Samsung to Manufacture Neuralink Gen 4 Chip on 4nm Process, Replacing TSMC

Samsung is reportedly moving into a new area of advanced chip manufacturing by partnering with Elon Musk’s Neuralink. The collaboration focuses on producing the fourth-generation neural interface chip for the brain-computer interface company. This partnership marks a shift in the supply chain for Neuralink's most critical hardware component.

The new chip will rely on Samsung's 4nm process node to meet specific performance requirements. Unlike newer process technologies, the 4nm node offers better stability for the delicate signals required by neural interfaces. Previous generations of the device used chips manufactured by TSMC, but that relationship appears to be ending.

Neuralink Gen 4 introduces a significant functional change with bidirectional communication capabilities. Earlier versions of the chip could only read data from the brain, limiting their therapeutic applications. The new design allows devices to send signals back into the brain, which could help restore functions like vision.

Samsung has outlined an aggressive timeline for bringing this technology to market. The company aims to ship the first test chips in the first half of 2027. Mass production is scheduled to begin by late 2028, pending successful testing and validation.
