Abstract:
A semiconductor pellet having a central area and a peripheral area, comprising:an integrated circuit formed in the central area of the pellet;a plurality of first electric pads arranged in a line in the peripheral area of the pellet, said first pads having a first width S1 and arranged with a first interval P; anda plurality of second electric pads connected to the conductive lines each of which has a second width L, said second pads having a third width S2 and located outside of said first pads in a parallel line to the line of said first pads with a second interval C,wherein the first, second and third widths S1, L, S2 and the first interval P has the following relationship:P>S2>S1+L;wherein each of said second pads are located at the positions corresponding to the middle positions between the first pads adjoining each other where said second pads are located in a first area which is inside of straight lines from a center of the semiconductor pellet having an angle e with a side of the semiconductor pellet, in which .theta.>tan.sup.-1 (2C/(P-S1)); andwherein each of said second pads are located at the positions shifting in a direction towards a corner of the semiconductor pellet from the middle positions where said second pads are located in a second area which is outside of the first area.
