Abstract:
A method of forming a semiconductor device comprising:providing a wafer having a plurality of semiconductor die, each semiconductor die of the plurality of semiconductor die having a surface and outer periphery X and outer periphery Y dimensions, the outer periphery X and outer periphery Y dimensions of each semiconductor die being perpendicular to each other;forming a plurality of electrical contacts on the surface of said each semiconductor die; andoverlying a plurality of package substrates over the plurality of semiconductor die, such that each package substrate of the plurality of package substrates is electrically connected to the plurality of electrical contacts of a respective semiconductor die of the plurality of semiconductor die, wherein: said each package substrate has outer periphery X' and outer periphery Y' dimensions being perpendicular to each other, and at least one of (i) the outer periphery X' dimension of said each package substrate is less than the X dimension of said respective semiconductor die, and (ii) the outer periphery Y' dimension of said each package substrate is less than the Y dimension of said respective semiconductor die.
