Semiconductor Manufacturing International Corporation: The fluctuation in Q1 yield is due to unexpected situations during maintenance and the need for verification of new equipment, etc.

On May 9, Jin10 reported that Zhao Haijun, co-CEO of SMIC (00981.HK), stated today that after the performance meeting held in February this year, on one hand, unexpected situations occurred during the company's annual maintenance, affecting the precision of product processes and yield issues. On the other hand, a significant number of new equipment was introduced in the first quarter, and during the equipment validation process, it was found that the performance and process capabilities of the equipment needed improvement, leading to fluctuations in product yield. These impacts are expected to continue for the next four to five months. As a single event, there has been no fundamental change for the company; however, it will take some time to raise the delivery of wafers from the production line to the highest standards.
