竞技宝ios下载_竞技宝app下载_竞技宝官网app (InP) Substrates


Vital produces high quality 竞技宝ios下载_竞技宝app下载_竞技宝官网app (InP) wafers, from 2”to 4” in diameter for telecommunications and microelectronics applications. InP wafer are provided un-doped, Fe-doped, S-doped , and Zn-doped.

Market and Application

InP is an important III-V compound and semiconductor material with advantages of high electron mobility, good radiation stability, and large band gap. 竞技宝ios下载_竞技宝app下载_竞技宝官网app has particular advantage in two applications:
  1. Photonics: Emission and detection capacities with more than 1,000nm wave length
  2. RF: High-speed and low noise performance in high frequency RF applications. InP is the first choice for performance-driven niche markets in military communication, radar, test equipment, and radiation measurement.
