Abstract:
A process for depositing a film on a substrate disposed on a pedestal in a processing chamber, said process comprising:introducing a process gas into said processing chamber, said process gas including SiH.sub.4, PH.sub.3, O.sub.2, and argon;controlling said pedestal to a temperature ranging between about 400-650.degree. C.;maintaining a pressure ranging between about 1-25 millitorr in said processing chamber;applying power to an inductively coupled coil to form a high density plasma from said process gas in said processing chamber;biasing said plasma toward said substrate to promote a sputtering effect of said plasma and deposit said film over said substrate, said film comprising a phosphosilicate glass (PSG) film; andwherein at least a portion of said maintaining and applying steps occur simultaneously.
