The Third-Generation infrared detectors characterized as multicolor, large array, high performance and low cost have become the development goal of the infrared detectors. InAs/GaInSb Type-II infrared materials has special broken band structure and materials merits, furthermore, the materials has been widely applied in the area of large array long wavelength infrared detectors、high temperature mid-wavelength infrared detectors、middle wavelength dual-band infrared detectors and ultra-long wavelength infrared detectors. The superior devices performance with high detectivity and excellent uniformity verified the technology superiority and maturity. It has become one of the best choices as the Third-Generation infrared detectors in the world. In this paper the material advantages, the technique issues and development status has been introduced in order to advance the development of InAs/GaInSb type-Ⅱ technology in our country.
