3. Semiconductors
Semiconductors
Semiconductors are the foundation of
modern electronics, powering everything
from smartphones to laptops. They are
made of materials that have properties
between those of conductors and
insulators. When impurities are added to
these materials, they become
semiconductors and can be used to
create transistors, which are the building
blocks of modern electronics.

4. The Early Days
The Early Days
The first semiconductor was made in 1947 by Bell
Labs. It was a point-contact transistor made of
germanium. This invention led to the
development of the first commercial transistor
radio in 1954. Silicon was later found to be a
better material for making transistors, and it is
now the most commonly used material in the
industry.

5. How They Work
How They Work
Semiconductors work by controlling the flow of
electrons through a material. When a voltage is
applied to a semiconductor, it can either allow or
block the flow of electrons. This property is used
to create electronic components like diodes,
which allow current to flow in only one direction,
and transistors, which can amplify or switch
electronic signals.

6. Integrated Circuits
Integrated Circuits
Integrated circuits (ICs) are made by
combining many transistors and
other components on a single piece of
semiconductor material. This allows
for the creation of complex electronic
devices like microprocessors, which
are the brains of computers. ICs have
revolutionized the electronics industry
and are now found in everything from
cars to medical devices.

7. Moore's Law
Moore's Law
Moore's Law is the observation that
the number of transistors on a
microchip doubles every two years,
while the cost per transistor is halved.
This law has held true for over 50 years
and has driven the rapid
advancement of the electronics
industry. However, as we approach
the physical limits of semiconductor
technology, it is unclear how much
longer this trend will continue.

challenges arise. One of the biggest challenges is
leakage current, which causes power
consumption and heat generation. Another
challenge is the physical limitations of the
materials used to make semiconductors.
Researchers are working on new materials and
designs to overcome these challenges and
continue the advancement of the industry.
