According to reports, Apple's upcoming iPhone 18 Pro series will incorporate some CMOS Image Sensors (CIS) manufactured at Samsung's Austin wafer fabrication plant in the United States. This move signifies a potentially significant transformation in Apple's CIS chip supply chain. Samsung is currently building a new production line at its Austin facility and has already positioned the necessary equipment and engineering staff. In early December, Samsung unveiled a $19 billion investment plan aimed at the acquisition, repair, and upkeep of cutting-edge semiconductor equipment. This investment is intricately linked to its fresh agreement to supply CIS chips to Apple. The new CIS production line is anticipated to kick off operations as early as March 2026, with initial applications likely limited to the iPhone 18 Pro and Pro Max models.

The CIS chips demanded by Apple are projected to leverage Samsung's advanced three-layer wafer stacking technology. This technology boosts image data processing speed and elevates picture quality through hybrid bonding techniques. Historically, iPhone camera CIS chips have been predominantly sourced from Sony, with the majority of production lines situated in Japan. This strategic shift indicates that Apple may be diversifying its CIS chip supply sources and geographical distribution, moving away from heavy reliance on a single supplier and region.
