    Abstract: Provided are methods and composition for forming an isolation structure on an integrated circuit substrate. First, a trench is etched in the integrated circuit substrate. A lower dielectric layer is then formed in the trench such that the lower dielectric layer at least partially fills the trench. An upper dielectric layer is then formed over the lower dielectric layer to create an isolation structure, the upper dielectric layer and the lower dielectric layer together having an effective dielectric constant that is less than that of silicon dioxide, thereby enabling capacitance associated with the isolation structure to be reduced.

    Abstract: The present invention relates to electrically active devices (e.g., capacitors, transistors, diodes, floating gate memory cells, etc.) having dielectric, conductor, and/or semiconductor layers with smooth and/or dome-shaped profiles and methods of forming such devices by depositing or printing (e.g., inkjet printing) an ink composition that includes a semiconductor, metal, or dielectric precursor. The smooth and/or dome-shaped cross-sectional profile allows for smooth topological transitions without sharp steps, preventing feature discontinuities during deposition and allowing for more complete step coverage of subsequently deposited structures. The inventive profile allows for both the uniform growth of oxide layers by thermal oxidation, and substantially uniform etching rates of the structures. Such oxide layers may have a uniform thickness and provide substantially complete coverage of the underlying electrically active feature. Uniform etching allows for an efficient method of reducing a critical dimension of an electrically active structure by simple isotropic etch.

    Abstract: A memory cell having a transistor and a capacitor formed in a silicon substrate. The capacitor is formed with a lower electrically conductive plate etched in a projected surface area of the silicon substrate. The lower electrically conductive plate has at least one cross section in the shape of a vee, where the sides of the vee are disposed at an angle of about fifty-five degrees from a top surface of the silicon substrate. The surface area of the lower electrically conductive plate is about seventy-three percent larger than the projected surface area of the silicon substrate in which the lower electrically conductive plate is etched. A capacitor dielectric layer is formed of a first deposited dielectric layer, which is disposed adjacent the lower electrically conductive plate. A top electrically conductive plate is disposed adjacent the capacitor dielectric layer and opposite the lower electrically conductive plate. A transistor is formed having source and drain regions separated by a channel region, and a gate dielectric layer formed of the first deposited dielectric layer.

    Abstract: Silicon nitride gate insulators for digital transistors and silicon dioxide gate insulators for analog transistors of a hybrid integrated circuit (IC) are formed in a single integrated fabrication process. A first area of a silicon substrate of the IC is exposed while a second area is initially covered by a silicon dioxide layer. A layer of silicon nitride is formed on the exposed first area while the initial silicon dioxide layer inhibits the formation of silicon nitride on the second area. Thereafter the initial silicon dioxide layer is removed from the second area to allow a new silicon dioxide layer to be formed there from the exposed silicon substrate. The silicon dioxide layer shields against the adverse influences from silicon nitride formation and permits the initial silicon dioxide layer to be removed by etching. The silicon nitride layer shields against the adverse influences of oxidizing new silicon dioxide layer. A slight, beneficial silicon dioxide interface is created between the silicon nitride and the silicon substrate as a result of oxidizing the new layer of silicon dioxide.

The battery includes first and second metal substrates, a first solid-state and/or thin-film battery cell on the first metal substrate, a second solid-state and/or thin-film battery cell on the second metal substrate, and a hermetic seal in a peripheral region of the first and second metal substrates. The first and second battery cells are between the first and second metal substrates, and face each other. The method includes respectively forming first and second solid-state and/or thin-film battery cells on first and second metal substrates, placing the second battery cell on the first battery cell so that the first and second battery cells are between the first and second metal substrates, and hermetically sealing the first and second battery cells in a peripheral region of the first and second metal substrates.
