Abstract
In a wafer having a plurality of integrated circuit chips of different chip sizes formed on the wafer, each of the integrated circuit chips having a number of externally connecting lands uniformly distributed over the whole surface of the chip with equal pitches to depict a matrix or a repeated pattern of an equilateral triangle, a plurality of power supply lands of the externally connecting lands are located to depict a cross having a crossing point positioned at a center of the chip. A geometrical location of the power supply lands is congruent to all said integrated circuit chips of different chip sizes. The pitch between adjacent lands positioning a dicing line therebetween is one obtained by multiplying the pitch between adjacent lands positioning no dicing line therebetween, by a positive integer.
