亿毫安电子红外线感测器应用手册说明书

——反射式光中断器——物体侦测应用手册一、简介随着科技进步,各种电子产品自动化程度也跟着提高自动化程度越高的产品,代表也包含了更多的感测元件。
为了避免人眼被环境中各种产品或设备感测时发射的光干扰,所以使用人眼无法察觉的红外线(Infrared;IR)产品做为感测器。
这份应用手册将会介绍如何利用红外线发射元件(Infrared Emitter)及红外线接收元件(Infrared Receiver)作物体侦测应用。
最常见的红外线发射及接收元件就是红外线发光二极管(IR Light-emitting diode;IR LED)及光电晶体管(Photo Transistor;PT),图一为基本的IR LED搭配PT的应用电路。
图一、IR LED及PT基本应用电路原理说明:IR LED为发射端,顺向电流(Forward current;IF)越大发射的辐射强度越大调整R limit值可控制IF的大小Vout可接MCU的ADC(Analog-to-Digital Converter)或GPIO做准位判断判断说明:无辐照度时,PT截止,Vout输出为高电位(Vcc)辐照度低时,PT导通,Vout输出为高电位(Vcc–(Ic x RL))辐照度高时,PT饱和,Vout输出为低电位(VCE(sat))注:V CE(sat)为PT饱和电压。
二、利用反射式ITR做物体侦测方法IR LED通常和PT一起搭配作为物体侦测或是遮断侦测应用图二为利用IR LED发射IR经由物体反射到PT做反射式物体侦测的示意图;为了避免IR LED发射的IR不经过物体反射,直接在机构内照射到PT造成误判,所以IR LED跟PT 必须有效隔离。
利用底下的两项特性,即可做到反射物的距离侦测。
反射物距离越近,PT收到的反射辐照度越强,输出的电流会越高。
不同的材料会有不同的反射率,一般颜色越深、表面越粗糙的物体反射率越低,同距离情况下,接收端输出的电流相对会降低。

图1 检测系统结构图
对于理想晶体来说,光是否透射晶体取决于光子的能量和晶体材料的禁带宽度: g E hc />λ
对于硅的禁带宽度为1.12eV ,故其透射光最小波长为1.1μm 。
如果两片晶圆的键合界面存在未键合区域,则入射光在上下表面两次反射后形成相干光,经红外摄像机处理后,会在显示器上出现明暗交替的干涉条纹。
如果未键合区域面积较大且间隙高度不大,则会出现很多较大的干涉条纹;当键合界面处间隙较大时,入射光无法形成干涉现象,在图片上的对应位置将只能出现颜色较暗的图案。
因此,根据键合片的红外透射图像,就可以检测到键合圆片的缺陷状态及分布。
根据干涉的圈数还可以定量的计算出空洞的大小。
产生暗条纹,应满足:
λλ21212+=m nd ),2,1,0( =m
其中n 为空洞中介质的折射率,d 为空洞高度,m 为干涉环数,λ为所用红外光的波长。
若已知n 、m 、λ,则可得:
n n m d 44λλ+= ),2,1,0( =m
图2 未键合区域光线反射图图3 红外透射干涉图
检测系统主要有四个部分:光源部分、工作台部分、红外相机部分和计算机部分。
测试系统的结构如图1所示,主要部分包括:底座、盒体、白炽灯、匀光片、待检测圆片、滤光片、放大镜头和红外摄像机。
不同尺寸的晶圆成像距离不同,镜头和晶圆间距离的调节可以通过改变横梁的高度和改变摄像机的焦距来实现。
盒体设计如图4所示。
采用4光源,以获得较为均匀一致的光强分布,避免不均匀光强对观测结果的影响。
为了获得较高对比度的图像和适应不同尺寸晶圆的成像,通常需要调节功率调节器以使照明系统提供的光强可控制。
低光强的图像对比度较高,而高光强的图像分辨率更高。
