CESL 1 Etch - 40nm BSI CMOS Image Sensor 40nm

using an etch stop layer architecture allows for accurate patterning by providing a predefined stopping point, thereby preventing damage to delicate underlying interconnect structures [A2].

In the 40nm BSI CMOS Image Sensor flow, the bond pad opening module must establish electrical access to the em…
