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.

Parameters:

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.
