Samsung Foundry has reportedly started developing the manufacturing process for Neuralink’s fourth-generation chip, the brain-machine interface company founded by Elon Musk. According to the South Korean financial daily The Korea Economic Daily, Samsung Electronics’ foundry division is working on a version based on its 4-nanometer process and reportedly began pilot production about a month ago.
While not officially confirmed by Samsung or Neuralink, the information suggests mass production could commence by the end of next year. If realized, this would mark the first time Samsung secures a contract from Neuralink—a relatively small-volume client compared to major mobile, automotive, or data center manufacturers—but highly significant given the technology involved and the growing relationship between Samsung and Elon Musk’s business ecosystem.
This move follows Samsung’s strengthened ties with Tesla in the fields of autonomous driving chips and artificial intelligence. For Samsung, adding Neuralink to its client portfolio offers a clear strategic opportunity: demonstrating that their foundry business can compete in advanced designs not only for automotive or generative AI but also for implantable medical devices—where energy efficiency, size, reliability, and safety are critical.
A small but technically demanding chip
Brain-machine interface chips are unlike data center AI accelerators or smartphone SoCs. Their priorities differ. They must detect very weak neural signals, process them with low power consumption, transmit data reliably, and operate within implantable systems that meet strict medical standards.
Currently, Neuralink uses the N1 implant in clinical trials. The company describes this device as a wireless, rechargeable intracortical implant connected to flexible wires with electrodes inserted into the brain via the surgical robot R1. The initial goal is to enable paralytic individuals to control external devices through thought.
| Element | Technical relevance |
|---|---|
| 4 nm process | Enables higher integration and lower power consumption compared to older nodes |
| Brain implant | Requires reliability, miniaturization, and low power use |
| Neural signals | Demand precise readout and noise management |
| Wireless communication | Must transmit data without compromising autonomy or security |
| Medical manufacturing | Requires strict quality controls and validation |
| Samsung Foundry | Offers advanced manufacturing capacity and experience with complex chips |
Moving to a fourth-generation chip could aim to improve several aspects: increased local processing capacity, reduced power consumption, better signal management, more channels, higher integration, or more efficient data transmission. No technical details of the alleged new design have been published, so caution is advised. However, using 4 nm suggests a preference for greater density and efficiency over more mature processes.
In an implantable device, every milliwatt counts. Reduced power consumption can translate into less heat, longer battery life, fewer recharges, and more room for local processing. It could also help in miniaturizing components or integrating functions previously reliant on auxiliary chips.
Why Samsung wants this contract
For Samsung Foundry, Neuralink wouldn’t represent a volume-scale order comparable to chips for mobile devices or automotive systems. Its value lies in technological credibility. Manufacturing a chip for a brain-machine interface requires demonstrating process design expertise, reliability, quality control, and close collaboration with the customer.
Samsung needs case studies to strengthen its position against TSMC, which dominates the advanced foundry market. While Samsung maintains an ambitious roadmap for cutting-edge nodes, its foundry business has had to compete with perceptions that TSMC delivers better yields, higher capacity, and a more established customer base for advanced chips.
| For Samsung | What Neuralink can bring |
| Differentiation | Position as a reference in implantable medical chips |
| Relationship with Elon Musk | Expanding ties beyond Tesla |
| Advanced foundry | Using 4 nm in a unique design |
| Technological image | Presence in neurotechnology and next-generation devices |
| Diversification | Beyond mobile, HPC, and automotive |
| Competition with TSMC | Signal of capacity for demanding clients |
The contract also carries commercial implications. Samsung has been seeking to strengthen its foundry business with high-profile external clients. Tesla is already a key player in this strategy. If Neuralink joins the portfolio, Samsung would expand its exposure to another Musk project, this time in a field closer to biotechnology and implantable computing.
It’s not just about chip manufacturing. In such projects, foundries can participate early in R&D, adjusting process parameters, design rules, power management, and manufacturing requirements. According to Korean sources, Samsung started development late last year and recently moved to testing chips.
Neuralink advances but under regulatory scrutiny
Neuralink has gained visibility since beginning human trials. Its first participant, Noland Arbaugh, demonstrated how the implant could enable computer control via brain signals. The company later acknowledged issues with some wires but stated that software adjustments allowed recovery and performance improvements.
This history highlights the field’s challenges. Brain-machine interfaces combine neurosurgery, electronics, machine learning, software, biocompatible materials, wireless transmission, and medical regulation. A chip that’s fast or efficient isn’t enough; it must be part of a system that is safe, stable, and clinically valuable.
| Critical areas in Neuralink | Challenges |
| Electrodes | Achieving stable neural signal capture |
| Implant | Ensuring safety and biocompatibility |
| Chip | Processing signals with low power consumption |
| Software | Translating neural activity into actionable commands |
| Surgical robot | Precise insertion of wires |
| Regulatory | Meeting clinical and safety requirements |
Potential collaboration with Samsung could support silicon development but wouldn’t eliminate the medical and regulatory hurdles. A next-generation chip could enhance features, but implantable devices require extensive validation, safety testing, and approval before broader use.
Neuralink isn’t the only player in this arena. Companies like Synchron, Blackrock Neurotech, and Precision Neuroscience also work on brain-machine interfaces with different approaches. Some aim for less invasive implants; others focus on higher signal density. Competition will depend on clinical efficacy, safety, ease of implantation, and real patient benefit—not just manufacturing processes.
4 nm for a market not measured in volume
Samsung’s 4 nm process makes sense if Neuralink aims for greater integration and efficiency. In implantable medical electronics, initial volumes may be low, but complexity is high. An advanced foundry offers design, packaging, validation, and manufacturing tools that startups alone could not replicate internally.
Using a cutting-edge node also signals a more ambitious roadmap. If Neuralink seeks to increase channels, improve local processing, or reduce latency, more capable chips will be necessary. Long-term, a useful brain-machine interface for broader applications might need higher bandwidth, embedded algorithms, and more efficient communication between implant and external systems.
Balancing performance with prudence is key. In medical chips, moving to a very advanced node may improve size and power but also introduces validation, cost, and availability challenges. The smallest node isn’t always the best choice, making the apparent use of 4 nm a balanced decision—advanced enough to boost efficiency without the drawbacks of yet newer nodes.
A partnership with a future view
Samsung’s potential entry into Neuralink’s supply chain underscores a broader trend: the boundary between semiconductors, healthcare, AI, and personal devices is tightening. Chips are no longer limited to data center models or vehicle controls—they are increasingly integral to interpreting biological signals and converting them into digital commands.
For Samsung, the appeal lies in positioning itself in a category that could grow significantly over the next decade if brain-machine interfaces demonstrate clinical and commercial value. For Neuralink, access to a global foundry can ensure more stable production and help improve hardware using advanced processes.
The news also reflects how Elon Musk is expanding his industrial relationships. Tesla, xAI, SpaceX, and Neuralink increasingly rely on complex supply chains: chips, memory, packaging, data centers, robotics, communications, and advanced manufacturing. Samsung aims to be involved in several of those layers.
For now, it’s prudent to wait for official confirmation. No public chip details exist yet, and mass production depends on the development progressing as planned. However, if the schedule in Korea holds, Samsung Foundry could begin manufacturing one of Neuralink’s most sensitive components—its silicon—by the end of next year, translating brain activity into digital signals.
