TSMC’s supplier to open factory in U.S. to supply planned wafer fab

Taipei,  Chang Chun Petrochemical Co. Ltd. (長春化工) will build a plant in the U.S. state of Arizona to supply an advanced semiconductor fab that will be built there by Taiwan Semiconductor Manufacturing Co. (TSMC), the company and one of TSMC’s chemical suppliers said on Monday.

Based on the client’s demand, Chang Chun will seek land in Arizona for its new plant, where the company will produce electronic-grade hydrogen peroxide (H2O2), tetramethylammonium hydroxide (TMAH)-based developers, electronic-grade solution, and plating solution, the company said.

It noted the plan to build a factory in the U.S. will not affect its ability to fulfill the demand of its existing clients since the company plans to increase its output to guarantee a sustainable supply to the semiconductor sector.

At the same time, the company is planning to build a new plant in either Taichung City or Changhua County in Taiwan to produce high-concentrated H2O2, with the goal of producing 50,000 tons a year, Chang Chun said.

TSMC, the world’s largest semiconductor foundry, announced in May its intention to invest in an advanced semiconductor fab in the U.S. Construction is scheduled to start in 2021, with production targeted to begin in 2024.

The investment plan has attracted some of TSMC’s suppliers to follow suit, including United Integrated Services Co., a provider of electrical system integration engineering services, and Mirle Automation Corp., an automation equipment manufacturer, as well as several chemical producers.
