Exhibit 99.6

To clarify the report on Commercial Times on January 12th

1. Name of the reporting media: Commercial Times

2. Date of the report: 2005/01/12

3. Content of the report: UMC Transfers Large Orders to Hejian

4. Summary of the information provided by investors: None

5. Company’s explanation of the reportage or provided information:

UMC is releasing this statement in order to clarify the inaccurate reporting that appeared in a Commercial Times article on page 3 of the January 12th edition entitled “UMC Transfers Large Orders to Hejian.”

The companies mentioned in the report, including Texas Instruments, Xilinx, Infineon, Novatek, and MediaTek, are all independent companies that determine their foundry source based on their own business objectives. Accordingly, any decision they take regarding their foundry sourcing is in no way influenced by UMC. Clearly, the title of the article is inaccurate and misleading.

The article written by Mr. Chang and Miss Wang, journalists of the Commercial Times, has mistranslated and misinterpreted a statement made in a Morgan Stanley analyst report. The original report stated that certain UMC customers had started outsourcing to Hejian as a second source. In the Commercial Times article, however, the writers have stated that the decision was made by UMC. This is inaccurate, and the editors have made no attempt to get confirmation from the companies involved, printing a sensational headline in order to attract attention. This misreporting by the newspaper and its staff is clearly sufficient to influence the stock market, and those involved should be held legally responsible for their actions.

Certain analysts and media have regularly circulated false stories about listed companies that have caused damage to their corporate image and commercial reputations. UMC is prepared to pursue litigation in accordance with related legislation, including Articles 310 and 313 of the Criminal Code and Article 155 of the Securities Exchange Act, in any case in which such misreporting causes damage to the company’s shareholders and investors.
