PAM-XIAMEN offers InP wafer – Indium Phosphide which are grown by LEC(Liquid Encapsulated Czochralski) or VGF(Vertical Gradient Freeze) as epi-ready or mechanical grade with n type, p type or semi-insulating in different orientation(111)or(100).

Indium phosphide (InP) is a binary semiconductor composed of indium and phosphorus. It has a face-centered cubic (“zinc blende”) crystal structure, identical to that of GaAs and most of the III-V semiconductors.Indium phosphide can be prepared from the reaction of white phosphorus and indium iodide[clarification needed] at 400 °C.,[5] also by direct combination of the purified elements at high temperature and pressure, or by thermal decomposition of a mixture of a trialkyl indium compound and phosphide. InP is used in high-power and high-frequency electronics[citation needed] because of its superior electron velocity with respect to the more common semiconductors silicon and gallium arsenide.

Telecom/Datacom Application

Indium Phosphide (InP) is used to produce efficient lasers, sensitive photodetectors and modulators in the wavelength window typically used for telecommunications, i.e., 1550 nm wavelengths, as it is a direct bandgap III-V compound semiconductor material. The wavelength between about 1510 nm and 1600 nm has the lowest attenuation available on optical fibre (about 0.26 dB/km). InP is a commonly used material for the generation of laser signals and the detection and conversion of those signals back to electronic form. Wafer diameters range from 2-4 inches.


Applications are:


• Company networks and data center

• Fibre to the home

• Connections to wireless 3G, LTE and 5G base stations

• Free space satellite communication
