Patent ID: 7869188

Claim:
A capacitor structure comprising: an insulating layer; first and second conductive patterns alternately arranged on the insulating layer and spaced apart from one another, the first and second conductive patterns having side faces where concave portions and convex portions are formed; an insulating interlayer formed on the insulating layer to cover the first and second conductive patterns; and third and fourth conductive patterns alternately arranged on the insulating interlayer and spaced apart from one another, the third and fourth conductive patterns having side faces where concave portions and convex portions are formed, wherein the first and second conductive patterns extend in a first direction, the first and second conductive patterns being alternately arranged to be spaced apart from one another in a second direction substantially perpendicular to the first direction, the first and second conductive patterns having a zigzag shape alternately extending in third and fourth directions, the third direction being rotated clockwise from the first direction by a first angle of between about 0° and about 90°, and the fourth direction being rotated counterclockwise from the first direction by a second angle of between about 0° and about 90°; and wherein the third and fourth conductive patterns are substantially symmetric with respect to central axes of the first and second conductive patterns, respectively.
