On the silicon substrate an epitomical layer is made,where IC components are formed subsequently.In an CVDprocess,the silicon substrates places in a vacuum crystal tube are first heated to 1,600°C by high-frequency radio power and then H⒉Cl⒉Si and certain gaseous compounds of As or P is injected into the tube to make a deposit of several um on their surface.Ions of As or P are impurity deliberately added to the singl-crystalline silicon structure to supply electrons that transmit "negative"current in the silicon crystals,which is called n-type silicon.Bcan be added as impurity to produce p-type silicon that supplies holes for transmitting "positive"current.Whether a p--type of an n-type silicon substrate is needed depends on what type of transistors is expected to be manufactured on it:n-p-n type of p-n-p type

Using ethyne as source gas, CNTs were successfully synthesized by CVD method. By comparing different synthesis technics, the influences of parameter to the grow of CNTs, such as catalysts, growth time, reaction temperature and ratio of all kinds of carrier gases were investigated. The results showed that the influence of carrier gas, reaction temperature, and the growth time on synthesis of CNTs was significant. In conclusion, a better condition for carbon nanotube growth was obtained. Through analyzing Raman Spectrum of samples, GM and SWNTs' characteristic peak-RBM was indicated.
