The Stacked CMOS Image Sensor Market Size is rapidly gaining traction, driven by growing demand for high-resolution, compact, and energy-efficient imaging solutions across smartphones, autonomous vehicles, surveillance, industrial automation, and medical devices. Unlike conventional image sensors, stacked CMOS sensors separate the pixel and logic layers into different substrates, allowing for enhanced performance, smaller size, and advanced features like AI processing on-chip.

This architectural advancement has positioned stacked CMOS sensors at the forefront of next-generation imaging technologies, offering faster readouts, better low-light sensitivity, and increased integration flexibility. With the surge in computational photography and machine vision, the Market Size is expected to witness robust double-digit growth over the coming years.

What Is a Stacked CMOS Image Sensor?

A Stacked CMOS (Complementary Metal-Oxide Semiconductor) Image Sensor features a two-layer design:

• Top Layer (Pixel Layer): Dedicated to capturing light and converting it into electronic signals.

• Bottom Layer (Logic Layer): Houses circuitry for signal processing, memory, and other advanced features.

This structure provides:

• Higher pixel density without increasing the chip footprint

• Faster data transfer between pixel and logic layers

• Support for AI, HDR, and multi-frame processing directly on the sensor

• Improved image quality under challenging conditions
