    摘要： BEOL memory cells are described that include one or more sidewall protection layers on the memory device (including, for example, an MTJ element) deposited prior to interconnect via etching to prevent the formation of electrical shorts between layers. One embodiment uses a single layer sidewall protection sleeve that is deposited after the memory device has been patterned. The layer material is vertically etched down to expose the upper surface of the top electrode while leaving a residual layer of protective material surrounding the rest of the memory device. The material for the protection layer is selected to resist the etchant used to remove the first dielectric material from the via in the subsequent interconnect process. A second embodiment uses dual-layer sidewall protection in which the first layer covers the memory element is preferably an oxygen-free dielectric and the second layer protects the first layer during via etching.

    摘要： High-frequency resonance method is used to measure magnetic parameters of magnetic thin film stacks that show magnetoresistance including MTJs and giant magnetoresistance spin valves. The thin film sample can be unpatterned. Probe tips are electrically connected to the surface of the film (or alternatively one probe tip can be punched into the thin film stack) and voltage measurements are taken while injecting high frequency oscillating current between them to cause a change in electrical resistance when one of the layers in the magnetic film stack changes direction. A measured resonance curve can be determined from voltages at different current frequencies. The damping, related to the width of the resonance curve peak, is determined through curve fitting. In embodiments of the invention a variable magnetic field is also applied to vary the resonance frequency and extract the magnetic anisotropy and/or magnetic saturation of the magnetic layers.

    摘要： A corrosion-resistant apparatus may contain an electronic component having a metal covered by a conformal coating. The conformal coating may contain polymer chains with unsaturated groups capable of scavenging a corrosive agent. The conformal coating may contain an accelerator or activator so that the unsaturated groups more readily scavenge the corrosive agent. In an embodiment, the conformal coating is a silicone coating with unsaturated pendant groups which scavenge a sulfur containing agent.

    摘要： A method comprising injection molding a plastic part from a polymer formulation comprising an injection moldable thermoplastic and a fluorescent compound, wherein the fluorescent compound has a decomposition temperature that establishes a maximum processing temperature for the polymer formulation. The fluorescent compound will thermally decompose to generate gaseous products causing visible bubble formation in the surface of the plastic part in response to exposure to a processing temperature that exceeds the decomposition temperature of the fluorescent compound. If the plastic part was processed without exposure to a processing temperature that exceeds the decomposition temperature of the fluorescent compound, then any fluorescent compound within the plastic part will cause the plastic part to fluoresce in response to exposure to black light. A suitable fluorescent compound may be, for example, selected from oxalates, carbamic acids, carbonic acids, diazocarbonyl compounds, and combinations thereof. A preferred fluorescent compound is bis(2,4,6-trichlorophenyl)oxalate.

    摘要： The present invention discloses a side-light type light guide plate assembly and a backlight module, which has a light guide plate and at least one reflector sheet. The light guide plate has a lower surface, a light output surface opposite to the lower surface, and at least one light input side surface connected between the lower surface and the light output surface. The reflector sheet is correspondingly disposed on at least one side surface of the light guide plate except for the light input side surface, while a medium layer is defined between the reflector sheet and the light guide plate. The refraction index of the medium layer is smaller than or equal to 1.12. By providing the air layer and the reflector sheet, light beam emitting out of a side of the light guide plate and going back to the light guide plate can meet conditions of total reflection, so as to prevent from generating a light leakage phenomenon at edges of the light guide plate.

    摘要： Fabrication methods for MRAM are described wherein any re-deposited metal on the sidewalls of the memory element pillars is cleaned before the interconnection process is begun. In embodiments the pillars are first fabricated, then a dielectric material is deposited on the pillars over the re-deposited metal on the sidewalls. The dielectric material substantially covers any exposed metal and therefore reduces sources of re-deposition during subsequent etching. Etching is then performed to remove the dielectric material from the top electrode and the sidewalls of the pillars down to at least the bottom edge of the barrier. The result is that the previously re-deposited metal that could result in an electrical short on the sidewalls of the barrier is removed. Various embodiments of the invention include ways of enhancing or optimizing the process. The bitline interconnection process proceeds after the sidewalls have been etched clean as described.
