  • Patent number: 8723321
    Abstract: The peeling stress between a Cu line and a capping layer thereon, after via patterning, is reduced by varying the shape of the via and positioning the via to increase the space between the via and the line edge, thereby increasing electromigration lifetime. Embodiments include varying the shape of the via, as by forming an oval or rectangular shape via, such that the ratio of the minor axis of the oval to the line with or the ratio of the width of the rectangle to the line width is less than about 0.7.

  • Patent number: 8501504
    Abstract: According to one exemplary embodiment, a non-destructive method for determining a breakdown voltage of a dielectric layer on a semiconductor substrate includes injecting a test current in increasing ramp steps into the dielectric layer. The method further includes measuring a test voltage across the dielectric layer at each increasing ramp step of the test current. The method further includes detecting a dropped test voltage in response to the increasing ramp steps of the test current. The ramp steps of the test current can be substantially logarithmically increased. The breakdown voltage of the dielectric layer can be designated to be substantially equal to the dropped test voltage.

  • Patent number: 8022716
    Abstract: A time-to-breakdown for a dielectric layer in a semiconductor device is determined based upon a sudden change in capacitance. An alternating voltage, greater in magnitude than an operating voltage of the device, is applied to the semiconductor device, capacitance is measured across the dielectric layer during the application of the voltage until a sudden change in capacitance occurs, thereby indicating a breakdown in the dielectric layer, and the breakdown time is scaled to the operating voltage.
