Abstract:
1. 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: fanning a conductive line in each laterally extending trench of the plurality of laterally extending trenches.
