CCD image sensors have one foot in the grave

The death of charge-coupled device (CCD) image sensors is certain, according to an imaging and sensors analyst at market research firm Yole Developpement. The opinion article was published by imveurope, and was prompted by a move by the market leader Sony to exit the manufacturing of CCD sensor and camera business.

The expectation is that Sony will discontinue production of CCD sensors at its 200mm wafer line at the Kagoshima Technology Centre in March 2017 with a phase out lasting until 2020.

"The timing might not be yet definitive as discussions are ongoing. One thing is certain: this is the beginning of the end for Sony CCDs," said Pierre Cambou, imaging and sensors analyst at Yole.

Cambou said CCDs still offer the highest performance and for some demanding applications will not be replaced by CMOS image sensors but the companies that have relied on Sony for their CCDs must choose between changing to the remaining CCD suppliers such as Teledyne Dalsa, On Semiconductor (Truesense), e2v, Fairchild Semiconductor or moving CMOS.

Cambou concluded: "It is always sad for technologists to watch the creative destruction of technology shifts. I believe this major transition will renew the innovation drive of the industry. Let's buckle up for a new technology cycle. I am convinced we are not to be disappointed. CCD image sensors are dead, long live CMOS image sensors."
