Compound Wafer
Compound semiconductors are semiconductors made from multiple elements, typically consisting of combinations from groups III–V, II–VI, or IV–IV.Compared to silicon semiconductors, these materials are more expensive and it is more difficult to grow large diameter crystals. As a result, the majority of semiconductor materials have been silicon until now.On the other hand, compound semiconductor wafers possess light-emitting, high-speed, and magnetoelectric properties, making them suitable for applications such as light-emitting diodes (LEDs), laser diodes (LDs), solar cells, field-effect transistors, and Hall sensors.For example, for LED applications, substrates such as Sapphire, Silicon Carbide (SiC), Gallium Arsenide (GaAs), Gallium Phosphide (GaP), and Gallium Nitride (GaN) are used depending on the device characteristics, and thin films (epitaxial layers) are grown on these substrates to form device functions.

III-V Compound Wafer
Overview
III–V compound semiconductors are semiconductors made from group III and group V elements.Typical group III elements include Aluminum (Al), Gallium (Ga), and Indium (In), while typical group V elements include Nitrogen (N), Phosphorus (P), Arsenic (As), and Antimony (Sb).Compounds such as GaN (Gallium Nitride), AlN (Aluminum Nitride), and InN (Indium Nitride), which use nitrogen as the group-V element, are specifically called nitride semiconductors.
Key Features and Advantages
Since many III–V compound semiconductors are direct energy gap semiconductors, they are used in light-emitting devices such as light-emitting diodes (LEDs) and laser diodes (LDs).In addition, they have bandgaps different from that of Silicon (Si), making them suitable for photodiode and other light-receiving elements.Moreover, due to their high-speed characteristics, they are widely applied in electronic devices such as power amplifiers and switches for high-frequency circuits in mobile phones and wireless LANs, making them materials that play an active role in everyday life.
