自动PC控制和数据采集
实时控制所有键参数或全自动配方。所有的键合参数，如电流、电压、集成电荷、温度、室压、力、晶圆分离、运行参数、配方、SPC晶圆批号、事件日志等，都自动存储在文件中，用于图形绘制和趋势分析。机器也可以联网，并由AML远程询问，以帮助发现故障。全自动配方，包括在生产环境中自动对齐除雾操作。
对齐方式:
手动和自动对齐。原位对齐比其他焊接(在粘结室外进行对齐)具有优势。'一键'对齐和键合。可见光和红外光谱。广泛间隔的三维对齐标记的图像捕获。
校准可进行热或冷:
这消除了由于热膨胀和晶圆片、机器部件和压板之间的不匹配而导致的对准误差。
大晶片分离:
允许晶圆片之间存在较大的温差，这是通过工艺气体(如成形气体)更好地活化或原位氧化还原晶圆片的理想选择。也允许快速，高真空和良好定义的焊接环境。
现场系统:
还可以在粘接过程之前直观地确认所需的对齐仍在进行中。
晶片尺寸:
2 "， 3"， 4"， 5 "， 6 "和8 "。(芯片和形状奇怪的基板，但没有对齐)。
机械手:
使晶圆片在真空和高温下能够原位对准。
接触力:通过手动或电动液压提供，最大可达40kN。
精密晶圆平行度调整。
1μm对准精度。
光学:
双显微镜-通过镜头照明的照相机系统。两个CCD相机并排显示图像。包括红外功能。同时显示晶圆片的分离力和键合力，实现对中控制。
成键
环境:
真空，或工艺气体。全自动干式涡轮泵送系统~ 1x10- 6mbar至2bar绝对压力。特高压选项
温度:
上下压板均可独立调节，在1°C的步骤。加热和冷却速度可编程。最高温度是560℃。
电极(阳极键合):
全尺寸加热板，用于上下电极，以获得更好的粘结均匀性。0-2.5千伏直流可达40毫安。恒流或恒压运行，改善过程控制和应力管理。
AWB-04可以粘合3到6英寸的晶圆片和芯片
AWB-08可以粘合6英寸和8英寸的晶片

Automatic PC Control & Data acquisition
Live control of all bond parameters or fully automated recipes. All the bonding parameters e.g. current, voltage, integrated charge, temperature, chamber pressure, force, wafer separation, run parameters, recipes, wafer batch No for SPC and event logs are automatically stored in files for graph plotting and trend analysis. Machines can also be networked and remotely interrogated by AML to aid fault finding. Fully automatic recipe, including auto alignment to deskill operation in a production environment.
Alignment:
Manual and auto alignment. In-situ alignment has advantages over other bonders (where alignment is made outside the bond chamber).‘One click’ align and bond. Visible and IR. Image capture for widely spaced 3D alignment marks.
Alignment can be carried out hot or cold:
This eliminates alignment inaccuracies due to thermal expansion & mismatch between wafers, machine parts & platens.
Large wafer separation:
Allows large temperature difference between wafers – ideal for better activation or in-situ oxide reduction via process gas e.g. forming gas. Also allows fast, high vacuum & well defined bonding environment.
In-situ system:
Also enables visual confirmation just before the bonding process that the desired alignment is still being achieved.
Wafer sizes:
2”, 3", 4", 5”, 6” & 8”. (Also chips & odd shaped substrates, but without alignment).
Manipulator:
Enables in-situ alignment of wafers under vacuum and at elevated temperature.
Contact force: up to 40kN provided via manual or motorised hydraulics.
Precise wafer parallelism adjustment.
Alignment accuracy 1 μm.
Optics:
Twin Microscope – camera system with throughthe-lens illumination. Two CCD cameras and side-by-side display of images. Including IR capability. Simultaneous display of wafer separation & bonding force for complete alignment control.
Bonding
Environment:
Vacuum, or process gas. Fully automated dry turbo pumping system ~ 1x10-6 mbar to 2bar absolute pressure. UHV option
Temperature:
Both Upper & Lower Platens independently adjustable in 1 °C steps. Heating & Cooling rates are programmable. Max Temperature is 560°C.
Electrodes:(for Anodic Bonding)
Full size heated platens for both upper andlower electrodes for better bond uniformity. 0-2.5 kV DC up to 40 mA. Constant current or voltage operation, for improved process control & stress management.
