According to the source, SK Hynix has started mass production of image sensors with a pixel pitch of 0.7 microns, competing in the global image sensor market with Sony and Samsung Electronics. It recently launched these 50MP image sensors, which are on par with similar Sony products.
The source explains that the pixel size of the image sensor determines the size of the entire camera module. If the pixels are small, the size of the lens protruding from the back of the smartphone can be reduced.
In June 2021, Samsung Electronics launched the industry’s smallest 50MP image sensor with 0.64μm pixels, and in September of the same year introduced a 200MP image sensor with the same pixels. At CES 2022, Omnivision unveiled an image sensor with 0.62µm pixels.
In the image sensor market, Sony ranks first with a 40% share, followed by Samsung with a 20% share.
SK Hynic is expected to supply new sensors to Samsung Electronics. It is possible that they will be used in Galaxy A series smartphones, which are scheduled for release in the second half of the year. Previously, SK Hynix supplied 13MP image sensors with 1.0µm pixels for the Samsung Galaxy Z Flip 3 foldable smartphone.
