This report presents a device essentials folder (DEF) of the SK Hynix Hi-1631Q 16 MP resolution 1.0 μm pixel pitch CMOS image sensor. The SK Hynix Hi-1631Q is a 16 MP stacked back-illuminated CMOS image sensor featuring 1.0 µm generation pixels and Quad Bayer color filter array. It is the first documented use of chip stacking by SK Hynix for an image sensor.
The DEF includes observed device metrics and salient features supported by the following unannotated image folders:

• Downstream product teardown
• Package X-rays, die photograph, non-invasive optical photos of die features
• SEM images of the pixel array delayered to the metal, transistor, and diffusion levels
• Exploratory cross-section SEM imaging of the general pixel array and peripheral structures

This deliverable provides basic competitive benchmarking information and enables cost-effective tracking of multiple competitors’ technology.
