Patent ID: 8202764

Claim:
A method of manufacturing a semiconductor package, the method comprising: forming a plurality of semiconductor chips (F) having the same pattern direction on a semiconductor substrate, wherein each of the semiconductor chips comprises a memory cell region, a peripheral region, and a pad region, wherein the pad region of each semiconductor chip is disposed at a corner of the semiconductor chip; separating each of the plurality of semiconductor chips from one another; and disposing selected semiconductor chips, from the separated semiconductor chips, on a package substrate, including changing the pattern directions of a subset of the selected semiconductor chips such that the relative orientations of each semiconductor chip in the subset of the selected semiconductor chips is different on the package substrate than it was on the semiconductor substrate and the pad regions of the selected semiconductor chips are arranged to be adjacent to each other in a center region of the package substrate located between the selected semiconductor chips, wherein forming each of the plurality of semiconductor chips comprises: forming the memory cell region in a center region of the semiconductor chip; forming the peripheral region in each of row and column directions of the memory cell region; and forming the pad region adjacent to a corner of the memory cell region; and wherein disposing selected semiconductor chips on the package substrate comprises: disposing a first semiconductor chip, from the selected semiconductor chips, on the package substrate such that a pad region of the first semiconductor chip is placed in the center region of the package substrate; and rotating a second semiconductor chip, from the selected semiconductor chips, at least 90 degrees with respect to the first semiconductor chip and disposing the second semiconductor chip such that a pad region of the second semiconductor chip is adjacent to the pad region of the first semiconductor chip.
