On Friday, Apple Inc’s chip supplier Taiwan Semiconductor Manufacturing Co said, a few of its production lines in southern Taiwan have been hit by a contamination of gases that are used in the chipmaking process.

The incident is unlikely to significant impact its operations, said TSMC.

In a report, Japanese news agency Nikkei reported, TSMC’s most advanced chipmaking facility, Fab 18, was hit by the gas leak.

TSMC produces all of its latest processors, including ones for the forthcoming Mac computers and iphones, were produced on that production line.

“To ensure that there will be no issues with production quality, TSMC is currently carrying out stringent follow-up operations,” said the company.

Apple did not immediately respond to request for comments.
