Key Points:
- TSMC plans to open a massive new chip packaging plant in Arizona by 2029.
- The company needs to expand packaging capabilities to solve a massive supply bottleneck for modern AI chips.
- Construction on the new Arizona facility is already underway, bringing advanced CoWoS and 3D-IC capabilities to the United States.
- TSMC is currently working with Amkor Technology to accelerate US-based manufacturing options for massive customers like Apple and Nvidia.
Taiwan Semiconductor Manufacturing Co. (TSMC) is bringing a massive piece of its supply chain directly to the United States. A top executive at the massive chipmaker recently confirmed that the company plans to open a brand-new, highly advanced chip-packaging plant in Arizona by 2029. This massive expansion will help address a critical bottleneck in the global technology supply chain and ensure American tech giants are supplied with the hardware they desperately need.
The move addresses a very specific problem in the modern tech world. Modern artificial intelligence chips, like the incredibly popular ones designed by Nvidia, are no longer just single pieces of silicon. Instead, engineers build these modern marvels by gluing several different chips together using highly advanced packaging technologies. This specific packaging step has recently become a massive supply bottleneck, severely slowing down production for Nvidia and dozens of other top-tier hardware companies.
TSMC first hinted at this massive expansion earlier this year. During a January earnings call, the company told investors that it was actively applying for the necessary local permits to begin construction. The plan called for building the company’s first advanced packaging plant directly inside its massive existing Arizona facility. However, executives refused to provide a firm timeline for when the new plant would come online and start producing chips.
The timeline finally became clear this week. During a major technology conference held in Santa Clara, California, on Wednesday, TSMC executives proudly confirmed that construction on the massive new plant has officially begun. Kevin Zhang, the deputy co-chief operations officer and senior vice president for the company, spoke to reporters on Tuesday right before the conference kicked off. He stated that the company is aggressively expanding its own unique capabilities right inside the current Arizona facility.
Zhang laid out the exact technological goals for the new American plant. He confirmed that TSMC will build both CoWoS and complex 3D-IC capabilities at the Arizona site before 2029. CoWoS and 3D-IC are two of TSMC’s most advanced proprietary packaging technologies. Right now, global demand for these specific packaging methods is incredibly high, and the company simply cannot build the chips fast enough to keep up with orders.
The new plant will solve a massive logistical headache for American companies. Currently, massive tech giants like Apple and Nvidia already source raw chips from TSMC’s massive Arizona factory. However, because the Arizona plant lacks advanced packaging capabilities, the company must load many of those raw American-made chips onto airplanes and ship them all the way back to Taiwan just to finish the packaging process. Building a packaging plant in Arizona eliminates that expensive, time-consuming trip across the ocean.
TSMC is not the only company trying to fix this problem. Last year, Amkor Technology announced it was actively working with both Apple and Nvidia to build its own massive packaging factory in Arizona. Amkor hopes to finish building its factory by mid-2027 and begin production by early 2028, which would beat TSMC’s 2029 timeline. Recognizing the massive demand, Amkor and TSMC announced a partnership in 2024. They agreed to work together to bring several of TSMC’s most advanced packaging technologies to Arizona, though neither company has disclosed the exact financial details of the massive arrangement.
Zhang briefly addressed the ongoing relationship between the two massive tech manufacturers. He confirmed that technology discussions between Amkor and TSMC remain highly active. He noted that TSMC is partnering with Amkor to determine exactly what technological capabilities they can officially offer their shared customers.
The ultimate goal for both companies is to significantly accelerate the rate at which products can be manufactured entirely within the United States. Zhang admitted that there are still some moving parts regarding the final partnership details. However, he stated confidently that TSMC is considering all possible options to establish a highly diverse, resilient manufacturing footprint across the globe to protect its massive business.
