Taiwanese semiconductor giant TSMC is considering collaborating with Elon Musk's Terafab project to establish advanced end-to-end semiconductor manufacturing in the United States. According to an exclusive report from Tim Culpan's Culpium newsletter, later confirmed by Elon Musk on X, the two companies are in discussions about a joint venture to boost American semiconductor manufacturing. The plan involves TSMC potentially developing its own semiconductor manufacturing capabilities, with Terafab providing financial backing, equity participation, purchase agreements, and other necessary steps to keep the new fab capacity operational. As some managers believe that Intel might not come through with its promises, Terafab would need to dual-source expertise.

Previously, we learned that Intel has partnered with Terafab, with Tesla becoming Intel's first major customer for the 14A node at Elon Musk's Terafab AI chip complex in Austin. However, the specifics of this deal remain unclear, including whether Terafab will license the 14A node PDK. While both TSMC and Intel can coexist within the Terafab project, it is important to note that TSMC might not bring its latest semiconductor technology outside of Taiwan, keeping its most advanced nodes at its headquarters, while Terafab remains a secondary project. Perhaps Intel and TSMC will compensate each other where the technology needs balance, but that is yet undetermined.The goal of Terafab is to consolidate the entire chip manufacturing process under one roof. The plant aims to integrate several stages of semiconductor production at a single site, including logic fabrication, memory, packaging, testing, and mask production. This setup is unusual, as these steps are typically spread across multiple specialized facilities and companies.

Additionally, simply investing more funds does not guarantee a solution. Building a competitive fab from scratch requires years of execution, including sourcing parts from companies like ASML, Lam Research, KLA Corporation, and Tokyo Electron. These companies often receive orders years in advance before delivering machinery to TSMC, Samsung, or Intel. Thus, creating a supply chain for equipment, raw materials, and other necessary components will take years to develop. Terafab has reportedly already begun ordering tools for its manufacturing process from these firms, so we can expect the first silicon in a few years.
