Abstract: A memory cell provides point defect trap sites in an insulator for storing data charges. Single electrons are stored on respective point defect trap sites and a resulting parameter, such as transistor drain current, is detected. By adjusting the density of the point defect trap sites, more uniform step changes in drain current are obtained as single electrons are stored on or removed from respective trap sites. By also adjusting the trapping energy of the point defect trap sites, the memory cell provides either volatile data storage, similar to a dynamic random access memory (DRAM), or nonvolatile data storage, similar to an electrically erasable and programmable read only memory (EEPROM). The memory cell is used for storing binary or multi-state data.

A functional circuit is formed on the first surface of the semiconductor wafer. Further, a metallization layer is formed outwardly from the first surface of the semiconductor wafer. The integrated circuit also includes at least one high aspect ratio via that extends through the layer of semiconductor material. This via provides a connection between a lead and the functional circuit.

Abstract: An integrated circuit with a number of optical fibers that are formed in high aspect ratio holes. The high aspect ratio holes extend through a semiconductor wafer. The optical fibers include a cladding layer and a core formed in the high aspect ratio hole. These optical fibers are used to transmit signals between functional circuits on the semiconductor wafer and functional circuits on the back of the wafer or beneath the wafer.

Abstract: Methods of forming integrated circuitry lines such as coaxial integrated circuitry interconnect lines, and related integrated circuitry are described. An inner conductive coaxial line component is formed which extends through a substrate. An outer conductive coaxial line component and coaxial dielectric material are formed, with the coaxial dielectric material being formed operably proximate and between the inner and outer conductive coaxial line components. In a preferred implementation, the substrate includes front and back surfaces, and a hole is formed which extends through the substrate and between the front and back surfaces. In one implementation, the outer conductive coaxial line component constitutes doped semiconductive material. In another implementation, such constitutes a layer of metal-comprising material. A layer of dielectric material is formed over and radially inwardly of the outer line component. Conductive material is then formed over and radially inwardly of the dielectric material layer.

The optical waveguides include a highly reflective material that is deposited so as to line an inner surface of the high aspect ratio holes which may be filled with air or a material with an index of refraction that is greater than 1. These metal confined waveguides are used to transmit signals between functional circuits on the semiconductor wafer and functional circuits on the back of the wafer or beneath the wafer.

A polycrystalline semiconductor plate is formed outwardly from the insulator layer in the trench.

Abstract: A method and structure for textured surfaces in non volatile floating gate tunneling oxide (FLOTOX) devices, e.g. FLOTOX transistors, are provided. The present invention capitalizes on using "self-structured masks" and a controlled etch to form nanometer scale microtip arrays to form the textured surfaces. The present invention further employs atomic layer epitaxy (ALE) to create a very conformal tunnel oxide layer which complements the nanometer scale microtip arrays. The resulting structure provides a higher tunneling current than currently exists in FLOTOX technology. The improved tunneling currents at low voltages can make these FLOTOX devices suitable for replacing DRAMS.

Abstract: A method and structure for high capacitance memory cells is provided. The method includes forming a trench capacitor in a semiconductor substrate. A self-structured mask is formed on the interior surface of the trench. The interior surface of the trench is etched to form an array of silicon pillars. The self-structured mask is removed. Then an insulator layer is formed on the array of silicon pillars. A polycrystalline semiconductor plate extends outwardly from the insulator layer in the trench.

Abstract: A CMOS-compatible FET has a reduced electron affinity polycrystalline or microcrystalline silicon oxycarbide (SiOC) gate that is electrically isolated (floating) or interconnected. The SiOC material composition is selected to establish a desired barrier energy between the SiOC gate and a gate insulator. In a memory application, such as a flash EEPROM, the SiOC composition is selected to establish a lower barrier energy to reduce write and erase voltages and times or accommodate the particular data charge retention time needed for the particular application. In a light detector or imaging application, the SiOC composition is selected to provide sensitivity to the desired wavelength of light. Unlike conventional photodetectors, light is absorbed in the floating gate, thereby ejecting previously stored electrons therefrom. Also unlike conventional photodetectors, the light detector according to the present invention is actually more sensitive to lower energy photons as the semiconductor bandgap is increased.

Abstract: Operating margins for major-minor magnetic bubble memories are improved by use of protective rails between minor loops to prevent loss of information due to stripout. The rails, as are the propagation paths, are defined by unimplanted regions in an otherwise ion-implanted layer. In another embodiment, unimplanted rectangular islands are used rather than rails.
