Patent ID: 8049258

Claim:
A memory device, comprising a first component grouping comprising, as seen in plan view: a first elongate active area defining a first axis, the first active area comprising a first source and at least first and second drains; at least two substantially parallel word lines that cross and overlie the first active area, at least a portion of a first word line located between the first drain and the first source, at least a portion of a second word line located between the second drain and the first source; and a first plurality of contact plugs on the same vertical level as the word lines, the contact plugs comprising rhomboid portions of conductive material, the first plurality of contact plugs contacting and generally overlying the first active area, at least one of the first plurality of contact plugs extending between the at least two word lines and at least one of the first plurality of contact plugs extending outwardly from either word line, each of the first plurality of contact plugs being aligned with the first axis; and second component grouping comprising, as seen in plan view: a second elongate active area defining a second axis, the second active area comprising a second source and third and fourth drains; at least two substantially parallel word lines that cross and overlie the second active area, at least a portion of a third word line located between the third drains and the second source, at least a portion of a fourth word line located between the fourth drain and the second source; and a second plurality of contact plugs on the same vertical level as the word lines, the contact plugs comprising rhomboid portions of conductive material, the second plurality of contact plugs contacting and generally overlying the second active area, at least one of the second plurality of contact plugs extending between the third and fourth word lines and at least one of the second plurality of contact plugs extending outwardly from each of the third and fourth wordlines, each of the second plurality of contact plugs being aligned with the second axis; wherein the second axis has a slope that is opposite in sign that of the first axis when the axes are considered in plan view.
