The Seoul High Court this summer upheld an 18-month prison sentence for a former SK hynix employee who had taken confidential company documents to strengthen job applications to Chinese firms.
According to South Korean media reports on August 9, the man was convicted after extracting sensitive materials from the Korean semiconductor group and using them as leverage in his search for employment in China. The case underscores the continuing risk of industrial espionage in the memory-chip and image-sensor supply chain, where proprietary know-how can be highly valuable to overseas competitors.
The original report does not provide further details on the specific documents involved, but the title indicates the stolen secrets concerned CMOS image sensors, a technology area in which SK hynix has strategic interests. The appellate ruling confirms the prison term imposed earlier, leaving the former employee with a final sentence of 18 months.
