Sony Group recently announced it is forming a co-development partnership with chip manufacturing giant Taiwan Semiconductor Manufacturing Company (TSMC) to create what it calls the next generation of AI image sensors. In announcing the partnership, the company revealed that, with these next-level AI sensors, it is targeting the advanced robotics and automotive segments.
Learn all about Sony’s next great technological foray…
Sony Semiconductor Solutions and TSMC have signed a nonbinding memorandum of understanding (MoU) as the preliminary step in creating a co-development joint venture to design, develop, and manufacture next-gen AI image sensors, according to a report by the Nikkei. While there are many elements of this MoU still to be worked out, we do know that Sony will hold a majority stake in the venture. We also know that the partners will build development and production lines at Sony’s new chip factory in Kumamoto prefecture in southwestern Japan.
Sony is already a global leader in image sensors that are widely used in smartphones, automotive, and industrial applications. Meanwhile, TSMC is a world-leading semiconductor foundry, manufacturing mid-level and high-end semiconductor chips of all types.
Why Would Sony Outsource Chip Manufacturing?
You might ask why, if Sony owns its own chip fabrication plants, it would want to partner with TSMC to manufacture its chips. That is a big and important question. In a press briefing with the industry press in Japan to discuss its corporate strategy, Sony Group CEO Hiroki Totoki told reporters that this new agreement with TSMC was the first step in the company moving to what is known as a “fab-light” business model. This means the company is shifting its business towards working on a contract basis with outsourced chip manufacturers, rather than building out its own chip fabrication business.
A great example of this is Nvidia, which contracts with TSMC to manufacture its graphics and AI chips, rather than expending the exorbitant amount of money it would take to build multiple company-owned chip fabrication production facilities around the world. This model works and can improve profits for companies like Nvidia and Sony.
Sony Moves to Fab-Light Model for Faster Scaling & Greater Profitability
In the past, Sony, like other chip manufacturers, was a fully integrated device manufacturer. That means Sony itself was responsible for researching, developing, designing, testing, reworking, testing again, and manufacturing all of its various devices. Now, according to CEO Totoki, going forward, Sony wants to work more closely with external manufacturers.
This strategy, the company told reporters, will improve Sony’s scalability as demand for sensors expands beyond smartphones into what Totoki called “physical AI” – meaning robotics and autonomous systems. TSMC owns a 70% share of the global semiconductor foundry market and produces over 90% of the world’s most advanced microchips. By partnering with the largest chip foundry in the world, scaling to meet increased demand should be no issue for Sony as it begins selling more and more of their new, more advanced image sensors.
Japan Government Strategy to Build Up Domestic Chip Manufacturing Capabilities
“Until now, image sensor supply has been constrained by the capacity of our own fabs,” Totoki told journalists. He added that this partnership would help strengthen Sony’s position as the global leader in image sensors.
The news of this joint venture comes as Japan is going through a time of great investment in its chip manufacturing infrastructure. The government is approaching this goal through a series of public/private investments. For example, the new plant Sony is building in Koshi in the Kumamoto prefecture received 60 billion yen (approximately $380 million) in subsidies from the Japanese government. The government has also offered similar subsidies for TSMC, which has also expanded its facilities in the region.
Now, for this joint venture, the two partners say that their combined investments into the JV would likely be implemented in phases, based on both market demand and level of government support.
Sony Predicts Double-Digit Profit Improvement
In its discussions with the media, Sony suggested that its full-year profits will grow by more than 10% this year. This was a bit of a surprising boast, considering how the company, like all electronics makers, is struggling with increasing memory chip pricing. However, the company appeared confident, with Sony CFO Lin Tao saying she believed that Sony could limit the impact of “soaring” memory chip prices on its 2026 outlook to around 30 billion yen through careful planning and strategies in procurement, design, and sales efforts.
Then, the Nikkei report confirmed something I’ve been warning Strata-gee readers about for years.
The Nikkei Points Out Sony is Transitioning Away from Hardware to Software
The upbeat profits forecast comes as Sony pushes ahead with a broader shift toward entertainment and content, moving further away from its roots as a consumer electronics maker amid intensifying pressure on hardwware products. [Emphasis added]
Nikkei report: Sony and TSMC partner on next-generation image sensors
For the last few years, Sony has been shifting its focus away from hardware-centric businesses to more software-based ones, such as gaming, films, music, and streaming services. The company believes this will build a more stable earnings base with recurring content revenue. We saw a very visible and dramatic example of the execution of this plan to change its business model in April of this year. As I reported to Strata-gee readers at that time, Sony sold its video & audio business to TCL, a large Chinese conglomerate. Sony retains a piece of the ownership equity, but TCL holds the majority of the equity of that business and, hence, is its owner.
Company Already Feeling the Benefits of Its Business Model Change
Sony believes it is already benefiting from this change of strategy. For the Fiscal year ended this past March, the company posted a net profit of 1.03 trillion yen, down 3.4% from the previous year, partly due to a 44.9 billion yen equity-method investment loss tied to the discontinuation of its joint venture with Honda on the Afeela EV. However, operating profit rose 13.4% to 1.44 trillion yen, and sales increased 3.7% to 12.47 trillion yen.
