The via is in a shape of a circle, rectangle, square, rhombus, triangle with one side being close to the second side, or triangle with one angle being close to the second side. The via has a maximum length in a direction parallel to the first side being ¼ to ¾ times a length of the first side, and a maximum length in a direction perpendicular to the first side being ¼ to ¾ times a length from the first side to the second side.
