Chips its 
uses and 
Importance
Introduction
A Silicon Chip is an integrated circuit 
that serves as the primary component of 
all computing devices. As the name 
suggests, silicon chips are made 
primarily from silicon.

Valuable Property 
of Silicon
A substance that is only second to 
Oxygen in being the most abundant 
substance on earth. Silicon is valued for 
its properties of semi-conduction and 
how conveniently available it is all over 
the globe.

Silicon chips
Silicon chips are the brain of the device; 
directing all its functions through its in-
built components. Examples include 
tablets, smart phones and laptops.

How Silicon Chips 
Are Made?
 A silicon wafer is basically a slice of 
purified silicon on with silicon chips 
are built and arranged in a grid 
formation.

Process
 This is part of a series of steps 
involved in the making of the silicon 
chip. It all begins when silicon is first 
purified, melted and then cooled to 
form ingots

Doping
 Doping is a process whereby special 
impurities are added on to the silicon 
to give it the desired semi-conduction 
capabilities.

Semi-conduction 
capabilities
 Before the doping procedures can 
begin, the wafers must be buffered in 
order to get rid of any dirt that might 
have accumulated during the cutting 
process.

Sputtering
 The components made can either be 
p-type components or n-type 
components. 
 Doping can be done using different 
procedures. One well known one is 
called sputtering.

Expectations from 
Technicians
 Technicians are expected to wear 
special suits that are meant to 
prevent lint, hair, dust or any other 
substances from jeopardizing the 
process. 
 This is to ensure that all silicon chips 
are of high quality and that they suit 
the desired application.
