  • Patent number: 11585871
    Abstract: A system for and methods of semiconductor testing and characterization are disclosed. The system includes a parallel dipole line (PDL) system for applying a magnetic field to a sample in a measurement chamber and electrical equipment for testing the sample. The testing includes applying a first light exposure to the sample with the PDL system set to zero magnetic field and monitoring longitudinal resistance (Rxx) of the sample as intensity of the first light exposure varies. A second light exposure is applied with the PDL system set to maximum magnetic field, and transverse magnetoresistance (RB+) is monitored as light intensity varies. A third light exposure is applied with the PDL system set to minimum magnetic field, and transverse magnetoresistance (RB?) is monitored as light intensity varies. The characterization includes carrying out a photo-Hall analysis based on data from the testing.

  • Publication number: 20220277964
    Abstract: A method for planarizing a metal conductor layer embedded in a dielectric layer is provided. The method includes removing a portion of an overburden of the metal conductor layer that is formed over the dielectric layer with a first CMP slurry. The method also includes removing a remaining portion of the overburden of the metal conductor layer with a second CMP slurry to expose upper portions of the dielectric layer.

  • Patent number: 8751777
    Abstract: Methods and reconfigurable systems are provided for monitoring the health of a complex system. The reconfigurable system comprises a plurality of standardized executable application modules containing instructions to perform one of a plurality of different standardized functions. The system further comprises a plurality of computing nodes arranged in a hierarchical structure comprising one or more layers of computing nodes. Each computing node of the plurality runs a host application and a workflow service module, each computing node thereby being configured by a configuration file that directs the execution of any of the standardized executable application modules in a cooperative fashion by the host application via the workflow service module.
