Semi-Insulating ,InP ( Indium Phosphide) Crystal Wafer , 3”, Dummy Grade

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.

What is the InP Process?

InP wafers must be prepared prior to device fabrication. To start, they must be completely cleaned to remove any damage that might have occurred during the slicing process. The wafers are then Chemically Mechanically Polished/Plaranrized (CMP) for the final material removal stage. This allows for the attainment of super-flat mirror-like surfaces with a remaining roughness on an atomic scale. After that is completed, the wafer is ready for fabrication.

Basic Parameters

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:

• Long-haul optical fibre connections over great distance up to 5000 km typically >10 Tbit/s

• Metro ring access networks

• Company networks and data center

• Fibre to the home

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

• Free space satellite communication
