November 13, 2023 /SemiMedia/ -- According to reports, a power outage occurred at onsemi's Bucheon wafer fab in South Korea on November 5, resulting in a temporary shutdown.

The power outage lasted approximately 20 minutes. However, because only a few equipment in the fab were equipped with uninterruptible power supplies, many equipment stopped operating during the power outage.

"Starting from last Monday, we successfully restored the normal operation of the production line through two days of work. The economic losses caused by the power outage were not very large," onsemi Korea executives said.

The report also mentioned that onsemi is considering closing its Bucheon factory for about two weeks starting around mid-December. "If industry conditions continue to decline, as far as we know, they will reduce production or temporarily close as early as December," a raw material supply chain source revealed.
