Abstract:
A method of forming a microcrystalline silicon film by a plasma CVD, which comprises the steps of:providing an electrode for introducing a high frequency electromagnetic wave in a film forming space;introducing a source gas comprising silicon atoms; andapplying a high frequency to the electrode, thereby inducing the formation of a plasma and forming a deposited microcrystalline silicon film on a substrate,wherein the relation of 400<Q<10000 is satisfied when Q is defined as Q=P.multidot.f.sup.2 /d where d (cm) is the distance between the substrate and the electrode, P (Torr) is the pressure of the film forming space during formation of the deposited film, and f (MHz) is the frequency of the high frequency electromagnetic wave.
