Advances in semiconductor
performance and circuit miniaturization
Semiconductors are vital to the operation of products
large and small that we rely on for our daily activities.
These chips control everything from PCs, mobile
phones and digital cameras to home appliances and
automobiles.
Moore’s Law symbolizes the remarkable speed of
advances in semiconductor performance. The law
states that transistor density on semiconductor chips
will double approximately every 18 months.
Semiconductor devices are made by using ultraviolet
light to project circuit patterns on the surface of silicon
wafers. Hoya used its decades of expertise in optical technology to start a lithography business
in the 1970s for semiconductor manufacturing equipment. By fabricating the mask blanks used
to make semiconductor photomasks, Hoya has played an important role in the rapid advances in
semiconductor devices expressed by Moore’s Law.
