A former Samsung Electronics employee who later joined Chinese memory chipmaker ChangXin Memory Technologies, or CXMT, was reportedly sentenced by the Seoul High Court on Oct. 22 to five years in prison for leaking Samsung's technology.
The sentence was reduced from seven years at his first trial in April. The former employee had joined CXMT in 2016.
The case highlights an intensifying battle over semiconductor know-how as Chinese chipmakers narrow the gap with established rivals, putting the race for top engineering talent increasingly at odds with efforts to protect trade secrets.
In 2023, a South Korean court granted Samsung's request to block a former DRAM researcher from joining U.S. rival Micron. It ruled that the two-year non-compete was not excessive and was necessary to protect Samsung's technology and business information, JoongAng Ilbo reported.
A decade ago, Chinese memory chipmakers were not Samsung's biggest concern when it came to losing experienced engineers.
