自動PC控制和數(shù)據(jù)采集
實時控制所有鍵參數(shù)或全自動配方。所有的鍵合參數(shù),如電流、電壓、集成電荷、溫度、室壓、力、晶圓分離、運行參數(shù)、配方、SPC晶圓批號、事件日志等,都自動存儲在文件中,用于圖形繪制和趨勢分析。機器也可以聯(lián)網(wǎng),并由AML遠程詢問,以幫助發(fā)現(xiàn)故障。全自動配方,包括在生產(chǎn)環(huán)境中自動對齊除霧操作。
對齊方式:
手動和自動對齊。原位對齊比其他焊接(在粘結室外進行對齊)具有優(yōu)勢。'一鍵'對齊和鍵合??梢姽夂图t外光譜。廣泛間隔的三維對齊標記的圖像捕獲。
校準可進行熱或冷:
這消除了由于熱膨脹和晶圓片、機器部件和壓板之間的不匹配而導致的對準誤差。
大晶片分離:
允許晶圓片之間存在較大的溫差,這是通過工藝氣體(如成形氣體)更好地活化或原位氧化還原晶圓片的理想選擇。也允許快速,高真空和良好定義的焊接環(huán)境。
現(xiàn)場系統(tǒng):
還可以在粘接過程之前直觀地確認所需的對齊仍在進行中。
晶片尺寸:
2 ", 3", 4", 5 ", 6 "和8 "。(芯片和形狀奇怪的基板,但沒有對齊)。
機械手:
使晶圓片在真空和高溫下能夠原位對準。
接觸力:通過手動或電動液壓提供,可達40kN。
精密晶圓平行度調(diào)整。
1μm對準精度。
光學:
雙顯微鏡-通過鏡頭照明的照相機系統(tǒng)。兩個CCD相機并排顯示圖像。包括紅外功能。同時顯示晶圓片的分離力和鍵合力,實現(xiàn)對中控制。
成鍵
環(huán)境:
真空,或工藝氣體。全自動干式渦輪泵送系統(tǒng)~ 1x10- 6mbar至2bar壓力。特高壓選項

上下壓板均可獨立調(diào)節(jié),在1°C的步驟。加熱和冷卻速度可編程。溫度是560℃。
電極(陽極鍵合):
全尺寸加熱板,用于上下電極,以獲得更好的粘結均勻性。0-2.5千伏直流可達40毫安。恒流或恒壓運行,改善過程控制和應力管理。
AWB-04可以粘合3到6英寸的晶圓片和芯片

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.
