什么是倒装LED芯片?倒装LED芯片成主流趋势

  • 2015-04-03 10:38:16

近年来中国、美国、欧盟等全球多个国家及地区陆续实行“禁白”政策,LED节能灯泡的市场得到进一步推广,且LED照明产品价格持续下降,这些均直接带动LED照明渗透率的快速提升。从2014年开始的3到5年内,LED照明产业将会迎来爆发性增长,进入“黄金三年”。 而作为领头环节的上游LED芯片的制造技术和对应的封装技术共同决定了LED未来在照明领域的发展速度。

  倒装LED芯片应势而出

  随着上游芯片产能不断扩产,封装行业已经步入微利时代,许多企业为了抢夺客户大打价格牌,激烈的价格竞争和无序的业内生态链促使行业开始需求新的封装工艺。

  而具有提升发光效率以及提高散热能力等优势的倒装LED芯片技术的革新与应用正是当今封装企业专注研发的重点。

  与正装芯片相比,倒装焊芯片(Flip-chip)具有较好的散热功能;同时,我们有与倒装焊适应的外延设计、芯片工艺、芯片图形设计。芯片产品具有低电压、高亮度、高可靠性、高饱和电流密度等优点;加上能在倒装焊的衬底上集成保护电路,对芯片可靠性及性能有明显帮助;此外,与正装和垂直结构相比,使用倒装焊方式,更易于实现超大功率芯片级模组、多种功能集成的芯片光源技术,在LED芯片模组良率及性能方面有较大的优势。光效方面,倒装结构避开P电极上导电层光吸收和电极遮光,还可以通过在p-GaN设反光层,而提高光效。

  长期而言,倒装芯片将减少封装环节的工艺,对封装业产生一定的挤压。另外,倒转芯片可能导致芯片的驱动功率增加,变相降低照明背光应用对于芯片的实际消耗,而改变照明应用对于芯片的长期需求。
