  growing, the rest is heating up and cooling down the furnace.... You have to take some time to heat up the graphite parts, and the other part is...you determine the defects inside the crystal by the cooling-down time, and you can control the defect growth by controlling the temperature during cooling...
• Crystalline Silicon Solar Cell Manufacturing (.pdf)
  logistical challenge involving. extensive downtime for periodic maintenance, large numbers of. spare parts, multiple drums of waste and replacement oil, and. numerous technicians. There is a growing trend among silicon manufacturers to use. dry pumps on crystal pullers and growth furnaces since...
• FEA for the factory
  . Yellow areas are partially solidified and red areas are liquid. In a single-crystal casting simulation, the different colors represent different grain orientations of the metal. The cast metal starts solidifying at the cool end while the dendrites of the crystal grow towards the heated end (the pigtail...

  distribution is. determined by stage two reduction. In both stages, grain morphology transformation mechanism follows. nucleation of product phase and product phase crystal growth via chemical vapor transport. Volatile. molybdenum oxide monohydrate, MoO2(OH)2, is the gas phase responsible for the chemical...

  , these high-temperature anneals are performed in vacuum furnaces, either with refractory-metal resistively heated elements or through RF-induction heating. For temperatures above 1600 C, the surfaces of the production wafers must be protected by sandwiching them with SiC dummy wafers or by maintaining...

• Induction Heating for the Aerospace Industry
  technology has played a key role in helping manufacturers meet these demands. Induction melting, for example, is used in vacuum furnaces to produce single- and poly-crystal turbine blades. Induction melting is also used in cold-crucible (autocrucible) solutions that result in exceptionally high purity...

• MICRO:Outlook 2000 (Nov '99)
  By 2002, we will have the majority of production in copper. But I will go a little bit farther than that. By maybe 2002 maybe earlier, maybe 2003 I will assume that at least 90% of worldwide chip manufacturing will use copper rather than aluminum. The reason for that is not just because...
