Abstract: Semiconductor-on-insulator (SOI) structures, including large area SOI structures, are provided which have one or more regions composed of a layer (15) of a substantially single-crystal semiconductor (e.g., doped silicon) attached to a support substrate (20) composed of an oxide glass or an oxide glass-ceramic. The oxide glass or oxide glass-ceramic is preferably transparent and preferably has a strain point of less than 1000° C., a resistivity at 250° C. that is less than or equal to 1016 ?-cm, and contains positive ions (e.g., alkali or alkaline-earth ions) which can move within the glass or glass-ceramic in response to an electric field at elevated temperatures (e.g., 300-1000° C.). The bond strength between the semiconductor layer (15) and the support substrate (20) is preferably at least 8 joules/meter2. The semiconductor layer (15) can include a hybrid region (16) in which the semiconductor material has reacted with oxygen ions originating from the glass or glass-ceramic.

Abstract: An OLED structure includes a substantially flexible substrate, and at least one barrier layer disposed between the substrate and the OLED structure. The barrier layer substantially prevents contaminants from permeating a layer of organic material or the OLED structure. The barrier layer includes a glass layer that has certain components added or removed to improve its flexibility. The OLED structure may also include a substantially flexible substrate and at least one barrier layer disposed between the substrate and the OLED structure. The barrier layer includes a strain relief material. The strain relief material advantageously has at least one axis of orientation. Photonic or electronic components, or both could be substituted for the OLED.

Abstract: Methods and apparatus provide for: a silicon on insulator structure, comprising: a glass substrate; a layer of semiconductor material; and a deposited barrier layer of between about 60 nm to about 600 nm disposed between the glass substrate and the semiconductor material, where the glass substrate and semiconductor material are bonded together via electrolysis.

Abstract: A method of forming a semiconductor on glass structure includes: establishing an exfoliation layer on a semiconductor wafer; contacting the exfoliation layer of the semiconductor wafer to a glass substrate; applying pressure, temperature and voltage to the semiconductor wafer and the glass substrate, without a vacuum atmosphere, such that a bond is established therebetween via electrolysis; and applying stress such that the exfoliation layer separates from the semiconductor wafer and remains bonded to the glass substrate.

The method also includes providing nucleation material and forming the crystalline layer over the nucleation material. The crystalline material disposed over the substrate may be monocrystalline or polycrystalline.
