Silicon carbide gas distribution plate and RF electrode for plasma etch chamber
Abstract:
A showerhead for use in a capacitively-coupled plasma chamber and made of low resistivity bulk layer coated with CVD SiC. The bulk low resitivity material may be, for example, graphite, Silicon Carbide (SiC), converted graphite, SiC+C, etc. Sintered SiC may be used as the bulk material coated with CVD SiC to provide a showerhead that is suitable for use in a capacitively-coupled plasma chamber.
