Abstract:
1. An non-planar integrated circuit device, the device comprising: a flexible structure curved in a desired deformation from planar shapes, the flexible structure having a front surface, a back surface and a perimeter, the flexible structure including one or more layers of semiconductor material, the layers including a circuitry to perform processing operations, each layer being curved in the desired deformation; cutout channel openings arranged around a center portion of the flexible structure, wherein each cutout channel opening cuts through a thickness between the front surface and the back surface, the cut through of the thickness extending throughout the cutout channel opening longitudinally from the perimeter towards the center portion of the flexible structure, wherein the desired deformation from planar shapes causes displacement stresses in the flexible structure, the cutout channel openings to reduce the displacement stresses; a plurality of bonding structures extending externally over the layers of semiconductor material; and at least one fixture structure bonded to the flexible structure via the bonding structures to provide holding constraints allowing the flexible structure to remain curved.
