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
