Polishing Technologies
Glass substrates are ground and polished to a designated degree of
thickness. The grinding process involves the use of diamond
grindstones that smooth out bumps, hollows and other irregularities
in the substrate. On top of this, polishing processes use special
polishing powders to produce an ultra-smooth surface. Hoya’s highest
precision products are the mask blanks and photomasks used in the
production of semiconductors. These products are polished flat to an
accuracy of one thousandth of a millimeter, with a surface roughness
of only one millionth of a millimeter.
Thin Film Technologies
Hoya developed its surface treatment technologies beginning with
anti-reflective coatings for optical filters. It has continued to refine
these technologies by developing coatings for eyeglass lenses, and
today it employs new technologies in spattering processes for
mask blanks and glass magnetic-memory disks.
Optics Design
Hoya has amassed a considerable armada of optical lens design
technologies over the years. The Company rigorously controls the
degree of refraction, dispersion and light transmittance, as well as
the homogeneity of the glass, and fine-tunes these characteristics
to create optical products that meet the very different needs of
each individual client. Hoya’s advanced lens design technologies
contribute to the development of higher resolution displays with
greater image quality for both digital cameras and mobile phones
with cameras. These advanced technologies are also seeing use in
the design of eyeglass lenses.
Precision Processing (Lithographic Technologies)
The photomasks employed in the production of semiconductors
stand at the pinnacle of the world of high-tech products that
require ultra-precise processing technologies. Leading-edge
lithographic technologies are used to etch extremely fine circuit
patterns with line widths of only several tens of nanometers. On a
daily basis, Hoya is challenging the limitations of technologies and
pushing back the frontier of physical materials, providing assistance
to semiconductor makers who continue to develop products that
perform better and achieve ever greater integration.
