This is a massive, multi-fab "mega-site" under construction. Announced in November 2021, the Sherman site has the potential for four connected 300mm fabs (SM1, SM2, SM3, SM4).
SM1 is slated to begin initial production in 2025.
Construction on the exterior shell of SM2 is already complete.
SM3 and SM4 are planned for future demand, demonstrating TI's long-term vision. This represents an investment of up to $40 billion in this single location.
Dallas, Texas (DMOS5, DMOS6, DFAB):
While more details on their 300mm plans are often highlighted, TI has existing fabs in Dallas, including DMOS5 (200mm wafers) and DMOS6 (300mm wafers). DFAB is another older facility, likely on 150mm or 200mm wafers. These fabs contribute to their analog and DLP product lines.
Sub-heading 2.2: Expanding West - Fabs in the Mountain West
TI is also expanding its footprint outside of Texas to enhance its domestic manufacturing capabilities.
Lehi, Utah (LFAB1 & LFAB2):
LFAB1 was purchased by TI in 2021 and began 300mm wafer production in 2022.
LFAB2, a second 300mm semiconductor wafer fab, is currently under construction on the same site and will connect to LFAB1. This investment in Lehi is significant, estimated at $11 billion for LFAB2 alone. At full production, these two fabs in Utah will also manufacture tens of millions of analog and embedded processing chips daily.
Sub-heading 2.3: International Footprint (Wafer Fabs)
While the recent focus has been on significant U.S. expansion, TI also has established international wafer fabrication presence.
