United Microelectronics, the world's second largest contract chip maker, plans to reshuffle its management after the number two man at the company retires in October.
Peter Chang, vice chairman at UMC, plans to retire Oct. 1, but will continue to serve the company as a consultant, UMC said in a statement. Chang has worked for UMC and company affiliates for nearly 28 years, and has been a member of the executive team at the company for the past decade, including a stint as president and CEO.
In the wake of his impending departure, UMC announced plans to reorganize its management. The company plans to appoint Sun Shi-wei as chief operating officer for 12-inch operations, while W.Y. Chen will be appointed senior vice president in change of 8-inch and 6-inch operations. The 12, 8 and 6 inch sizes refer to the silicon wafers chips are manufactured on.
The largest wafers used today are 12-inches in diameter, while 8-inch wafers are considered mature technology and 6-inch is older technology. The larger the wafer, the more chips can be made on its surface, leading to increased efficiency because each wafer can take weeks or months to finish, depending on the type of chip. Hundreds or thousands of chips can be made on one wafer, depending on the type of chip and size of the silicon wafer.
UMC has created separate managers to serve customers using 12-inch technology, versus those requiring 8-inch and 6-inch wafers, because of the unique customer requirements that exist for the different sized technologies, the company said.
Sun will be responsible for factory operations, sales and profits or losses in 12-inch technologies, while Chen will hold similar responsibilities in the 8-inch and 6-inch segments, UMC said.
