InP基板

PAM-XIAMEN, a leading InP wafer supplier, offers Compound Semiconductor 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. The InP wafer orientation (111) or (100) is available. And the dopants can be Sulphur, Sn(Tin), Zinc or customs. The Laser Mark as specified on backside of InP wafer along with primary flat. The orientation with slight deflection angle is available, such as (100)0.075° towards [110]]±0.025°.

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., 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. Indium phosphide wafers are used in high-power and high-frequency electronics [citation needed] because of the superior electron velocity with respect to the more common semiconductors silicon and gallium arsenide. The InP wafer size we can offer is 2”, 3” and 4”, and the InP wafer thickness will be 350~625um.

About InP Wafer Application

As a new type of compound semiconductor material, InP wafer market share is increasing gradually. Due to the excellent indium phosphide properties, the performance of microwave power source devices, microwave amplifiers and gate FETs fabricated on InP material will be better than those fabricated on existing gallium arsenide materials. Indium phosphide heterojunction lasers are also extremely promising light sources in optical fiber communications.

InP wafer fabrication for devices, like growing millimeter wave microelectronic devices and optoelectronic device materials for optical fiber communications, is widely used. With the continuous improvement of device performance and the reduction of device size, the quality requirements for indium phosphide wafers are getting higher and higher. Therefore, the InP wafer process is optimizing gradually.

The the typical values is see below data:

Peak Lambda(nm) Peak Int FWHM(nm)
1279.4 7.799 48.5
1279.8 5.236 44.6
