Multilayered network of power supply lines

An apparatus comprising:

• a plurality of first power electrode patterns and a plurality of second power electrode patterns alternately arranged in a first direction;
• a plurality of first power lines and a plurality of second power lines extending in a second direction substantially perpendicular to the first direction, wherein two first power lines of the plurality of first power lines and two second power lines of the plurality of second power lines are alternately arranged in the first direction;
• a plurality of first via electrode groups each including a plurality of first via electrodes each connecting an associated one of the first power lines to an associated one of the first power electrode patterns;
• and
• a plurality of second via electrode groups each including a plurality of second via electrodes each connecting an associated one of the second power lines to an associated one of the second power electrode patterns,
• wherein the first via electrodes included in each of the first via electrode groups are arranged in the second direction, and
• wherein the second via electrodes included in each of the second via electrode groups are arranged in the second direction.

An apparatus comprising:

• a plurality of first power electrode patterns and a plurality of second power electrode patterns alternately arranged in a first direction;
• a plurality of pairs of first power lines and a plurality of pairs of second power lines extending in a second direction substantially perpendicular to the first direction, the pairs of first and second power lines being alternately arranged in the first direction;
• a plurality of first via conductors disposed in the first direction, each first via conductor connecting one of an associated one of pairs of the first power lines to an associated one of the first power electrode patterns;
• a plurality of second via conductors disposed in the first direction, each second via conductor connecting other of an associated one of pairs of the first power lines to an associated one of the first power electrode patterns;
• a plurality of third via conductors disposed in the first direction, each third via conductor connecting one of an associated one of pairs of the second power lines to an associated one of the second power electrode patterns;
• and
• a plurality of fourth via conductors disposed in the first direction, each fourth via conductor connecting other of an associated one of pairs of the second power lines to an associated one of the second power electrode patterns.
