- The term
electronic grade chemicals is used to refer to chemicals used in
electronic industry, particularly in semi-conductor/ micro processor
fabrication or
simply “fab”.
- Solvents are
widely used in electronics for cleansing, stripping, degreasing,
operations, encapsulation.
- A photoresist is a
light-sensitive material used in several industrial processes, such as
photolithography and photoengraving to form a patterned coating on a
surface.
- Gases are found
in ion implanters, diffusion furnaces, expitaxial reactors, etc.
Gases are also used in quality control to detect flaws in electronic
components.
- Dopant, also
called a doping agent, is a trace impurity element that is inserted
into a substance (in very low concentrations) in order to alter the
electrical properties or the optical properties of the substance.
- In the case of
crystalline substances, the atoms of the dopant very commonly take
the place of elements that were in the crystal lattice of the
material. These materials are very commonly either crystals of a
semiconductor (silicon, germanium, etc.), for use in solid-state
electronics or else transparent crystals that are used to make
lasers of various types.
- Electronic
specialty gases (ESGs) used in the manufacture of semi-conductor and
electronic components are often hazardous due to their inherent
physical properties and chemical and biological reactivity.
- Aqueous chemical
cleaning is an example of an effective parts washing method. Its
cleaners are generally environmentally friendly because the
constituents are typically less toxic than solvents and do not
contain ozone-depleting substances (ODSs).
- Photoresists used in
production for DUV and shorter wavelengths require the use of chemical
amplification to increase the sensitivity to the exposure energy. This
is done in order to combat the larger absorption at shorter wavelengths.
Chemical amplification is also often used in electron-beam exposures to
increase the sensitivity to the exposure dose.
- Semiconductor
Production involves pumping feed water, filtration, treating with
chemicals and possibly heat, then reverse osmosis with chemical
treatment, vacuum degasification, storage, ion exchange, ultraviolet
oxidation/sterilization, and finally ultra filter membrane filtration.
- The
electronic-grade hydrofluoric acid of China is limited in terms of
both capacity and output by reason of technical barriers.
- Since 2009,
two 1,000-ton-above projects have put into production successively
in China, referring to 6,000 tons/year electronic-grade hydrofluoric
acid project of Zhejiang Kaiheng Electronic Materials Co., Ltd and
3,000 tons/year electronic-grade hydrofluoric acid project of Fujian
Shaowu Yongfei Chemical Industry Co., Ltd.
- The electronic
industry worldwide stimulated the growing demand for
electronic-grade hydrofluoric acid.
