Information
Technology
There seem to be no limits to the evolution of technology—the crystallization of human wisdom.
The microscopic world that has been developed by cutting-edge technology, however,
is also a part of the natural world. Technology, therefore,
is in a certain sense a meeting of the man-made and natural worlds.
Electro-Optics
MASK BLANKS, SEMICONDUCTOR PHOTOMASKS AND LCD PHOTOMASKS
Mask blanks are precisely polished glass plates coated with a thin, metallic light-sensitive film. Etching circuit patterns in
these blanks with an electron beam produces a photomask.
In fiscal 2004, sales of digital consumer electronics such as digital cameras and LCD televisions grew significantly,
demand for mobile telephones and personal computers was strong, and there was a boost in investment at client companies
aimed at development of next-generation products.
