Texas Instruments Fabs: Where TI Makes Its Chips
Texas Instruments (TI) operates semiconductor fabrication plants—commonly called "fabs"—that are central to how the company manufactures the chips found in everything from industrial equipment to consumer electronics. Understanding what these facilities are, where they're located, and how they fit into TI's business model can help you grasp the company's role in the semiconductor supply chain.
What Is a Semiconductor Fab? đźŹ
A fabrication plant (fab) is a highly specialized manufacturing facility where raw materials are transformed into finished semiconductor chips. Inside a fab, engineers use photolithography, chemical processes, and precision equipment to etch millions or billions of transistors onto a single piece of silicon. These aren't assembly lines in the traditional sense—they're clean rooms where microscopic contamination can ruin an entire batch of chips.
Building and operating a fab requires enormous capital investment, advanced equipment, and expertise. A single modern fab can cost billions of dollars to construct and requires constant upgrades to remain competitive. Because of these barriers to entry, only a handful of companies worldwide operate their own fabs; many semiconductor companies design chips but outsource manufacturing to specialized foundries.
Texas Instruments' Fab Strategy
Unlike many fabless semiconductor companies that outsource all manufacturing, Texas Instruments owns and operates multiple fabrication plants. This vertical integration—controlling design, manufacturing, and distribution—distinguishes TI from competitors and shapes its business model in several ways.
TI's fabs primarily manufacture analog and embedded processing chips—the types of semiconductors used in power management, signal conversion, microcontrollers, and industrial applications. These products often require older, proven manufacturing processes rather than the cutting-edge nodes (measured in nanometers) that dominate consumer electronics. This focus allows TI to operate fabs using mature technologies where competitors have moved on, giving the company substantial cost advantages on products with stable, long-term demand.
Where TI's Fabs Are Located
Texas Instruments operates fabrication plants in the United States and internationally. The company's fab footprint includes facilities in Texas, California, Oklahoma, and overseas locations. Each fab specializes in particular product lines and process technologies based on its equipment and capabilities.
The specific number and operational status of TI fabs can change over time due to market conditions, technology transitions, and capital allocation decisions. For current details on which fabs are active, their production capacity, and their specializations, Texas Instruments' investor relations materials and annual reports provide the most accurate and up-to-date information.
Why Owning Fabs Matters for TI's Business
Manufacturing control provides several operational advantages:
- Supply chain stability: TI isn't dependent on external foundries' capacity or priorities. During semiconductor shortages, companies with their own fabs often maintain more consistent production than those relying on foundries.
- Cost efficiency on mature products: Older manufacturing processes used for analog and embedded chips have lower per-unit costs when a company owns the facility and has optimized operations over time.
- Product differentiation: TI can invest in manufacturing capabilities tailored to its product portfolio without competing for foundry resources with other customers.
- Long-term product support: TI can continue manufacturing legacy chips in high demand even when they're no longer profitable for pure foundries, important for industrial and automotive customers needing decades of supply.
However, owning fabs also means TI bears the full cost of facility maintenance, equipment upgrades, and workforce management—whether demand is strong or weak.
How Fab Ownership Differs from Foundry Models
The semiconductor industry operates on different business models, each with tradeoffs:
| Model | Companies | Approach | Tradeoff |
|---|---|---|---|
| Integrated Device Manufacturers (IDMs) | Texas Instruments, Intel, Samsung | Design and manufacture their own chips | High capital costs; control over quality and supply |
| Fabless | Qualcomm, NVIDIA, Broadcom | Design only; outsource manufacturing | Lower capital costs; dependent on foundry capacity |
| Pure foundries | TSMC, GlobalFoundries, Samsung Foundry | Manufacture chips designed by other companies | Flexible capacity; serve multiple customers |
Texas Instruments operates as an integrated device manufacturer (IDM), meaning it designs and fabricates. This model suits companies producing high-volume, stable-demand products where manufacturing efficiency compounds over time.
The Economics of Fab Investment
Building a modern fab is a multibillion-dollar undertaking. TI's decision to own fabs reflects a strategic bet that:
- The company's product mix justifies the capital and operational expense
- The company can operate fabs profitably over decades
- Owning capacity provides competitive advantages worth the risk
This isn't true for all semiconductor companies. A company designing cutting-edge processors for AI or smartphones might spend less total capital by outsourcing to TSMC than by building its own fab. But for TI's focus on industrial, automotive, and analog applications with decades-long product lifespans, fab ownership has proven economically viable.
Process Technology and Fab Capabilities
TI's fabs don't compete on the most advanced process nodes. Instead, they operate mature technologies—often 65 nanometers and larger—that are ideal for the analog and power management chips that make up most of TI's revenue. These older processes are:
- More cost-effective at high volumes
- More reliable for industrial and automotive applications where stability matters more than raw performance
- More profitable when a company has operated the same process for years and optimized every step
Occasionally, TI's fabs do use more advanced processes for specific products, but the company generally doesn't compete with TSMC, Samsung, or Intel for bleeding-edge manufacturing capabilities.
How Fab Operations Affect Product Availability
When supply chain disruptions occur—as happened during the COVID-19 pandemic—companies with their own fabs have more control over allocation. TI can prioritize production of its highest-demand products and fulfill committed customers more reliably than companies queuing at external foundries.
However, fab ownership also creates constraints. If demand for a particular product type drops, TI's fabs still have fixed costs. Conversely, if demand spikes, TI can't instantly increase capacity the way a fabless company can by engaging additional foundries.
What This Means for Customers and Investors
For customers buying TI chips: Fab ownership means longer-term product availability and more stable pricing compared to companies dependent on foundry capacity. Industrial and automotive customers often value this stability over the latest performance gains.
For investors in Texas Instruments: Fab ownership means understanding TI's capital expenditure needs, fab utilization rates, and manufacturing margins. These factors are distinct from those of fabless competitors and affect profitability differently across economic cycles.
For those evaluating semiconductor supply chain risk: Companies with diverse supplier relationships—including those with their own fabs—tend to weather supply disruptions better than pure fabless or pure foundry companies.
Texas Instruments' fabs are a cornerstone of the company's integrated business model, enabling reliable manufacturing of analog and embedded processing chips while creating competitive advantages in cost and supply stability. The specific economics, capabilities, and strategic value of these facilities depend on your perspective—whether you're a customer, investor, or simply trying to understand how semiconductor companies operate in different ways.
