  • Spatially Resolved Spectroscopy

    Hy-Ternity ® - Indatech

    Standard Visible and Near-Infrared (NIR) Spectroscopy performs one single spectrum measurement per sample. Spatially Resolved Spectroscopy (SRS) performs measurements at different distances from the illumination point. This approach provides chemical information but also physical one such as particle size and shape, cell density, uniformity and even weight. As a result, the surface analyzed is also much more important which copes for the recommendation of pharmacopeia. In addition, Several research centers have demonstrated the superiority of Spatially Resolved Spectroscopy and multipoint imaging techniques over standard NIR one.

  • DEFECT INSPECTION

    Semilab

    "Bulk Micro Defects," (BMD) is a term commonly used to refer to oxygen precipitates in silicon. In fact, many imperfections in the silicon lattice create defects, and BMDs could be any imperfections including oxygen precipitates, voids, inclusions, slip lines, etc. BMDs go by many names, referring to the problems they cause, how they were created, or their physical characteristics. Examples include COPs (Crystal Originated Particles) and Grown-In Defects.Dislocations can be formed during crystal growth but also at thermal processing of wafers, during CMOS device manufacturing like epitaxial layer growth and implant anneal steps.

  • Envelope Density Analyzer

    GeoPyc 1365 - Micromeritis

    The GeoPyc employs a unique displacement measurement technique that uses Dry Flo, a quasi-fluid composed of small, rigid spheres having a high degree of flow-ability. The sample is placed in a bed of Dry Flo which is agitated and gently consolidated about the sample. The GeoPyc collects the displacement data, performs the calculations, and displays or prints the results. The GeoPyc automatically determines the volume and density of a solid object by displacement of Dry Flo, a solid medium. The medium is a narrow distribution of small, rigid spheres that have a high degree of flow ability and achieve close packing around the object under investigation. The particles are sufficiently small that during consolidation they conform closely to the surface of the object, yet do not invade pore space.
