Slots (e.g., 301, 303, 405, 603, 605) may be created as longitudinal openings in the chips (e.g., 305, 403, 601, 607) to reduce bending stresses to increase allowable degrees of deformation of the chips (e.g., 305, 403, 601, 607). The chips (e.g., 305, 403, 601, 607) may be deformed to a desired deformation within the allowable degrees of deformation via the slots (e.g., 301, 303, 405, 603, 605). Holding constraints may be provided on at least a portion of the chips to allow the chips to remain curved according the desired deformation. A non-planar integrated circuit device (200B) comprising a flexible structure (213) and at least one fixture structure bonded to the flexible structure is also described. The flexible structure (213) may be curved in a desired deformation. A plurality of contact areas may be included in the flexible structure (213). Circuitry may be embedded within the flexible structure (213) to perform processing operations.
