A microelectronic element such as a chip or microelectronic wiring substrate is provided which includes a plurality of conductive interconnects for improved resistance to thermal stress. At least some of the conductive interconnects include a metallic plate, a metallic connecting line and an upper metallic via. The metallic connecting line has an upper surface at least substantially level with an upper surface of the metallic plate, an inner end connected to the metallic plate at one of the peripheral edges, and an outer end horizontally displaced from the one peripheral edge. The metallic connecting line has a width much smaller than the width of the one peripheral edge of the metallic plate and has length greater than the width of the one peripheral edge. The upper metallic via has a bottom end in contact with the metallic connecting line at a location that is horizontally displaced from the one peripheral edge by at least about 3 microns (μm).

Novel structures and methods for evaluating lines in semiconductor integrated circuits. A first plurality of lines are formed on a wafer each of which includes multiple line sections. All the line sections are of the same length. The electrical resistances of the line sections are measured. Then, a first line geometry adjustment is determined based on the electrical resistances of all the sections. The first line geometry adjustment represents an effective reduction of cross-section size of the lines due to grain boundary electrical resistance. A second plurality of lines of same length and thickness can be formed on the same wafer. Then, second and third line geometry adjustments are determined based on the electrical resistances of these lines measured at different temperatures. The second and third line geometry adjustments represent an effective reduction of cross-section size of the lines due to grain boundary electrical resistance and line surface roughness.

A structure and a method for operating the same. The method comprises providing a resistive/reflective region on a substrate, wherein the resistive/reflective region comprises a material having a characteristic of changing the material's reflectance due to the material absorbing heat; sending an electric current through the resistive/reflective region so as to cause a reflectance change in the resistive/reflective region from a first reflectance value to a second reflectance value different from the first reflectance value; and optically reading the reflectance change in the resistive/reflective region.

Systems and methods for applying both profile and user customizations to an application user interface are provided. Profile customizations, created for a specialized use or field, are adapted to an application user interface, which has command-menu-toolbar contributions from various add-in modules. The user has access to the customizations through a user interface. Then, as a user is customizing the application, through commands, toolbars, and menus, the user customizations are tagged. A priority and group is assigned to each customization to allow for relative positioning of each customization. The difference between the user's final desired state and a reset state is computed. This difference computation is used to track the changes made to the application and to assist in resets of the customizations.

An electronic structure having wiring, and an associated method of designing the structure, for limiting a temperature gradient in the wiring. The electronic structure includes a substrate having a layer that includes a first and second wire which do not physically touch each other. The first and second wires are adapted to be at an elevated temperature due to Joule heating in relation to electrical current density in the first and second wires. The first wire is electrically and thermally coupled to the second wire by an electrically and thermally conductive structure that exists outside of the layer. The width of the second wire is tailored so as to limit a temperature gradient in the first wire to be below a threshold value that is predetermined to be sufficiently small so as to substantially mitigate adverse effects of electromigration in the first wire.

Systems and methods for allowing challenge messages to be sent directly to a recipient's inbox where normally the challenge message would be sent to a pending folder or deleted. Challenge messages sent between federated messaging services contain a federated token which can be identified, authenticated and validated to determine whether the challenge message should be sent to a recipient's inbox. The federated token can include an authentication portion and a validation portion. Authentication methods for the authentication portion can include, for example, checksums, salts, hashes and digital signatures. Once a federated token is authenticated by decrypting the authentication portion according to one or more of these authentication methods, the federated token is validated by determining the defined use-base and determining whether the receipt of the federated token satisfies the defined use.

A thermo-mechanical cleavable structure is provided and may be used as a programmable fuse for integrated circuits. As applied to a programmable fuse, the thermo-mechanical cleavable structure includes an electrically conductive cleavable layer adjacent to a thermo-mechanical stressor. As electricity is passed through the cleavable layer, the cleavable layer and the thermo-mechanical stressor are heated and gas evolves from the thermo-mechanical stressor. The gas locally insulates the thermo-mechanical stressor, causing local melting adjacent to the bubbles in the thermo-mechanical stressor and the cleavable structure forming cleaving sites. The melting also interrupts the current flow through the cleavable structure so the cleavable structure cools and contracts. The thermo-mechanical stressor also contracts due to a phase change caused by the evolution of gas therefrom. As the thermo-mechanical cleavable structure cools, the cleaving sites expand causing gaps to be permanently formed therein.
