Sony Group is set to increase capital expenditure in its semiconductor division, reversing a recent period of investment restraint driven by financial improvement goals.

To manage the substantial costs associated with next-generation process equipment, the company has decided to establish a joint venture with Taiwan Semiconductor Manufacturing Company (TSMC).

This strategic partnership aims to share the financial burden of upgrading production lines for image sensors, which are critical components for Apple's iPhone cameras.

The decision underscores the intense pressure on Sony to maintain its technological edge in image sensor performance for its largest customer, Apple.

While Sony has been tightening investments to improve its balance sheet, the necessity of deploying advanced manufacturing processes to meet Apple's continuous demand for higher camera specifications has forced a strategic pivot.

By partnering with TSMC, Sony can access cutting-edge fabrication capabilities without bearing the full capital load alone.
