In electronics, a wafer is also termed as a substrate. It is utilized for the manufacturing of integrated circuits for various electronic devices and solar cells in photovoltaics. Also, a wafer functions as a substrate for microelectronic devices built in the wafer. Because of its wide range of uses and its crucial role in technology, silicon prices have skyrocketed over the past years. But companies, like Wafer World, offer wafers at a reasonable price. There are different kinds of wafer substrates, each with its features and purposes. In this article, we will discuss the different types of wafer substrates and their uses.

Single Element Semiconductors

Silicon is the most common and popular single element semiconductor that’s why silicon prices have become unpredictable over the years. It can be developed into wafers up to 300 mm in diameter.

Silicon on Insulator

There are two types of silicon on insulator: thin-film SOI and thick film SOI. Electronic components only utilize a thin layer of a silicon wafer’s surface; the rest of the wafer functions as mechanical support. SOIs electronically insulate a thin layer of monocrystalline silicon from the rest of the wafer. After this, integrated circuits can then be manufactured on the surface layer of the SOI wafers. The fixed layer of insulation allows SOI-based chips to perform at undoubtedly higher speeds while lowering electrical losses.

III-V Semiconductors

Gallium Arsenide, Gallium Nitride, Silicon Carbide are some examples of III-V semiconductors. GaAs is used in high-speed devices, GaN is used for blue LEDs and Lasers, while SiC is suitable for high temperature and high-power applications.
