Patent ID: 7960797

Claim:
A semiconductor device structure, comprising: a plurality of active-device regions having a first pitch; a first row of substantially aligned contacts spaced at a second pitch that exceeds the first pitch, each contact of the first row of substantially aligned contacts comprising: a lower contact plug contacting a corresponding active-device region and including: a narrow base, with a distance across the narrow base being about the same as a corresponding distance across the corresponding active-device region; and a wide upper surface, with a distance across the wide upper surface being at least about twice the distance across the narrow base; and an upper contact plug above the lower contact plug, with a base of the upper contact plug contacting the wide upper surface of the lower contact plug, a distance across the base of the upper contact plug being smaller than the distance across the wide upper surface of the lower contact plug; and a second row of substantially aligned contacts laterally offset from the first row of substantially aligned contacts and spaced at the second pitch.
