Recently, a collaborative engineering team from Stanford University, Carnegie Mellon University, the University of Pennsylvania, and the Massachusetts Institute of Technology partnered with SkyWater Technology—the largest dedicated semiconductor foundry in the United States—to achieve a groundbreaking milestone: the successful fabrication of the nation's first monolithic 3D chip in a commercial foundry setting.

This innovative chip features a vertically stacked architecture, enabling high-speed, large-scale data transfer through ultra-thin layers and vertical interconnects. It sets a new benchmark for vertical connection density, seamlessly integrating memory and computing units to overcome the traditional "memory wall" and miniaturization limitations of 2D chips.

Through rigorous hardware testing and simulations, the chip has demonstrated performance up to an order of magnitude greater than its 2D counterparts. Early prototypes already showcase a roughly 4X performance boost, with projections indicating that future iterations could deliver up to 12X faster processing for AI workloads. Additionally, the energy efficiency-delay product (EDP)—a key metric for evaluating chip performance—could see improvements ranging from 100X to 1000X.

Manufactured using a streamlined, continuous process, the entire production cycle takes place at domestic commercial silicon wafer fabrication plants in the United States. This achievement marks a pivotal transition of advanced chip architectures from research laboratories to mass production, solidifying the United States' position as a leader in semiconductor innovation.
