"TSMC has contained the problem and found a solution, and recovery of the tools is in progress", it said in a statement.
TSMC is now the world's largest independent semiconducer in the industry, with the company making NVIDIA's new 12nm GPUs for their upcoming GTX 11 series graphics cards, and the new 7nm chips for Apple's new iPhones.
The virus struck late on Friday night and led to the closure of several TSMC factories, and some of these are still not operational. More detailed information on the situation will be shared on Monday. The company said it was confident shipments delayed in the third quarter will be recovered in the fourth quarter 2018, and maintained its forecast of high single-digit revenue growth for 2018 in USA dollars given on July 19, 2018.
A company that makes semiconductors for Apple iPhones says it is recovering from a virus outbreak but expects the incident to delay shipments and raise costs.
TSMC said the incident is expected to impact 3% of its third-quarter revenues, and delayed shipments in the third quarter will be recovered in the fourth quarter.
TSMC spent the weekend scrambling to get its operations back to normal.
The company didn't provide details on the source of the virus.
TSMC's chief financial officer Lora Ho told Bloomberg that the chipmaker has been attacked by viruses in the past, but never has malware affected the company's production lines. Currently, we don't know what impact, if any, this virus will have on the production of the new iPhone or on TSMC in general.
Aside from this issue, both Apple and TSMC are having a good year, with Apple boasting a market value in excess of $1 trillion.
TSMC has grown to become the largest independent semiconductor foundry in the world, with profits previous year of $11.6 billion.
