Abstract
A semiconductor device includes a main structure, active bumps and dummy bumps which are provided over a surface of the main structure. The active bumps are arranged in first to n-th rows. The active bumps positioned in each row are arrayed in a first direction with a predetermined first pitch. The first to n-th rows of the active bumps are arrayed in a second direction perpendicular to the first direction. For j being any integer from one to n−1, a (j+1)-th row are shifted in the second direction from a j-th row of the active bumps by a second pitch and shifted in the first direction from the j-th row of the active bumps by a predetermined sub-pitch. The dummy bumps are arrayed in the first direction with the first pitch, and the length of each of the dummy bumps in the second direction is longer than the second pitch.
