How Integrated Circuits Work

							?Integrated circuits are used from everything from the microwave to the computer.
But how are they constructed, and what are they constructed from, and most
importantly, how do they make things work?

Integrated circuits are constructed with a number of materials that have been proven
to be effective in creating, regulating, and monitoring electrical flow. They consist of
a number of diodes, transistors, sensors, and microprocessors. Diodes are electronic
devices that regulate flow in the circuit and are essential to the functionality of
integrated circuits. Transistors are devices that are used for a number of functions
such as voltage stabilization and amplification. By being able to place numerous
transistors on one tiny chip, circuits can be constructed for many more types of
equipment. Integrated circuits are getting more and more complex, with more
components on one chip that ever. Integrated circuits have thousands and even
millions of transistors on a single chip.

Microprocessors are the most important component to an integrated circuit, which
provides memory, and allows ICs to control everything from computers to
microwaves. Memory chips are actually an entire group of integrated circuits
independent of the Microprocessor. RAM (random access memory) is an integrated
circuit that is used in all computers.

To build an integrated circuit, semiconductors, or the components used to create ICs
are all created from chemical elements proven to be functional in conducting
electrical current. Silicon is the most widely used type of material, though elements
such as Germanium and gallium arsenide are still used for some devices. Silicon is the
most desirable type of material because it is relatively easy to process and has a
temperature range that is ideal for electrical devices. Silicon is used for almost every
component of the integrated circuit. If fact, chip designers actually use the silicon
surface of integrated circuits to create art, or more commonly know as Silicon
Graffiti.

With all these components in place, engineers can place integrated circuits in all types
of electronic equipment, but on the forefront, is definitely the computer chip.
Companies are competing to make the smallest and fastest chips, which increase
overall functionality, and also help to be more cost effective.
