  are then melted in the quartz crucibles of the rows of crystal pullers in the factory. Then crystal growth and the pulling of the ingots takes place, followed by the sawing of the silicon rods, edge rounding of the newly sliced wafers, grinding and lapping, polishing, and cleaning. The process concludes...

  and MSZW information allows suitable zones of operation to be identified. To encourage growth and minimize nucleation, crystallization should occur within the metastable zone. Seeding the process can help. Seeding can be a useful method for increasing crystal size and ensuring a robust process...
• MICRO: Reality Check
  . The cost of thin-film-transistor liquid-crystal display (TFT-LCD) panels has been steadily dropping, and significant price reductions of LCDs have led to their explosive growth. For example, for LCD monitor sizes of 20 in. and smaller, the price per diagonal inch has dropped from about $100 before 2001...

  substrate and the space between them is filled with liquid crystal. Finally, in the module assembly process, driver ICs, backlighting, and other components are attached and connected to the panel. The FPD industry is extremely competitive and cost-sensitive, with growth in demand linked to lower...

  crystals crystal growth. By manipulating the relative magnitude of these mechanisms, it is possible to design a robust crystallization with a desirable final product particle size. For example, if small crystals are desired to increase bioavailability, or to avoid a milling step, nucleation should...
• Controlling Crystallization through Modeling
  This quick, one-time registration gives you access to members-only site benefits. Controlling a product s crystal size distribution (CSD) is one of the key challenges in drug manufacturing. CSD control is critical to successful crystallizer operation and to product quality and purity, as CSD often...
• Inertial Sensing for Hard Disk Drive Drop Protection (.pdf)
  The worldwide growth rate for portable electronic products, which are more and more likely to contain a hard disk drive (HDD), is impressive. Earlier this year, the IT market research specialists at IDC reported that worldwide mobile phone shipments totaled 194.3 million units in the fourth quarter...

• Ensuring Better Control of Granulation
  By Rakesh P. Patel, PhD, and A.M. Suthar, Gnpat University, India High-shear mixers may exhibit a narrow margin between the liquid required to obtain granule growth and the amount that results in an over-wetted mass. Because of the intensive wet massing and densification of the granules, less...
