Abstract:
1. A microelectronic assembly comprising: at least first and second microelectronic elements each having a front face arranged in a common plane and arranged side by side in a molded structure, each of the microelectronic elements having a plurality of element contacts at the front face, each of the element contacts having a first dimension in a first direction parallel to the common plane and having a second dimension in a second direction parallel to the common plane, the first direction being transverse to the second direction, the first dimension being at least twice the second dimension; a dielectric layer extending along the front face of each of the first and second microelectronic elements and onto an intermediate surface between adjacent edges of the first and second microelectronic elements; and a conductive redistribution layer including first and second conductive vias extending through the dielectric layer to first and second element contacts of the first and second microelectronic elements, respectively, each of the first and second conductive vias having a third dimension in a third direction and a fourth dimension in a fourth direction, the fourth direction being transverse to the third direction and the first direction, the fourth dimension being greater than the third dimension.
