Suppliers Are Already Preparing for the iPhone 18 Camera

Suppliers are already preparing for the production launch of sensors for the new iPhone 18 models. This device is expected to significantly impact the semiconductor supply chain, especially with Samsung Electronics expanding its image sensor production. One of its key testing partners is investing over $120 million in new equipment, reports The Elec.

This week, Doosan Tesna, specializing in post-production semiconductor testing, announced plans to spend $123 million on testing systems from the Japanese company Advantest, a subsidiary of Samsung Semes. The investment represents about 21.77% of the company's total assets and is scheduled to be completed in phases by March 2027. This decision is directly related to Samsung's new sensor production line in Austin, Texas, which is expected to supply components for the iPhone 18 in 2027.

Samsung's resurgence in supplying image sensors for Apple is the first in nearly a decade and could change Sony's dominance, which previously supplied almost all sensors for the iPhone. Reports indicate that Apple has been looking to diversify suppliers due to delays in Sony's shipments in 2023-2024.

Doosan Tesna focuses on electrical wafer testing, allowing for the detection of defective chips before packaging and increasing yield. Over 90% of the company's revenue comes from Samsung's Foundry and System LSI divisions. At the same time, their decision to switch from Teradyne equipment to Advantest is significant, as Advantest systems are widely used for high-performance chips such as GPUs, memory, and AI processors. This indicates that Samsung's new sensors for Apple may require more complex testing and verification processes.

Samsung's production line in Austin is a key element in Apple's strategy to reduce dependence on Japanese suppliers and expand production in the U.S. If Samsung's sensors meet Apple's quality and reliability standards, the company could become the second-largest supplier of image sensors for the iPhone. The substantial financial commitments from Doosan Tesna—over one-fifth of its assets—highlight how preparations for new iPhone models are already reshaping global investments in the semiconductor industry ahead of production commencement.
