Sony is preparing to work more closely with TSMC in the production of image sensors used in smartphone cameras. The company’s semiconductor unit, Sony Semiconductor Solutions, will form a new joint venture with Taiwan Semiconductor Manufacturing Company (TSMC) to produce image sensors. In the planned structure, control will remain with Sony and the Japanese company will be the sole controlling shareholder of the joint venture. While mass production is aimed to start in 2029, the two companies will bring together their different expertise in production and technology development under the same structure. However, in order for the joint venture to become operational, various financial and administrative processes, including evaluations of regulatory institutions, must be completed.
Sony Semiconductor Solutions will contribute a total of 465 billion yen in cash and assets to the company. The announced figure corresponds to approximately 2.92 billion dollars or 2.6 billion euros. TSMC’s contribution will be 282 billion yen, or approximately 1.77 billion dollars or 1.5 billion euros. The investment amounts also reveal why Sony will have a controlling position in the joint venture. Despite this, TSMC’s role will not be limited to financial contribution only, and the Taiwanese manufacturer’s advanced semiconductor production processes will be one of the key elements of the new structure.
Sony and TSMC to combine expertise in image sensor manufacturing
The division of duties between the two companies gives a clearer picture of how the joint venture will work. Sony will manage the development, product planning and design processes of the core technologies of image sensors. TSMC will transfer its experience in advanced production processes to the project. Thus, the talents of Sony, which has long had a strong position in sensor design, and TSMC, one of the world’s leading companies in advanced production technologies, will meet in the same production chain. This structure can benefit from the two companies’ experiences in different fields, especially in terms of the production of more complex sensors that offer higher performance in smartphone cameras.
Sony has long been a major supplier to smartphone manufacturers in the CMOS image sensors market. The company’s sensors are used not only in its own Xperia phones, but also in upper and mid-range models from different manufacturers. The increasing complexity of camera systems in mobile devices makes it no longer sufficient to simply increase the resolution on the sensor side. Faster data reading, low light performance, dynamic range, energy consumption and processing capabilities on the sensor are among the main areas that manufacturers are working on. Access to more advanced manufacturing processes could therefore give Sony more leeway in terms of physical size and power efficiency, as well as the performance of future sensors.
On the TSMC side, the agreement will allow the company’s advanced production technologies to be used more comprehensively in the field of imaging. The Taiwan-based company has a wide customer portfolio in the production of chips that require high performance, such as smartphone processors, graphics processors and artificial intelligence accelerators. Although image sensors have different manufacturing needs than classical processors, it is becoming increasingly common for image capture layers to work together with advanced logic circuits in modern sensor designs. TSMC’s experience in advanced process technologies can provide an advantage at this point, especially in the image processing and control circuits of the sensor. However, details regarding which production technologies the joint venture will specifically use or which sensor families it will focus on in the first stage have not yet been announced.
The mass production target, set as 2029, also shows that the project is not a development that will replace existing smartphone cameras in the short term. In the next few years, the joint venture will need to obtain the necessary approvals, its financial structure will be completed and the production infrastructure will be prepared. In addition, competition in the image sensor market and camera preferences of smartphone manufacturers will continue to change during this period. Leveraging TSMC’s manufacturing technologies while maintaining Sony’s control over sensor development and product design creates a model that will allow the company to keep its technical competencies in-house. On the other hand, the fact that production will not start until 2029 and the regulatory processes have not yet been completed shows that we have a long calendar ahead of us to evaluate the real impact of the partnership.
