Patent ID: 8367482

Claim:
A method for fabricating contacts of a semiconductor device structure, comprising: forming a dielectric layer over a semiconductor substrate with active-device regions spaced at a first pitch; forming a first plurality of substantially in-line apertures over every second active-device region of the active-device regions, a distance across at least an upper portion of each aperture of the first plurality exceeding a width of a corresponding active-device region; forming a second plurality of substantially in-line apertures laterally offset from the apertures of the first plurality over active-device regions over which the apertures of the first plurality are not located, a distance across at least an upper portion of each aperture of the second plurality exceeding a width of a corresponding active-device region; forming a contact plug in each aperture of the first plurality of apertures and the second plurality of apertures; disposing another dielectric material over the contact plugs formed in each aperture of the first plurality of apertures and the second plurality of apertures; forming a plurality of laterally extending trenches in the another dielectric material, comprising: extending a portion of each laterally extending trench of the plurality of laterally extending trenches to the contact plug in each aperture of one of the first plurality of apertures and the second plurality of apertures; and sizing each laterally extending trench of the plurality of laterally extending trenches such that the portion of the laterally extending trench at the contact plug exhibits a distance across the laterally extending trench that is less than a distance across a portion of the contact plug at the laterally extending trench; and fanning a conductive line in each laterally extending trench of the plurality of laterally extending trenches.
