wccftech - TSMC’s U.S. Fab Is Top Priority Assures Former Chairman of TSMC Supplier Toppled in Power Bid
 
“The Taiwan Semiconductor Manufacturing Company's (TSMC) major supplier for its planned U.S.  fab, Jiangxi Hantang System Integration Co., has assured customers and investors that the facility remains its top priority. The company underwent a power struggle earlier in Taiwan today, which led to significant changes to its board of directors and management and resulted in its chairman being replaced. Hantang is responsible for helping TSMC set up environmentally controlled cleanrooms inside its chip fabrication facilities, and the assurance came in the form of a statement made by the company's largest investor and new chairperson.
 
Today's news marks the culmination of a months-long power struggle at the company, which saw its largest shareholder, Ms. Li Huiwen, succeed in her bid to replace the board of directors with a consortium of representatives of investment banks and industry members. Following today's shareholder's meeting, which took a vote to elect the new board members, Ms. Huiwen also successfully became Hantang's new chairperson.
 
Following her election as chairperson, Ms. Huiwen also released a statement to the press. This statement briefly mentioned TSMC's U.S. chip plant, with the executive simply stating that her company will work with the fab's management team to execute all plans successfully.
 
Industry reports floating in Taiwan last month had confirmed statements made by Hantang's former management that it would formalize all contracts with TSMC in July. Hantang is expected to begin installing cleanroom equipment in Arizona by September next year, and TSMC targets the facility to enter mass production by 2024.”
 
I know this might not be the most exciting industry news, but it could potentially have a large impact.  Jiangxi Hantang System Integration Co. is the key subcontractor for the TSMC Arizona plant and a board room coup just wasn’t needed right now.

I like your title better and will change mine, if you don't mind.
 
From what I gathered trying to find more information, which is murky, there is some question whether or not the TSMC contract will be a priority.  JASIC HQ is in Nanchang, PRC, so who knows what's the real story.

My $$$ is on them never building it regardless of company politics

Building this fab in the US wasn’t TSMC’s idea. They don’t need it. America does.

Taiwan has plenty room for more fabs.
