Deposition of polysilicon using a remote plasma and in situ generation of UV light

A processing apparatus and method for depositing doped or undoped polysilicon on a wafer utilizing a single process chamber to heat the wafer, provide a silicon comtaining gas, and if desired, an appropriate dopant gas to the chamber with the excitation energy being provided by either or both of a r...

Beschreibung
Zusammenfassung:	A processing apparatus and method for depositing doped or undoped polysilicon on a wafer utilizing a single process chamber to heat the wafer, provide a silicon comtaining gas, and if desired, an appropriate dopant gas to the chamber with the excitation energy being provided by either or both of a remotely generated plasma form and illumination of the wafer with an in situ generated ultraviolet energy.
