  • ZEDFA1403P22
    Conclusion Due to the capability of the magnetic field to penetrate through all materials used in semiconductor manufacturing, the MCI technique is a good choice for nondestructively detecting defects in 3-D devices. … a double-stacked 3-D device, even when the full stack is inside the intact molding compound.
  • ZEDFA1303P42
    Sonix Introduces Molded FlipChip Imaging Enhancement Sonix, Inc. (Springfield, Va.) introduced its Molded Flip-Chip Imaging (MFCI) enhancement, which improves image quality and defect detection in molded flip-chips and packages with polyimide (PI) layers. To improve the thermal properties (conductivity and expansion) of semiconductor packages, filler particles are added to compounds used for overmolding and underfill.

    To the further Klfirung of these questions, the Prozel3 4He(w)aT with two different Mel3methoden with a coincidence of two semiconductor detectors and with a CsJ(T1)-Spektrometer with pulse mold discrimination in the energy sector yon was reinvestigated 23 … Although an indubitable detection of occurring structures not geffihrt can become because of statistical errors , the occupation of discrete levels the signs ffir follows by the comparison of several unabh/ingiger MeBreihen.
  • Review of production of microfluidic devices: material, manufacturing and metrology
    There are wide varieties of configurations to detect the defects in production, and almost all configurations are from semiconductor , MEMS and optics industries. Figure 6(a) shows one side of a microchannel of a silicon mold obtained with dark field …
  • Consideration of mechanical chip crack on FBGA packages
    Semiconductor chips inside the mold compound were completely desroyed by one or more cracks after assembly as shown in Figure 1. No external mold cracks, separations, warpages or coplanarity defects were detected on these modules containing cracked chips.
  • Application of advanced after-laying test to long-distance 275 kV XLPE cable lines
    Extrusion type molded joints (EMJ) are also screened for defect ,s,such as contamination of impurities and exter- nal damage, by surface inspection employing video system with a charge coupled device (CCD) cameras, and by a high-sensitivity X-ray inside observation … … current technology level of this screenig process [3], it is virtually impossible to detect all defects arising … Defects in EMJ to be produced during jointing work are contamination of impurities (metal impurities, semi- conductor impurities and fiberous impurities), protrusions of the semiconducting layer, voids, external damage, and debonding i.e. insafficent bonding of cable insulation and EMJ reinfarcing insulation.

  • Renewable energies
    The photocurrent IPh generated by light irradiation is sensed in the replacement circuit diagram in form of a current source in parallel lying to the diode D. The series resistance RS sits down together of the resistance of contacts and supplies as well as that of the semiconductor material itself. The parallel or shunt resistance RP considers the "leakage currents" through defects or on the edges of …
