By using a common grating pattern for both memory and logic, a corresponding layer of the integrated circuit can be reliably and affordably manufactured using sub-wavelength lithography.
