据物理学家组织网近日报道,一种新的制造技术有望大幅降低发光二极管(LED)的生产成本,进一步推动其普及进程。这项由西门子旗下子公司欧司朗光电半导体公司的研究人员所进行的研究,成功在硅衬底上生产出了氮化镓LED芯片,取代了目前普遍使用的较为昂贵的蓝宝石衬底。硅是一种标准半导体材料,作为LED衬底具有尺寸大、成本低、易加工、导 According to a recent report by the Physicist’s Organization Network, a new manufacturing technology is expected to significantly reduce the production cost of light-emitting diodes (LEDs) and further promote their popularization. The research, conducted by researchers at OSRAM Opto Semiconductors, a subsidiary of Siemens, succeeded in producing gallium nitride LED chips on silicon substrates, replacing the more expensive sapphire substrates commonly used today. Silicon is a standard semiconductor material, as a LED substrate with large size, low cost, easy processing,
