 Polycrystalline Silicon |
 Used in semiconductor production.
polycrystalline silicon is one of the purest
materials known to man.
With "11-9" purity, or purity of 99 percent followed
by nine nines, polycrystalline silicon is used
throughout the semiconductor industry for wafers,
the building blocks of semiconductor devices.
Already one of the world's largest makers of this key
material, Tokuyama is taking steps to further boost
output capacity and enhance quality in anticipation
of more growth in demand.
