Abstract
Disclosed is method and apparatus for distributing a chemical over the surface of a substrate. The method includes depositing the chemical on a portion of the surface of a substrate near the center of the substrate. The method further includes controlling the temperature of the surface of a substrate so that the viscosity of the chemical is calibrated to cause the chemical to be deposited on the surface of the substrate in a substantially uniform manner.
