6'' 8'' Ultra Thick SiO2 10um 20um 25um Dry Wet Oxide Layer 0.1μm
25μm
Description:
Silicon oxide is a compound composed of silicon and oxygen that has
many forms and uses. Silicon oxide can form a protective film on
the surface of silicon, which is a natural oxide layer formed by
the reaction of silicon with oxygen or water molecules, with a
limited thickness 12. Silicon oxide can also be obtained by high
temperature reaction or sublimation method, there are white or
brown crystals or powders, insoluble in water, can be dissolved by
hydrofluoric acid or alkali solution, has strong reducibility,
often used in the preparation of optical glass and semiconductor
materials.
Features:
Silicon dioxide is an inorganic compound with the chemical formula
SiO2. Silicon atoms and oxygen atoms are arranged in a long-range
order to form crystalline silicon dioxide, and short-range order or
long-range disordered arrangement to form amorphous silicon
dioxide.The simplest form of silicon dioxide is SiO2, but SiO2 does
not represent a simple molecule (only the ratio of the number of
atoms of silicon and oxygen in the silicon dioxide crystal). Pure
natural silica crystal, is a hard, brittle, insoluble colorless
transparent solid, often used in the manufacture of optical
instruments.

Application:
Silicon dioxide itself can also be used as an insulator and
dielectric material in integrated circuit capacitors, the main role
is isolation, in the process of making circuits, can prevent the
diffusion of impurities, in transistors and integrated circuits
used as a masking film and protective layer for impurity diffusion.
In the production process of integrated circuits, it is usually
necessary to finally connect the scattered diodes, audiodes,
resistors and other components with aluminum strips, and the places
that do not need to be connected can be covered with silica. In
addition, silica can also be used to make optical fibers to carry
information over long distances.
