Abstract: Methods and apparatuses for assembly of a non-planar device based on curved chips are described. Slots may be created as longitudinal openings in the chips to reduce bending stresses to increase allowable degrees of deformation of the chips. The chips may be deformed to a desired deformation within the allowable degrees of deformation via the slots. Holding constraints may be provided on at least a portion of the chips to allow the chips to remain curved according the desired deformation.

Abstract: Fabrication methods for a flexible device for retina prosthesis are described. Layered structures including an array of pixel units may be formed over a substrate. Each pixel unit may comprise a processing circuitry, a micro electrode and a photo sensor. A first set of biocompatible layers may be formed over the layered structures. The substrate may be thinned down to a controlled thickness of the substrate to allow bending of the substrate to the curvature of a retina. A second set of biocompatible layers may be formed over the thinned substrate. The second set of biocompatible layers may be in contact with the first set of biocompatible layers to form a biocompatible seal wrapping around the device to allow long-term contact of the device with retina tissues. Micro electrodes of the pixel units may be exposed through the openings of these biocompatible layers.

Abstract: An implant apparatus comprising a plurality of photo sensors, a plurality of micro electrodes and circuitry coupled to the photo sensors and the micro electrodes are described. The photo sensors may receive incoming light. The circuit may drive the micro electrodes to stimulate neuron cells for enabling perception of a vision of the light captured by the photo sensors. The apparatus may be implemented in a flexible material to conform to a shape of a human eyeball to allow the micro electrodes aligned with the neuron cells for the stimulation.

Abstract: A rotary microactuator includes a stationary electrode formed on a substrate, a movable electrode in proximity to the stationary electrode, a flexure mechanically connecting the stationary electrode to the movable electrode, and a plurality of limiters anchored to the substrate. Each limiter has an in-plane limiter portion and an out-of-plane limiter portion. The in-plane limiter portion limits movement of the movable electrode to a predetermined in-plane distance in a direction parallel to a surface of the substrate. The out-of-plane limiter portion limits movement of the movement of the movable electrode to a predetermined out-of-plane distance.

Abstract: A non-planner integrated circuit device comprising a flexible structure and at least one fixture structure bonded to the flexible structure is described. The flexible structure may be curved in a desired deformation. A plurality of contact areas may be included in the flexible structure. Circuitry may be embedded within the flexible structure to perform processing operations. In one embodiment, the fixture structure may be bonded with the fixture structure via the contact areas to provide holding constraints allowing the flexible structure to remain curved. The bonding pads can also be used to connect communications in electrical signals.
