SEOUL, Aug 9 (Reuters) – A former employee at SK Hynix has been sentenced to ‌18 months in jail for leaking information ‌on semiconductor manufacturing technology to a Chinese firm, the Yonhap ​news agency reported on Sunday.

The Seoul High Court made the ruling in an appeal case against the defendant, upholding the lower court’s sentence, for ‌leaking classified information ⁠on so-called CMOS image sensors, a technology used for non-memory chips in ⁠smartphone cameras and laptops, to a Chinese company in 2022, Yonhap said.

The court found that the ​employee, who ​formerly worked at ​SK Hynix’s office in ‌China, printed out or took photos of documents containing trade secrets downloaded from the company’s internal server, a violation of its security rules, according to Yonhap.

The defendant disclosed some of the ‌information in a resume submitted ​to a Chinese firm, Yonhap ​said, without naming ​the Chinese company.

The man admitted ‌all of the charges and ​most of ​the information he took was retrieved by the company, the report said.

The Seoul High Court ​did not ‌immediately respond to a Reuters request for ​comment outside business hours.
