Texas Instruments to buy Micron Technology 300-mm fab

Texas Instruments is acquiring Micron Technology’s 300-mm semiconductor fabrication facility in Lehi, Utah, for $900 million.


"This investment continues to strengthen our competitive advantage in manufacturing and technology and is part of our long-term capacity planning," said Rich Templeton, TI’s chairman, president and CEO.

The Lehi fab will be TI’s fourth 300-mm fab, joining DMOS6, RFAB1 and soon-to-be-completed RFAB2 in TI’s wafer fab manufacturing operations.

In addition to its value as a 300-mm fab, the acquisition is a strategic move, as Lehi will start with 65-nm and 45-nm production for TI’s analogue and embedded processing products and be able to go beyond those nodes as required.

"The Lehi fab is a great asset and a great team. We are excited about the engineering experience and technical skills the team brings in ramping and manufacturing advanced semiconductor processes," said Kyle Flessner, TI’s senior vice president of technology and manufacturing. 

The companies plan to complete the sale by the end of 2021. First revenue is expected in early 2023.

Micron Technology put the Lehi fab up for sale in March this year when it decided to pull the plug on 3D-XPoint non-volatile memory production.

3D-Xpoint was a joint development between Micron and Intel. Collaboration between the companies halted in 2018. Micron then became a foundry supplier of the devices for Intel.
