  • Publication number: 20260009845
    Abstract: Systems, devices, and methods for performing a non-contact electrical measurement (NCEM) on a NCEM-enabled cell included in a NCEM-enabled cell vehicle may be configured to perform NCEMs while the NCEM-enabled cell vehicle is moving. The movement may be due to vibrations in the system and/or movement of a movable stage on which the NCEM-enabled cell vehicle is positioned. Position information for an electron beam column producing the electron beam performing the NCEMs and/or for the moving stage may be used to align the electron beam with targets on the NCEM-enabled cell vehicle while it is moving.

  • Patent number: 12416663
    Abstract: A novel system for in-product Bias Temperature Instability (BTI) characterization that allows for characterization of transistor degradation rates is disclosed; it is self-testing and can be embedded in real products without impacting the host functionality. The test data collected during product chip testing (at Electrical Wafer Sort) can be used for identification of abnormal material and for material disposition, or to predict the chip aging rate and premature failure risk due to BTI degradation. The system can also collect the data from the real time device aging in the field, during the host chip operational lifetime. The system is equipped with local programmable power supply generation and self-test capabilities to allow concurrent operations with the host application. The Devices Under Test (DUTs) consist of standard cell-based Ring Oscillators (ROs) which have the unique capability of decoupling the BTI effects on N-type and P-type MOSFET transistors.

  • Publication number: 20250043098
    Abstract: A PET recycling (the reprocessing of polyethylene terephthalate wastes) has already been practised for many decades in a variety of different ways, since PET is available in large quantities. Environmental protection and sustainability in resource utilization, however, call for ever higher recycling rates in the decades to come. If the concept of a circular economy is to be achieved, this rate must ultimately amount, sooner or later, to 100%.

  • Patent number: 11814486
    Abstract: Apparatuses and processes may be utilized for mixing used polyester into a polyester melt. In some processes an intermediate product stream is branched off from an intermediate stage in a virgin polyester production process. The intermediate product stream is then mixed with recycled polyester flakes in a dynamic mixer, where not more than 60% of a melting energy required to melt all the recycled polyester flakes is generated and/or supplied in the dynamic mixer. The mixture produced in this way is fed into a subsequent stage downstream of the intermediate stage and converted up to the desired degree of polycondensation. In this way, it is possible to physically reutilize used polyester or polyester waste.
