    摘要: An MRI RF transmit system uses a plurality of RF transmit coils, each being driven with separately controllable RF magnitude and phase. The magnitude and phase of each coil drive are separately and independently controlled so that the RF transmit coils act as if they are decoupled from each other. The controlled magnitude and phase values may be based on empirically derived information relating to self and mutual coupling of RF transmit coils.

    摘要: A process is provided for etching a mask layer and removal of residue from a structure having an area sheltered from directional etching. The structure has a shape that forms a silhouette area obstructed from being etched by anisotropic bombardment originating from a first direction, and a mask formed over the mask layer over the structure; A first etch process removes at least a part of the mask layer and retains at least a part of mask layer in the sheltered area. A second etch process removes at least a part of the mask layer in the sheltered area by hydrogen based microwave plasma etching.

    摘要: A memory array having memory cells comprising a diode and an antifuse can be made smaller and programmed at lower voltage by using an antifuse material having a higher dielectric constant and a higher acceleration factor than those of silicon dioxide, and by using a diode having a lower band gap than that of silicon. Such memory arrays can be made to have long operating lifetimes by using the high acceleration factor and lower band gap materials. Antifuse materials having dielectric constants between 5 and 27, for example, hafnium silicon oxynitride or hafnium silicon oxide, are particularly effective. Diode materials with band gaps lower than that of silicon, such as germanium or a silicon-germanium alloy, are particularly effective.

    摘要: A two terminal nonvolatile memory cell includes a first electrode, a second electrode, a charge storage medium, and a resistive element. The charge storage medium and the resistive element are connected in parallel between the first and the second electrodes. A presence or absence of charge being stored in the charge storage medium affects a resistivity of the resistive element.
