What is an INP Wafer (Indium Phosphide)?

An Indium Phosphide wafer (InP) is a semiconductor material that crystallizes in a face-centered cubic (zincblende) structure, similar to many other III-V semiconductors. It is composed of indium and phosphorus and shares some properties with GaAs and silicon, though it is considered a niche product. InP is notable for its long-lived optical phonons, among the longest in any zincblende compound, making it valuable in power electronics and photovoltaic devices.

III-V semiconductors are compounds that were formed by the elements of groups 3 and 5 of the periodic table of Mendeleev. Thanks to their unique properties, we can use the compounds in many areas such as telecommunication and microelectronic systems or as a substrate for various epitaxial applications. They are perfect for integrated photonic applications

 What are Indium Phosphide Details? 

  • Indium Phosphide is a binary semiconductor which includes elements indium (In) and phosphorus (P).
  • Indium Phosphide is known for its superior electron velocity, which is crucial for applications that require high-frequency and high-power electronics.
  • The molecular weight of InP is 145.792 g/mol, and it has a high melting point of 1062 °C (1943.6 °F).
  • InP plays a pivotal role in generating laser signals and converting them back to electronic form, making it the primary material for these critical functions.

Our InP wafers are produced based on the Czochralski method. They are doped with elements such as zinc, tin, sulfur or iron.

We also offer a wafer surface finishing services like polishing or etching.
