Abstract: A method for forming a back-illuminated image sensor includes forming a higher doped crystalline layer on a crystalline substrate, growing a lower doped crystalline layer on the higher doped crystalline layer and forming a photodiode and component circuitry from the lower doped crystalline layer. Metallization structures are formed to make connections to and between components. The crystalline substrate is removed to expose the higher doped crystalline layer. An optical component structure is provided on an exposed surface of the higher doped crystalline layer to receive light therein such that the higher doped crystalline layer provides a passivation layer for the photodiode and the component circuitry.

Abstract: Semiconductor nanoparticles are deposited on a top surface of a first insulator layer of a substrate. A second insulator layer is deposited over the semiconductor nanoparticles and the first insulator layer. A semiconductor layer is then bonded to the second insulator layer to provide a semiconductor-on-insulator substrate, which includes a buried insulator layer including the first and second insulator layers and embedded semiconductor nanoparticles therein. Back gate electrodes are formed underneath the buried insulator layer, and shallow trench isolation structures are formed to isolate the back gate electrodes. Field effect transistors are formed in a memory device region and a logic device region employing same processing steps. The embedded nanoparticles can be employed as a charge storage element of non-volatile memory devices, in which charge carriers tunnel through the second insulator layer into or out of the semiconductor nanoparticles during writing and erasing.

Abstract: Fabrication methods are disclosed that facilitate the production of electronic structures that are both flexible and stretchable to conform to non-planar (e.g. curved) surfaces without suffering functional damage due to excessive strain. Electronic structures including CMOS devices are provided that can be stretched or squeezed within acceptable limits without failing or breaking. The methods disclosed herein further facilitate the production of flexible, stretchable electronic structures having multiple levels of intra-chip connectors. Such connectors are formed through deposition and photolithographic patterning (back end of the line processing) and can be released following transfer of the electronic structures to flexible substrates.

Abstract: High resolution active matrix structures are fabricated using techniques applicable to flexible substrates. A backplane layer including active semiconductor devices is formed using a semiconductor-on-insulator substrate. The substrate is thinned using a layer transfer technique or chemical/mechanical processing. Driver transistors are formed on the semiconductor layer of the substrate along with additional circuits that provide other functions such as computing or sensing. Contacts to passive devices such as organic light emitting diodes may be provided by heavily doped regions formed in the handle layer of the substrate and then isolated. A gate dielectric layer may be formed on the semiconductor layer, which functions as a channel layer, or the insulator layer of the substrate may be employed as a gate dielectric layer.
