Silicon manufacturing is an important part of semiconductor fabrication, especially because one of the materials used to produce a semiconductor is silicon. Semiconductor devices have established a wide variety of applications because of their affordability, reliability, and durability. They can be found in power devices, light emitters, compactness optical sensors, and solid-state lasers. If your next project involves the use of semiconductors, then knowing the different materials used to produce one might help you decide on which type of semiconductor is suitable for you. Here are the semiconductor device materials and their applications:


Silicon (Si) is the most commonly used material in the production of semiconductor devices because of its low raw material cost and simple manufacturing process. Silicon’s ability to perform well even at high-temperatures is what makes it desirable. The silicon wafer used in semiconductor device fabrication has a diameter of 300 mm or 12 in. Silica sand goes through silicon manufacturing to produce extremely pure single crystal silicon.

Gallium Arsenide

Gallium Arsenide (GaAs) is used for high-speed devices, except that it has been challenging to create large-diameter bowls of this material, which limits the wafer diameter sizes into smaller sizes compared to silicon wafers. This makes its mass production more expensive compared to silicon.


Germanium (Ge) used to be the most commonly used material in semiconductor fabrication, but because of its thermal sensitivity, more companies opt for silicon. Today, germanium is combined with silicon for extremely high-speed devices.

Common Semiconductor Device Applications

Semiconductor devices in the form of a transistor can be utilized as a component of logic gates, which is beneficial in designing digital circuits, like microprocessors. It also acts as a switch (on-off). It is also used in solar cells, light-emitting diodes as displays in digital clocks, microwaves ovens, and other electronic devices, and semiconductor lasers in automatic doors, bar-code readers, and fiber-optic communications devices.
