Samsung engineer leaked secret DRAM manufacturing information to the Chinese for five years by writing it in a notebook
There is information in the media about a high-profile case of industrial espionage, and this time the victim of valuable information leakage was Samsung, one of the leaders in the manufacture of RAM chips.
What is known
The South Korean prosecutor's office accused a former Samsung engineer of passing secret DRAM manufacturing information to the Chinese company ChangXin Memory Technologies for five years.
Realizing that Samsung's digital infrastructure security system was at the highest level, the employee painstakingly recorded technical data in a notebook and thus leaked information to competitors. The stolen data included precise technical parameters: gas flow ratios, photoresist settings used at critical stages of lithography and deposition, and much more.
As a result, Samsung and the South Korean economy suffered trillions of won in losses, while ChangXin Memory Technologies was able to bypass more than 600 manufacturing stages and set up its own RAM production two years ahead of schedule, making it the largest Chinese manufacturer and now claims up to 15% of the global DRAM market.
