The principle of inductively coupled plasma (ICP) and perspective of ICP development are reviewed. Multispiral coil ICP (MSC-ICP), which has the advantages of low inductance, high efficiency, and excellent uniformity, is discussed in detail. Applications to thin film processing technologies and the future prospects of ICP are also described. A tube CVD reactor is shown schematically below. The tube is typically fabricated of quartz, and of large enough diameter to load the wafer size desired with some margin. The tube is inserted in a resistively heated box. The box typically has 2 or more independently controlled heating zones to allow some control of axial temperature along the ...

According to whichever option you choose, the placement of the label will differ: if you choose 0, the label will always be parallel to the axis (which is the default); If you choose 1, the label will be put horizontally. Pick 2 if you want it to be perpendicular to the axis and 3 if you want it to be placed vertically… Wafer boats include three or more boat rods having recesses ground into them to support wafers. Recess heights are increased relative to conventional boats in order to reduce shadow marks in layers deposited by chemical vapor deposition (CVD) employing BTBAS or other CVD processes that are particularly sensitive to shadow effects from the support recesses.

Demonstrate how to calculate the load on the sling using the load angle factor for various load angles. Explain the proper use and limitations of the various rigging equipment and hardware (wire rope, synthetic web slings, shackles, eyebolts, hooks, etc.). Identify the components and describe the characteristics of wire rope and synthetic slings. In this apparatus, the wafers are displayed vertically on a horizontal, circular quartz support. The gases are introduced at the top of the reactor, through a number of feeding tubes, then flow downwards, parallel to the wafers surfaces and are exhausted at the bottom.

Tube Reactor Overview - Enigmatics
Vertically aligned carbon nanotube arrays (VANTAs) are a unique microstructure consisting of carbon nanotubes oriented along their longitudinal axis normal to a substrate surface. These VANTAs effectively preserve and often accentuate the unique anisotropic properties of individual carbon nanotubes and possess a morphology that may be precisely controlled. Amorphous silicon films, grown by low pressure chemical vapour deposition (LPCVD) in a hot-wall reactor at temperatures around and below 500°C and at pressures of 100 mTorr, were investigated ...
