    • The present invention relates to a technology related to fabrication of a next generation image sensor, and more particularly to a method of fabricating a next generation CMOS image sensor through which wafer-level package (WLP) performance of an image sensor can be improved through a low temperature process at 300 °C or lower. The present invention provides a method of fabricating a next generation CMOS image sensor for performing a WLP process by manufacturing a sensor unit and applying a TSV technology, wherein a non-electrolytic gold NiB thin film is deposited on an aluminum pad exposed through a via hole formed through the TSV technology, an insulating film on a side surface of the via hole, and a hard mask at an upper portion of a wafer of the CMOS image sensor.
    • 本发明涉及一种与下一代图像传感器的制造相关的技术,更具体地涉及一种制造下一代CMOS图像传感器的方法,通过该方法可以通过图像传感器的晶片级封装(WLP)性能来提高图像传感器的性能 在300℃以下的低温处理。 本发明提供一种制造下一代CMOS图像传感器的方法,用于通过制造传感器单元并施加TSV技术来执行WLP处理,其中非电解金NiB薄膜沉积在通过通孔暴露的铝焊盘上 通过TSV技术形成,在通孔的侧面上具有绝缘膜,以及在CMOS图像传感器的晶片的上部的硬掩模。
