Chang Chun Arizona Breaks Ground On Manufacturing Facility In Casa Grande

The semiconductor chemical facility will be operational in 2023, creating over 200 jobs


CASA GRANDE, AZ (October 20, 2022) — Chang Chun Arizona, a leading petrochemical supplier based in Taiwan, broke ground today on its first U.S. manufacturing facility in Casa Grande, Arizona. The facility is expected to be operational in 2023 and create over 200 jobs, contributing to the rapidly growing semiconductor manufacturing industry in Arizona, as well as economic development of the greater Casa Grande region.


Joined by the Arizona Commerce Authority, Casa Grande Mayor Craig McFarland and members of the Casa Grande City Council, and community leaders, the groundbreaking advances the state’s reputation as a national semiconductor leader and expands the state’s unrivaled semiconductor industry supply chain.


Representing a $300 million investment, the facility located in Casa Grande will produce electronic-grade hydrogen peroxide, tetramethylammonium hydroxide (TMAH)-based developers, electronic-grade solution and plating solution.


“Arizona is proud to welcome Chang Chun Arizona’s first U.S. manufacturing facility to Casa Grande,” said Governor Ducey. “Chang Chun Arizona represents yet another Taiwan-based semiconductor leader putting down roots in our state and adding to our vibrant advanced manufacturing landscape. As we continue to foster the world’s best environment for semiconductors, we look forward to partnering with Chang Chun and supporting their success for many years to come.”


“Chang Chun Arizona is incredibly grateful for the warm welcome extended by the entire State of Arizona,” said Yu-hung (Calvin) Su, President of Chang Chun Arizona. “By establishing our new facility in Arizona, this is a significant milestone in CCAZ’s expansion into the U.S. We are ready to meet the growing demand of the semiconductor industry in Arizona and throughout the U.S. We look forward to a long and prosperous relationship with the State of Arizona as well as contributing to the economic and environmental sustainability of the local community.”


The facility will support the state’s semiconductor industry by supplying essential high quality electronic grade chemicals used in the manufacture of the wafers. Chang Chun Arizona will start site development activities over the next few months and will start supplying wafer fabrication facilities in 2024. The facility will be fully built out in 2025 with opportunities for future expansion to meet demands of the advanced manufacturing market.


“Today’s groundbreaking demonstrates Arizona’s attractiveness as a global semiconductor leader,” said Sandra Watson, President and CEO of the Arizona Commerce Authority. “Chang Chun Arizona’s new facility bolsters our already vibrant semiconductor supply chain while creating new, high-tech jobs in Pinal County. We are grateful for Chang Chun Arizona’s commitment to Casa Grande and are excited to see the facility operational.”


“We are thrilled to welcome Chang Chun Arizona to our community and look forward to working with them as they establish their first American based manufacturing facility here in Casa Grande, AZ,” said Casa Grande Mayor Craig McFarland. “This new facility will support both the new TSMC facility and future advanced manufacturing development in Arizona. The semiconductor industry will help provide high quality jobs and further diversify our economy.”


“The addition of Chang Chun Arizona strengthens the Greater Phoenix semiconductor supply chain by providing materials essential to the chip manufacturing process," said Chris Camacho, President and CEO of the Greater Phoenix Economic Council. "CCAZ’s decision to open its first U.S. manufacturing facility in Greater Phoenix bolsters the region’s position as a top destination for semiconductor manufacturers globally and is a major investment that will provide hundreds of new high-wage jobs to our community.”
