Abstract: A monolithic microelectronic array structure includes a microelectronic integrated circuit array having a first plurality of microelectronic integrated circuit elements each deposited on a front side of a substrate. The substrates are physically discontinuous so that each substrate comprises a substrate island which is physically separated from the other substrate islands. The monolithic microelectronic array structure optionally includes a first plurality of input/output elements with a respective input/output element associated with and directly connected to each of the microelectronic integrated circuit elements, and a second plurality of electrically conductive interconnects extending between the microelectronic integrated circuit elements of adjacent substrate islands. The monolithic microelectronic array structure may be planar, or it may be curved.
