摘要： A method and system are provided for determining a guard band voltage differential for testing a microprocessor. The guard band voltage differential approximates microprocessor circuit propagation delay degradation expected to occur over the life of the microprocessor. The system and method are performed by first partitioning a microprocessor into a plurality of cones of n circuit level models. Timing simulation data and degradation data are created to represent, respectively, the timing operation for each of the circuit level model circuit paths, and the hot-electron effects on propagation delay degradation for each of the circuit level models. Propagation delay is identified using this data for each of the circuit paths for the circuit level models at times corresponding to the beginning-of-life and end-of-life of the microprocessor. Propagation delay degradation is calculated as the difference between the propagation delay at these times. A range of applied power supply voltages necessary to successfully perform a functional test of the microprocessor over a corresponding range of microprocessor cycle times is experimentally determined. Based on the calculated propagation delay degradation and on the range of applied power supply voltages, a guard band voltage differential for testing the microprocessor is determined.

摘要： A method of assessing the tolerance of a microprocessor to propagation time degradation caused by electromigration effects and hot electron effects is provided. Reference values for interconnection resistance (IR) degradation and drain current (DC) degradation are compute, at nominal fabrication process and microprocessor lifetime application conditions. These results may be tabulated for a plurality of output driver load capacitances. Test IR degradation and test DC degradation values are calculated by scaling the reference IR and DC degradation values, respectively, for actual test conditions. The circuit propagation time and the propagation delay degradation caused by both electromigration and hot electron effects are calculated at process and lifetime environmental conditions. A timing equation is evaluated using distinctly identified components of the propagation delay degradation caused by electromigration and hot electron effects, to assess the toleration of the microprocessor to electromigration and hot electron induced propagation delay degradation.

摘要： A method and structure for fabricating a laser fuse and a method for programming the laser fuse. The laser fuse includes a dielectric layer having two vias filled with a first self-passivated electrically conducting material. A fuse link is on top of the dielectric layer. The fuse link electrically connects the two vias and includes a second material having a characteristic of changing its electrical resistance after being exposed to a laser beam. Two mesas are over the fuse link and directly over the two vias. The two mesas each include a third self-passivated electrically conducting material. The laser fuse is programmed by directing a laser beam to the fuse link. The laser beam is controlled such that, in response to the impact of the laser beam upon the fuse link, the electrical resistance of the fuse link changes but the fuse link is not blown off. Such electrical resistance change is sensed and converted to digital signal.

摘要： An array of through substrate vias (TSVs) is formed through a semiconductor substrate and a contact-via-level dielectric layer thereupon. A metal-wire-level dielectric layer and a line-level metal wiring structure embedded therein are formed directly on the contact-via-level dielectric layer. The line-level metal wiring structure includes cheesing holes that are filled with isolated portions of the metal-wire-level dielectric layer. In one embodiment, the entirety of the cheesing holes is located outside the area of the array of the TSVs to maximize the contact area between the TSVs and the line-level metal wiring structure. In another embodiment, a set of cheesing holes overlying an entirety of seams in the array of TSVs is formed to prevent trapping of any plating solution in the seams of the TSVs during plating to prevent corrosion of the TSVs at the seams.
