  • Patent number: 7606677
    Abstract: A metrology recipe includes dynamic instructions that allow a metrology tool to perform a secondary metrology operation on a test wafer when previous measurement data indicates a process issue with that test wafer. The metrology recipe can instruct the metrology tool to perform an efficient default metrology operation on all test wafers, and perform a more in-depth secondary metrology operation on only those wafers that warrant additional scrutiny. In this manner, critical metrology data can be captured with a minimum of effect on metrology throughput. The metrology data used to determine whether or not the secondary metrology operation is to be performed can be generated from default metrology operations within the same tool, or can be generated by measurements taken by a completely different tool. Such “external” metrology data can be received via a communications network, either directly or from a server on the network for processing the metrology data.

  • Patent number: 7603253
    Abstract: A method for updating the return on investment (ROI) templates used by business consultants. The present invention comprises a Template Evaluation Program (TEP) and a Template Analysis Program (TAP). The TEP compares the default template to the templates modified by the consultants for the customer's ROI analysis and assigns an effectiveness factor to the modified templates. The TAP develops a data list from the default templates and the effectiveness factors and plots the data on a histogram. The TAP performs a statistical analysis for each parameter and updates the default template parameter values if the data fits a normal distribution curve. If the data forms more than one peak on the histogram, then the TAP uses one peak to update the default template and uses the second peak to create a new template. The new template's parameter value is derived from the data in the second peak.

  • Patent number: 7539584
    Abstract: A system and method for sizing semiconductor wafer defects combines contiguous light intensity values over a defect area of the wafer to provide a defect sizing metric. The light intensity values resulting from a light source applied to the wafer are summed and the summation is compared to known metric values related to known defect sizes. The result of the comparison provides an estimate for the defect size under consideration. The combination of the light intensity values produces defect sizing estimates in saturated and unsaturated ranges of operation for the wafer inspection equipment. Calculations applied to the combined light intensity values vary depending upon whether the light intensity component is from a saturated or an unsaturated measurement. The defect sizing metric can be applied continuously in saturated and unsaturated ranges of operation to avoid additional processing steps, such as recalibration of the inspection equipment.

  • Patent number: 7519498
    Abstract: The present invention provides a method, an apparatus, and a computer program product for measuring the temperature of a microprocessor through the use of ESD circuitry. The present invention uses diodes and an I/O pad within ESD circuits to determine the temperature at the location of the ESD circuitry. First, a current measuring device connects to a diode. A user or a computer program disables the protected component or circuitry, and subsequently applies a predetermined voltage to the I/O pad. This creates a reverse saturation current through the diode, which is measured by the current measuring device. From this current the user or a computer program determines the temperature of the microprocessor at the diode through the use of a graphical representation of diode reverse saturation current and corresponding temperature.

  • Patent number: 7512500
    Abstract: A method for initializing a chain of non-initialized data collectors is disclosed. The chain of non-initialized data collectors are coupled to a controller. In a first step communication between the controller and each data collector in the chain of non-initialized collectors is disabled, except for an active non-initialized data collector, The active non-initialized collector is coupled to the controller and any remaining non-initialized data collectors. Next, the active non-initialized data collector is initialized by assigning an identification number to the active non-initialized data collectors. The active non-initialized collector becomes an initialized data collector. Then, communication is restored between the initialized data collector and a next active non-initialized data collector in the chain of non-initialized data collectors. The method repeats until all non-initialized data collectors are initialized.
