  • Low warpage curing methodology by inducing curvature
    Patent number: 11929260
    Abstract: Embodiments of methods and apparatus for reducing warpage of a substrate are provided herein. In some embodiments, a method for reducing warpage of a substrate includes: applying an epoxy mold over a plurality of dies on the substrate in a dispenser tool; placing the substrate on a pedestal in a curing chamber, wherein the substrate has an expected post-cure deflection in a first direction; inducing a curvature on the substrate in a direction opposite the first direction; and curing the substrate by heating the substrate in the curing chamber.

  • Dose rate measurement systems and methods
    Patent number: 10782422
    Abstract: Techniques are disclosed for systems and methods to detect radiation accurately, and particularly in a highly radioactive environment. A system includes a detector module for a radiation detector and a parallel signal analyzer configured to receive radiation detection event signals from the detector module and provide a spectroscopy output and a dose rate output. The parallel signal analyzer may be configured to analyze the radiation detection event signals in parallel in first and second analysis channels according to respective first and second measurement times and determine the spectroscopy output and the dose rate output based on radiation detection event energies determined according to the respective first and second measurement times.
