Abstract
An apparatus for delivering a fluidic media to a wafer includes a housing defining a process chamber. A fluidic media delivery member is coupled to the process chamber. A rotatable chuck is positioned in the process chamber. The rotatable chuck has a wafer support surface coated with a coating material. A vacuum supply line is coupled to the rotatable chuck.

An apparatus for delivering a fluidic media to a wafer, comprising:
- a housing defining a process chamber;
- a fluidic media delivery member coupled to the process chamber;
- a spin chuck positioned in the process chamber, the spin chuck having a wafer support surface coated with a coating material;
- and
- a vacuum supply line coupled to the spin chuck.
An apparatus for delivering a fluidic media to a wafer, comprising:
- a housing defining a process chamber;
- a fluidic media delivery member coupled to the process chamber;
- a spin chuck positioned in the process chamber, the spin chuck including a wafer support surface and a skirt positioned at a periphery and in a non-planar relationship to the wafer support wafer surface;
- and
- a vacuum supply line coupled to the spin chuck.
A wafer processing apparatus, comprising:
- a housing;
- a first wafer transporter positioned in the housing;
- a second wafer transporter positioned in the housing;
- and
- a process station coupled to each of the first and second wafer transporters, the process station including a plurality of wafer processing modules, each of a module including a spin chuck having a wafer support surface coated with a coating material.
A method of reducing contamination of a wafer, comprising:
- providing a spin chuck with a wafer support surface;
- positioning the spin chuck in a treatment chamber;
- and
- applying a coating material to the wafer support surface.
A method of applying a material to a wafer, comprising:
- providing a spin chuck with a wafer support surface coated with a coating material;
- positioning the wafer on the wafer support surface;
- spinning the spin chuck in a process chamber;
- delivering the material to the wafer while the spin chuck is spinning;
- and
- forming a uniform layer of material on the wafer.
