2.2 Process Platforms and Process Technologies
2.2.1 Mainstream Process Node Analysis
The process technology of image sensors is evolving towards more advanced nodes and higher integration. The mainstream process nodes include 40nm, 28nm, 22nm and more advanced processes.
40nm process is one of the most widely used nodes, with many mid-to-high-end sensors still utilizing this process. For example, Sony’s IMX803 still adopts the 40nm process, mainly for cost and power consumption balance considerations.(95) The 40nm process has advantages of maturity, stability, high yield, and moderate cost in sensor applications.
28nm process is becoming the mainstream choice for high-end sensors. TSMC’s 28nm CIS process supports stacked architecture, achieving higher integration and better performance.(78) OmniVision’s 0.56μm pixel technology is based on TSMC’s 28nm CIS dedicated process node. The 28nm process has significant improvements in power consumption, performance, and integration compared to the 40nm process.
22nm and more advanced process nodes are mainly used for high-end applications. TSMC’s 22nm process supports high-performance logic circuit integration, suitable for manufacturing intelligent sensors with AI processing capabilities. In stacked sensors, the analog circuit part usually adopts the 28nm process, while the digital circuit part can use the 22nm or more advanced processes.
2.2.2 Special Process Technologies
In addition to standard CMOS processes, image sensors also adopt various special process technologies to enhance performance.
Back-illuminated (BSI) technology is one of the mainstream technology routes. Compared to traditional front-illuminated (FSI), BSI places the photodiode above the metal interconnect layer, reducing the path for light to reach the photodiode, thus improving quantum efficiency, especially in low-light environments. Major manufacturers such as Sony, Samsung, and OmniVision widely adopt BSI technology.
Stacked CMOS technology further enhances the integration and performance of sensors. By manufacturing different functional layers (such as photodiode layer, pixel transistor layer, logic circuit layer) on different wafers and then connecting them through TSV (Through-Silicon Via) technology, more functions can be integrated within a limited chip area.(96) This technology is particularly suitable for high-end sensors that require integration of ISP (Image Signal Processor), DRAM, and other functions.
Special pixel structure technologies are also continuously innovating. For example, Sony’s dual-layer transistor pixel technology achieves higher full well capacity and better dynamic range by integrating two transistors within the pixel.(96) Samsung’s ISOCELL technology reduces crosstalk between pixels through physical isolation, improving image quality.
