  • Patent number: 11927604
    Abstract: A wafer probe test system having a probe card with a probe head, a rotary magnet, a magnetic sensor positioned to sense the magnetic field of the rotary magnet and a controller coupled to the probe card, where the probe head has probe needles to engage features of test sites of a wafer in a wafer plane of orthogonal first and second directions, and the rotary magnet is rotatable around an axis of a third direction to provide a magnetic field to the wafer, in which the controller includes a model of magnetic flux density in the first, second and third directions at the respective test sites of the wafer as a function of a rotational angle of the rotary magnet, a probe needle height along the third direction and a measured magnetic flux density of the magnetic sensor.

  • Patent number: 11545270
    Abstract: A dossier change control management system periodically ingests data regarding a regulated product from multiple data stores. The dossier change control management system updates dossier data describing a dossier history for the regulated product using the received data. The dossier includes multiple documents in a standardized format and is updated based on a data mapping indicating correspondence between fields of the documents and portions of the received data. An out-of-expectation scenario for the dossier is identified based on regulatory requirements and an alert generated. A report with information about the out-of-expectation scenario is provided for display at a client device based on the alert.

  • Patent number: 11072867
    Abstract: Described herein are systems and methods for performing a surface mechanical attrition treatment (SMAT) to the surface of a variety of materials including thin films, nanomaterials, and other delicate and brittle materials. In an aspect, a surface of a material is modified to a modified surface and from an original state to a modified state, wherein the modified state comprises a physical modification, a chemical modification, or a biological modification. In another aspect, a surface mechanical attrition treatment (SMAT) is applied to the modified surface of the material for a defined duration of time, wherein a condition associated with the SMAT is adjusted based on a structural composition of the material. In yet another aspect, a defined strain is imposed on the structural composition of the material based on the SMAT.
