Toray Develops Ultra-Thin Semiconductor Material to Power AI Era, Mass Production Targeted for 2028 + Video

🔥 A New Material at the Center of the AI Semiconductor Race

As artificial intelligence pushes semiconductor technology to its physical limits, material innovation is becoming just as critical as chip design itself. Toray Industries has entered this race with a newly developed material designed for ultra-thin semiconductor manufacturing, aiming to support next-generation AI chips that demand higher speed, greater memory density, and advanced stacking technologies. The company plans to begin mass production by 2028, positioning the material as a foundational component for future AI-driven hardware.

📌 the Original Report: Toray’s Ultra-Thin Semiconductor Breakthrough

Toray announced the development of a new material specifically designed for manufacturing ultra-thin semiconductor chips with thicknesses as low as 30 micrometers or less. This innovation targets the rapidly growing demand for AI-related semiconductors, particularly high-performance memory components that require extreme thinness to enable multi-layer stacking. By suppressing material deformation during the wafer thinning process, the new material allows wafers to be shaved down evenly, achieving a near-uniform thickness across the entire chip surface.

The core of the new material is based on high heat-resistant polyimide resin. In advanced AI semiconductors, especially those using high-bandwidth memory (HBM), increasing the number of stacked memory layers is essential for faster data processing. However, thinning wafers for stacking often leads to deformation under pressure. Toray’s material addresses this issue by offering more than twice the deformation resistance of conventional materials, ensuring that pressure is evenly distributed during wafer grinding. This results in thinner, more consistent chips that enhance overall semiconductor performance.

Beyond HBM, the material is expected to be applicable to NAND flash memory used in solid-state drives (SSDs), as well as power semiconductors for electric vehicles and other high-power applications. Importantly, Toray confirmed that the material does not use PFAS or other potentially harmful fluorinated compounds, aligning with increasing global environmental and health regulations. For production, the company plans to utilize existing manufacturing infrastructure, reducing capital expenditure and accelerating commercialization toward its 2028 target.

🧠 What Undercode Say:

Toray’s announcement may appear incremental at first glance, but it represents a strategically significant shift in how semiconductor performance gains will be achieved in the AI era. As transistor scaling slows and chip architectures become increasingly three-dimensional, materials that enable precision, stability, and uniformity are becoming silent enablers of progress. Ultra-thin wafers are no longer a niche requirement; they are central to AI memory scaling, advanced packaging, and heterogeneous integration.

The emphasis on deformation resistance is particularly telling. In high-bandwidth memory, even microscopic inconsistencies in thickness can lead to yield losses, thermal inefficiencies, or reliability issues once chips are stacked. By doubling resistance to deformation, Toray is not just improving manufacturability, it is indirectly improving performance-per-watt, thermal stability, and long-term durability of AI systems.

Another key insight lies in Toray’s material choice. Polyimide has long been used in semiconductor processes, but optimizing it for extreme thinness without sacrificing thermal resistance is non-trivial. This suggests Toray is leveraging deep materials science expertise rather than chasing short-term trends. The decision to avoid PFAS is equally strategic. Regulatory pressure on fluorinated compounds is intensifying worldwide, and semiconductor supply chains are being forced to rethink long-standing chemical dependencies. Toray’s PFAS-free approach future-proofs the material against regulatory disruption.

Equally important is the reuse of existing production infrastructure. This signals that Toray understands the cost sensitivity of semiconductor manufacturing, especially as fabs already struggle with rising equipment and energy expenses. Materials that require minimal process changes are far more likely to achieve adoption at scale.

From a broader industry perspective, this development underscores a shift in competitive advantage. The next leap in AI hardware performance will not come solely from chip designers or foundries, but from upstream material suppliers capable of solving physical constraints that silicon alone cannot overcome. Toray’s move positions it not just as a materials vendor, but as a strategic partner in the AI semiconductor ecosystem.
