【元件】 ROHM确立业界超小短波红外器件的量产技术,适用于便携设备和可穿戴设备等新领域的感测应用
全球知名半导体制造商ROHM(总部位于日本京都市)针对需要进行物质检测的便携设备、可穿戴和可听戴设备,确立了1608尺寸(1.6mm×0.8mm)业界超小的短波红外*1(以下简称SWIR:Short Wavelength Infrared)器件量产技术。
SWIR利用了水、冰和气体等吸收特定红外波长的特性,在感测领域的应用备受期待。这种产品不仅可用来检测物质的有无和成分的多少,还可以用作医疗领域的血氧饱和度和血糖检测装置的光源,在食品领域还可用来检测蔬菜和水果的含水量和含糖量等。另外,在便携设备等的感测应用中,还可通过有机EL显示器进行检测。此外,这种产品在可穿戴设备健康监测等众多领域也已开始发挥重要作用。
在这样的背景下,ROHM利用在可见光LED和近红外LED等化合物半导体的量产过程中积累的生产技术优势,确立了可实现小型表贴封装1608尺寸SWIR器件(发光,感光)的量产技术。对于发光侧的LED,计划推出不同封装形状(模塑型、透镜型)和不同波段(1050nm~1550nm)相结合的10款新机型。对于感光侧的光电二极管,计划按封装(1608 尺寸、20125 尺寸)和光检测单元的尺寸推出4款新机型。
ROHM预计在2023年3月份开始提供应用了该技术的SWIR(发光、感光)样品。ROHM致力于通过为小型应用提供更广泛的物质检测功能,助力新领域感测技术的发展。
开发背景
与近红外(NIR:Near Infrared)相比,SWIR的波长更长,对物质的穿透性更强,因透射或吸收物质不同,不易受阳光和烟雾等微小粒子的影响,这些特点将有望进一步扩大对有机EL显示器、水、气体和葡萄糖等对象物的感测范围。另一方面,目前业内存在的问题是市场上的SWIR产品多为插装型,适用于通信设备、工业分析设备等较大型应用,而适用于小型应用的表贴型产品较少。
ROHM利用在LED等化合物半导体量产过程中积累的生产技术优势,确立了1608封装尺寸业界超小SWIR器件的量产技术。
ROHM短波红外(SWIR)器件详情
ROHM的SWIR器件(发光,感光)计划采用业界超小级别的1.6mm×0.8mm表贴封装。通过小型发光和感光产品的不同组合,不仅可以减少安装面积,从而进一步节省空间,还有助于扩大在小型应用中的感测领域。
・SWIR LED(发光侧)
由于不同物质的检测波长不同,所以发光侧的SWIR LED预计会推出1050nm、1200nm、1300nm、1450nm、1550nm共5种波长的产品,除了常规的模塑型产品外,还将推出两款透镜型(发光指向角更窄、辐射强度更高)表贴封装的产品。届时,通过这些产品的组合预计会推出10款新产品,这将有助于扩大检测范围,在检测水、气体和葡萄糖等物质的有无以及成分分析等应用中发挥重要作用。
・SWIR光电二极管(感光侧)
对于感光侧的SWIR光电二极管而言,存在一些权衡参数,比如光的检测面积小时要求响应速度要快,面积大时要求灵敏度要高。因此,ROHM计划推出两种感光直径和两种封装相组合的共4款新机型。客户可以根据高速响应感测用途和弱光检测用途等不同应用需求进行灵活选择。
目标应用
・通过安装在便携设备等应用中的有机EL显示器进行检测
・可穿戴设备、可听戴设备等健康监测应用
・食品和人体等的含水量检测、药物分析等各种检查设备
术语解说
*1) 短波红外(SWIR:Short Wavelength Infrared)指1000nm~2500nm波段内的光。
