在白色LED中使用的蓝色LED芯片及蓝光光驱光源用蓝紫色半导体激光器,目前新型的GaN基板有望使这些GaN类半导体发光元件的性能得到大幅提高。而在该领域,日本业界最大厂商住友电气工业最近实现了新型GaN基板的大型化,并即将推出产品。该产品就是采用GaN结晶的“半极性面”及“非极性面”的、口径为2英寸的GaN基板。其中,采用非极性面的基板2010年内样品供 The blue LED chips used in white LEDs and the blue-violet semiconductor lasers used in Blu-ray drive light sources are now expected to greatly improve the performance of these GaN-based semiconductor light-emitting devices. In this area, Sumitomo Electric Industries, Japan’s largest maker of semiconductors, recently realized the large-scale production of new GaN substrates and will soon launch its products. The product is a GaN substrate with a GaN crystal of “semi-polar face” and “non-polar face” with a 2-inch diameter. Among them, the use of non-polar substrate samples for the year 2010
