Methods and equipment are provided for processing sheet-like substrates.
The methods and equipment are useful for depositing coatings on both
major surfaces of a sheet-like substrate. Also provided are substrates
with coatings on both major surfaces. Preferably, the coatings on the
opposed major surfaces of a substrate have different structures, yet
share a common structural sequence of at least two film regions, and in
some embodiments at least three film regions.
