  • Patent number: 10211155
    Abstract: Methods are provided for fabricating metallic interconnect structures having reduced electrical resistivity that is obtained by applying mechanical strain to the metallic interconnect structures, as well as semiconductor structures having metallic interconnect structures formed with permanent mechanical strain to provide reduced electrical resistivity. For example, a method includes forming a metallic interconnect structure in an interlevel dielectric (ILD) layer of a back-end-of-line (BEOL) structure of a semiconductor structure, and forming a stress layer in contact with the metallic interconnect structure. A thermal anneal process is performed to cause the stress layer to expand and apply compressive strain to the metallic interconnect structure and permanently deform at least a portion of the metallic interconnect structure into a stress memorized state of compressive strain.

  • Patent number: 10211151
    Abstract: A method of forming a self-aligned pattern of vias in a semiconductor device comprises etching a pattern of lines that contain notches that are narrower than other parts of the line. Thereafter, vias are created where the notches are located. The locations of the vias are such that the effect of blown-out areas is minimized. Thereafter, the lines are etched and the vias and line areas are filled. The layers are planarized such that the metal fill is level with a surrounding ultra-low-k dielectric. Additional metal layers, lines, and vias can be created. Other embodiments are also described herein.

    Abstract: A method for forming a semiconductor structure using first and second conductive materials, and having first and second trenches with first and second critical dimensions. The second conductive material exhibits a lower resistivity than the first conductive material at a film thickness corresponding to the second critical dimension and the second conductive material exhibits a higher resistivity than the first conductive material at a film thickness corresponding to the first critical dimension. An initial semiconductor structure has the first trench having the first critical dimension and the second trench having the second critical dimension. The second critical dimension is larger than the first critical dimension. A first conductive structure made from one of the first and second conductive materials is formed in the first trench. A second conductive structure made from another of the first and second conductive materials is formed in the second trench.

  • Patent number: 10195901
    Abstract: Techniques are provided for alerting drivers of hazardous driving conditions using the sensing capabilities of wearable mobile technology. In one aspect, a method for alerting drivers of hazardous driving conditions includes the steps of: collecting real-time data from a driver of a vehicle, wherein the data is collected via a mobile device worn by the driver; determining whether the real-time data indicates that a hazardous driving condition exists; providing feedback to the driver if the real-time data indicates that a hazardous driving condition exists, and continuing to collect data from the driver in real-time if the real-time data indicates that a hazardous driving condition does not exist. The real-time data may also be collected and used to learn characteristics of the driver. These characteristics can be compared with the data being collected to help determine, in real-time, whether the driving behavior is normal and whether a hazardous driving condition exists.

  • Patent number: 10192829
    Abstract: Low-temperature techniques for doping of Cu interconnects based on interfacially-assisted thermal diffusion are provided. In one aspect, a method of forming doped copper interconnects includes the steps of: patterning at least one trench in a dielectric material; forming a barrier layer lining the trench; forming a metal liner on the barrier layer; depositing a seed layer on the metal liner; plating a Cu fill into the trench to form Cu interconnects; removing a portion of a Cu overburden to access an interface between the metal liner and the Cu fill; depositing a dopant layer; and diffusing a dopant(s) from the dopant layer along the interface to form a Cu interconnect doping layer between the metal liner and the Cu fill. Alternatively, the overburden and the barrier layer/metal liner can be completely removed, and the dopant layer deposited selectively on the Cu fill. An interconnect structure is also provided.

  • Patent number: 10170411
    Abstract: A method for via alignment includes forming first airgaps between interconnect structures and depositing a pinch off layer to close off openings to the first airgaps. A protection layer is formed in divots in the pinch off layer. The protection layer and the pinch off layer are planarized to form a surface where the protection layer remains in the divots. An interlevel dielectric layer (ILD) is deposited on the surface. The ILD and the pinch off layer are etched using the protection layer as an etch stop to align a via and expose the interconnect structure through the via.
