TSMC to Begin Small Scale Run in Arizona Amid Full Production Delay

TSMC, the world's largest contract chipmaker, has announced that it will begin pilot production at its new plant in Arizona in 2024. The full production of the plant was supposed to start in 2025, but it has been delayed due to a worker shortage. The pilot production will help TSMC to train workers and test the equipment at the plant.


Taiwan Semiconductor Manufacturing Company (TSMC) has long been a key player in the semiconductor manufacturing industry, producing chips for some of the world’s leading technology companies. In recent years, TSMC has been expanding its operations globally, with a significant focus on the Arizona, United States.

One of the notable developments in this expansion was the construction of Fab 21 in Arizona. However, recent news has revealed a delay in its mass production until 2025 due to alleged workforce shortages in the state.

To address this challenge and ensure consistency in chip supply, TSMC has decided to establish a small-scale pilot production line, set to commence operations in 2024. In this blog post, we will delve into the details of this strategic move by TSMC and its implications for the semiconductor industry.

The Arizona Fab 21 Project

TSMC initiated the construction of Fab 21 in April 2021 with the aim of commencing chip production by early 2024. This was a significant step in TSMC’s commitment to establishing a strong presence in the United States, addressing both political and logistical considerations.The Fab 21 facility in TSMC Arizona is playing a crucial role in producing advanced semiconductor chips for various clients, including tech giants like Apple, AMD, and Nvidia.

However, as with any large-scale construction project, challenges arose. Equipment move-in delays pushed the start date for mass production to 2025, which raised concerns about meeting contractual obligations and maintaining a steady chip supply to clients, especially those with agreements requiring domestic production.

The Pilot Production Line Solution

To mitigate potential breaches of contracts and ensure a consistent chip supply, TSMC decided to take a strategic shift. Consequently, they are establishing a small-scale pilot production line. This pilot line is expected to be operational by the first quarter of 2024. It will have a monthly production capacity ranging from 4,000 to 5,000 wafer starts per month. While this may seem relatively modest compared to the total capacity of Fab 21 (about 20,000 wafer starts per month), it’s a significant move with several important implications.

Contractual Compliance

The delay in Fab 21’s mass production could have potentially breached agreements with clients like Apple, AMD, and Nvidia, who may have commitments to produce certain products in the USA. The pilot production line will help TSMC Arizona meet these contractual requirements and maintain strong partnerships with its clients.

Consistent Chip Supply: With a pilot production line in place, TSMC can ensure a steady supply of chips to its American clients even before Fab 21’s mass production begins. This is crucial given the high demand for semiconductor chips across various industries.

Risk Mitigation: By having a small-scale production capability, TSMC can test and refine its processes, identify potential issues, and gradually ramp up production to meet the eventual demand when Fab 21 reaches full capacity in 2025. This approach reduces the risk of encountering production challenges on a larger scale.

Optimism for the American Endeavor: Despite the delay in mass production, TSMC remains optimistic about its American endeavor. The establishment of the pilot production line demonstrates the company’s commitment to its American clients and its ability to adapt to challenges in a rapidly evolving industry.


TSMC’s decision to establish a small-scale pilot production line in Arizona reflects its dedication to maintaining strong relationships with its American clients and addressing the challenges posed by the delay in Fab 21’s mass production.

This strategic move not only ensures contractual compliance but also contributes to the overall stability of semiconductor chip supply in the United States.

As the semiconductor industry continues to play a pivotal role in technological advancement, TSMC’s efforts in Arizona underscore the importance of adaptability and resilience in the face of unforeseen obstacles.
