It
is probable that most people have come across and even used silicon wafer in their day to day
lives. It may not have been deliberate; however, for people who have used
devices such as computers and smartphone, they have certainly used this
equipment.
Silicon Wafer! What is it?
Prime-grade silicon substrate is
a material used for producing semiconductors, which can be found in all types
of electronic devices that perks up the lives of people. Silicon comes second as
the most common element in the universe; it is mostly used as a semi-conductor
in the technology and electronic sector.
Most
individual have had the opportunity to encounter a real silicon wafer in their
life. The super-flat desk is refined to a mirror-like surface. It is also made
of subtle-surface irregularities which make it the flattest object globally.

It
is also extremely clean, free of pollutions and micro-particles, qualities that
are essential in making it the perfect substrate materials of the contemporary
semi-conductors. There are various methods utilized in silicon fabrications
counting the horizontal gradient freeze process, vertical Bridgeman method and
the pulling method.
All
through the growth process dopants can be included to amend the purity of the
silicon wafer depending on its manufacturing purpose. The pollutants can alter
silicon electronic properties which are essential depending on the reason of
its production.
Some
of the silicon dopants that can be added throughout the growth procedure
include aluminium, boron, nitrogen, indium, and gallium. A semi-conductor can
be regarded as either deteriorates depending on the level the silicon wafer
was, when the dopants were added. Visit
