Semiconductor package having optimal interval between bond fingers for reduced substrate size

摘要

A semiconductor package includes a semiconductor chip having a plurality of bonding pads, and a substrate having a first surface on which a plurality of bond fingers are arranged and a second surface on which ball lands connected to the bond fingers are formed. The bond fingers are arranged in a plurality of rows, and are formed in the shape of a polygon, such that overlapping surfaces of a bond finger of a row, which overlap with another bond finger of another row, have a constant slope, and overlapping surfaces of bond fingers arranged in the same row, which face each other, are sloped in opposite directions. Bond fingers of each row are positioned between the overlapping surfaces of bond fingers of another row, which face each other, such that the bond fingers of the rows are arranged in a zigzag pattern.
