Power of Attorney for SEC Filings

This filing details a Power of Attorney granted by Shih-Jye Cheng, an officer and director of CHIPMOS TECHNOLOGIES INC., to Hsiu-Ling Teng and I-Fan Kung. The attorneys-in-fact are authorized to act on Mr. Cheng's behalf for all necessary actions related to submitting and filing forms, schedules, and other documents with the U.S. Securities and Exchange Commission (SEC) using the EDGAR system. This includes obtaining EDGAR codes, preparing and executing SEC filings such as Forms 3, 4, 5, Schedules 13D and 13G, and Forms 144, and managing the EDGAR account. The power of attorney also allows the attorneys-in-fact to obtain information about transactions in the Company's equity securities from third parties. The document clarifies that this Power of Attorney authorizes, but does not require, the attorneys-in-fact to act; it does not relieve Mr. Cheng of his compliance responsibilities with Section 13 or Section 16 of the Exchange Act. The Power of Attorney revokes all previous powers of attorney and remains in effect until Mr. Cheng is no longer required to make such filings.
