Undoped, Indium Antimonide Wafer, 3”, Dummy Grade
PAM-XIAMEN manufactures high purity single crystal InSb(Indium Antimonide) Wafers for photodiodes or photoelectromagnetic device, Magnetic field sensors using magnetoresistance or the Hall effect, fast transistors (in terms of dynamic switching) due to the high carrier mobility of InSb, in some of the detectors of the Infrared Array Camera on the Spitzer Space Telescope. Our standard wafer diameters range from 1 inch to 3 inches, wafers can be produced in various thicknesses and different orientations (100),(111),(110) with polished wafers and blank wafers. PAM-XIAMEN can produce wide range grades: prime grade, test grade, dummy grade, mechanical grade, and optical grade. PAM-XIAMEN also offer InSb material to customer specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies.
