Two former employees of Semes, a Samsung Electronics subsidiary and key semiconductor chip-related equipment supplier, have been indicted for their alleged involvement in technology theft.
The two former Semes staffers were allegedly involved in selling crucial wafer cleaning machines -- believed to be identical to ones by Semes -- to an undisclosed Chinese entity, according to Suwon District Public Prosecutors’ Office on Tuesday. The pair and another two employees of a Semes’ supplier were indicted by the prosecutors on charges of violating the Unfair Competition Prevention and Trade Secret Protection Act. Those accused of technology theft reportedly obtained some 80 billion won ($62.6 million) in return. A spokesperson of Suwon District Public Prosecutors’ Office declined to comment further on the matter, adding, “It will take a few more weeks to complete the investigation.”The machines are considered as key to Samsung’s cutting-edge semiconductor chip technology.At the earliest stage of the chipmaking process, it is crucial to keep chip wafers clean with cleaning equipment. As the wafers became thinner, the process requires a more sophisticated approach.One of the ways to overcome the tech hurdle was for the equipment to use carbon dioxide in a supercritical fluid state to clean the wafer, which reduces damage to the wafer compared with cleaning with other fluids, like ultrapure water.
