Abstract:
1. A circuit board comprising: bonding pads for being connected with bumps of a semiconductor element, which act as connection terminals, the bonding pads being arrayed in parallel lines on a surface of the circuit board, and on the parallel lines that are adjacent to each other, the bonding pads being positioned to form a zigzag pattern along the parallel lines longitudinally, the bonding pads being further positioned so that (i) adjacent ones of bonding pads, arrayed in each of the parallel lines, are separated from each other by a pitch P, (ii) adjacent ones of bonding pads, positioned oppositely and alternatively in adjacent ones of the parallel lines respectively, are separated by a distance S, and (iii) the pitch P and the distance S are substantially equal to each other.
