Powerchip Semiconductor Manufacturing Corp. (PSMC) on Monday said it has completed the sale of its facility in Miaoli County to Micron Technology and will begin technology collaboration with the American memory chip maker in line with the agreement, according to a report by Focus Taiwan.

Following the transfer of the plant in Tongluo Township, the two companies will jointly work on developing high-bandwidth memory (HBM) and post-wafer-finish (PWF) foundry services, along with advanced memory process technologies, PSMC said in a statement.

The strategic partnership is expected to accelerate PSMC’s growth in its emerging 3D AI foundry business.

Under the deal, PSMC sold the plant to Micron for USD 1.8 billion. In return, the US company will provide technical assistance to help PSMC develop niche dynamic random access memory (DRAM) chip processes at its Hsinchu facility.

PSMC chairman Frank Huang said the company’s 3D AI foundry business has entered AI-related applications such as wafer-on-wafer (WoW), interposers and silicon capacitors.

“In the future, PSMC will provide HBM/PWF foundry services to Micron,” Huang said, adding that advancements in DRAM technology will help customers enter the 8G DDR4 product line and enhance the value of wafer manufacturing.

PSMC also said it will support Micron in accelerating the installation of advanced DRAM production lines at the Tongluo plant’s cleanrooms.

In a separate statement, Micron said the Tongluo facility is expected to begin supporting meaningful product shipments from the existing fabrication plant starting in fiscal year 2028.

Micron’s executive vice president for global operations, Manish Bhatia, said the facility complements the company’s operations in Taiwan and forms a key part of its global expansion strategy.

The company also plans to begin construction by the end of fiscal year 2026 on a second facility of comparable scale at the site, which will add about 270,000 square feet of cleanroom space.
