Xiamen Powerway Advanced Material Co.,Ltd (PAM-XIAMEN), the leading developer and supplier of compound semiconductor crystal and wafer, today announces availability of InGaN substrate materials. InGaN is the key compound semiconductor material used for the fabrication of blue, green, and white light emitting diodes (LEDs),GaN-based ultra violet (UV), bblue laser diodes (LDs) and solar photovoltaic application. Indium gallium nitride is as the light-emitting layer for these light-emitting devices and determine device efficiency, light output power and lifetime. InGaN substrates are needed for InGaN-based device epitaxial structures and to improve device performance.
“Our success of the InGaN material expend our nitride business,and move forward to the LED and solid-state lighting market fastly,” said Dr. Shaka “Now we are second manfuacturer to offer InGaN template after TDI,we will continue to offer this material to our current customers for green light LED application, our continuous research would focus on solid state lighting application,of course we will expend new customers for other application.”
“Now we can offer wide range nitirde semiconductor materials,including GaN, InGaN, InN, and AlN epi wafer with a wide range of deposition rates, various doping levels, wide composition ranges, and low defect densities, to meet our various customer's requests,including researcher and device foundry",added Victor Chan, a senior marketing manager for the company.
New substrates consist of an InGaN layer deposited on 2-inch GaN/sapphire template. In content in the InGaN layers ranges from 10 % to 40 %. Targeted applications are high brightness UV, blue, and green light emitting devices including light emitting diodes and, potentially, blue and green laser diodes. Currently InGaN template substrates are available in limited quantities. Available InGaN thickness:100-300nm.
Crystal Quality:Our side technology sector to the XRD data of a reference in InGaN as follows: (4um of GaN growth on the Template InGaN)
50nm InGaN, 20% In composition, the rocking curve FMHW (00.2) ~ 460 arcsecs (10.2) to 610 arcsecs(Test equipment is a Bruker D8 high-resolution X-ray diffraction).But please note that of InGaN XRD data strongly depends on the thickness, the thickness of 200nm, of InGaN crystalline quality would be higher.Though the Raman data is also a measure of crystal quality, but less accuracy than the XRD precision, so we generally measure the quality of the crystal without Raman test.
