General
- In
chemistry a nitride is a compound of nitrogen with a less
electronegative element where nitrogen has an oxidation state of
-3.
-
Classification of nitride include: salt like, e.g. lithium
nitride, Li3N, beryllium nitride, Be3N2
, covalent, interstitial e.g. titanium nitride, TiN ,
intermediate e.g. iron nitride, Fe2N
Technology
- Recent
advances in nitride based white light sources and on electronic
devices that can operate at high temperatures have enthused
researchers to work more vigorously on different aspects of
III–nitrides such as gallium nitride (GaN), indium nitride (InN)
and aluminium nitride (AlN).
-
Low-temperature bis(tertiary-butylamino)silane (BTBAS) -based
nitride spacers showed device performance improvement over DCS
based nitride spacers.
Application
- Silicon
Nitride (Si3N4) is a relatively new member of the advanced
ceramics family.It is used in many varied applications, but
lends itself particularly to applications where high
temperatures are involved.
- Silicon
Nitride components are useful for the whole production process
of the aluminium parts.
- Nitride
deposition with SiH4/NH3/N2 has been widely used in compound
semiconductor industry.
Market
- Demand for
aluminum nitride (AlN) substrates is increasing as a heat
dissipating & insulation substrate for power modules used for
inverters that control the turning of a motor and so on.
- The market
of aluminum nitride (AlN) substrates is expected to grow
at about 7 to 10 percent annually, especially with the growth of
hybrid cars in the auto industry field, and solar power
generation and wind power generation in the energy field.
- The
largest market for silicon nitride components is in
reciprocating diesel and spark ignited engines for combustion
components and wear parts.
