Growth of Carbon Nanotubes with NanoFab800AgileTM

Cigang Xu PhD, Development Scientist, OIPT

The Plasma Enhanced Chemical Vapour Deposition (PECVD) process has been employed for the growth of carbon nanotubes, in addition to techniques such as laser ablation, arc discharge and Chemical Vapour Deposition (CVD). PECVD tools provide more flexibility and control compared to a general CVD setup.

What's the wafer temperature?

Mike Cooke PhD, New Product Introduction Manager, OIPT

Ask any chemical engineer what’s the most important process variable, and they are likely to reply, ‘temperature’. When we plasma etch a wafer, or deposit a layer by PECVD, is the temperature just as critical? In plasma processes, most of the chemistry is driven not by the surface temperature, but by the electron temperature in the plasma.
