Nexstrom Raises $12M Seed for 2D Chip Material Technology

Singaporean startup Nexstrom is advancing the frontier of semiconductor manufacturing with its innovative approach to two-dimensional (2D) materials. The company, incubated by Xora Innovation, has successfully raised $12 million in seed funding, bringing its total capital raised to $15 million. This investment, with participation from Xora Innovation, Foothill Ventures, and SEEDS, will fuel the development of equipment and processes designed to integrate advanced 2D materials, specifically transition-metal dichalcogenides (TMDs), into mainstream chip fabrication lines.

The semiconductor industry has long pursued miniaturization by shrinking silicon transistors, a path fraught with challenges like electron leakage and increased power consumption. Nexstrom aims to circumvent these limitations by leveraging the unique properties of atomically thin TMDs. These materials, mere layers thick, offer a compelling alternative for creating smaller, more efficient transistors. The company's flagship product, North Star, is engineered to enable the direct growth of these TMDs on standard 300mm wafers, a critical step for compatibility with existing foundry infrastructure.

The potential of 2D materials in next-generation electronics is widely recognized, with industry titans such as TSMC, Intel, and research consortium IMEC actively exploring their integration. Companies like AIXTRON and CDimension are also developing complementary manufacturing solutions. However, Nexstrom is focusing on a particularly demanding aspect: achieving high-quality, large-scale production of these novel materials. This focus aligns with the expertise of co-founder and chief scientist Lance Li, who brings extensive research experience in post-silicon electronics and 2D materials from his tenure at TSMC.

“Bridging the gap between laboratory-scale material synthesis and industrial-volume production is our core mission,” stated Lance Li. “While lab environments can yield exceptional material quality, scaling this to commercial levels presents significant hurdles that Nexstrom is designed to overcome.” The company’s strategy involves collaborating with, rather than directly competing against, established chip manufacturers like TSMC, Samsung, and Intel, positioning itself as a key technology provider.

Nexstrom's CEO, Phoebe Tan, emphasized the company's progress in meeting stringent industry standards. “Our current efforts are concentrated on delivering material quality that meets the precise specifications of our industry partners,” she explained. “We have successfully demonstrated material performance on 12-inch wafers using our newly installed system, having systematically scaled from 2-inch to 6-inch prototypes. We anticipate completing our 8-inch and 12-inch system validations by the end of October.”

The newly secured seed capital will be instrumental in advancing Nexstrom's technological development, moving its equipment closer to commercial readiness. Funds will also support enhancements in process control and measurement capabilities, team expansion, and the crucial qualification programs with prospective clients. The company projects its manufacturing equipment to be market-ready between 2030 and 2035, a timeline that reflects the significant engineering and validation required for introducing novel materials into the highly regulated semiconductor supply chain.
