Patent ID: 7208345

Claim:
A method of manufacturing of a semiconductor device having stacked chips comprising: forming a first reconstituted wafer having a first plurality of chips horizontally separated by a first gap filled with a mould, wherein contact pads of the first chips are arranged in an active surface of the first reconstituted wafer; forming a first redistribution layer on the active surface of the first reconstituted wafer, the first redistribution layer contacting contact pads of first chips and extending on the mould; forming a second reconstituted wafer having a second plurality of chips horizontally separated by a second gap filled with a mould, wherein contact pads of the second chips are arranged in an active surface opposite to a back side of the second reconstituted wafer; dicing the second reconstituted wafer along the second gap such that individualized embedded chips are formed having tilted sidewalls defining an angle of more than ninety degrees with respect to the active surface of the second reconstituted wafer; placing the embedded chips with their back side on the active surface of the first reconstituted wafer and the first redistribution layer; and forming a second redistribution layer on the active surface of the embedded chips and tilted sidewalls the second redistribution layer connecting contact pads of the second chips with the first redistribution layer.
