    摘要: A micro-electro-mechanical systems (MEMS) pixel for display and touch position sensing includes a substrate and a capacitive element. The capacitive element includes one or more pixels having a first conductive platelet above the substrate, and a second conductive platelet above and spaced apart from the first conductive platelet, the two platelets forming the capacitive element. A connection to each platelet provides for applying a voltage, wherein the platelet separation changes according to the applied voltage. A transparent dielectric plate, spaced apart from and positioned opposite the substrate, covers the at least one pixel. A capacitance sensing circuit attached to the connection to each platelet of the pixel senses changes in capacitance not resulting from the applied voltage.

    摘要: A computer program product estimates performance of an interconnect structure of a semiconductor integrated circuit (IC). The program product includes code executing on a computer to calculate at least one electrical characteristic of the interconnect structure based on input data accounting for multiple layers of the interconnect structure. The electrical characteristics can be capacitance, resistance, and/or inductance. The capacitance may be based upon multiple components, including a fringe capacitance component, a terminal capacitance component, and a coupling capacitance component.

    摘要: By filling an air gap between tiers of a stacked IC device with a thermally conductive material, heat generated at one or more locations within one of the tiers can be laterally displaced. The lateral displacement of the heat can be along the full length of the tier and the thermal material can be electrically insulating. Through silicon-vias (TSVs) can be constructed at certain locations to assist in heat dissipation away from thermally troubled locations.

    摘要: A method for forming a magnetic tunnel junction (MTJ) for magnetic random access memory (MRAM) using two masks includes depositing over an interlevel dielectric layer containing an exposed first interconnect metallization, a first electrode, a fixed magnetization layer, a tunneling barrier layer, a free magnetization layer and a second electrode. An MTJ structure including the tunnel barrier layer, free layer and second electrode is defined above the first interconnect metallization by a first mask. A first passivation layer encapsulates the MTJ structure, leaving the second electrode exposed. A third electrode is deposited in contact with the second electrode. A second mask is used to pattern a larger structure including the third electrode, the first passivation layer, the fixed magnetization layer and the first electrode. A second dielectric passivation layer covers the etched plurality of layers, the first interlevel dielectric layer and the first interconnect metallization.

    摘要: Magnetic tunnel junctions (MTJs) and methods of forming same are disclosed. A pinned layer is disposed in the MTJ such that a free layer of the MTJ can couple to a drain of an access transistor when provided in a magnetic random access memory (MRAM) bitcell. This structure alters the write current flow direction to align the write current characteristics of the MTJ with write current supply capability of an MRAM bitcell employing the MTJ. As a result, more write current can be provided to switch the MTJ from a parallel (P) to anti-parallel (AP) state. An anti-ferromagnetic material (AFM) layer is provided on the pinned layer to fix pinned layer magnetization. To provide enough area for depositing the AFM layer to secure pinned layer magnetization, a pinned layer having a pinned layer surface area greater than a free layer surface area of the free layer is provided.
