U.S. Department of Justice Indicts Chinese Couple for Stealing Semiconductor Trade Secrets

Yu Haoyang, a Chinese-American couple living in Massachusetts, and their company have been indicted in federal court for allegedly stealing semiconductor trade secrets from a U.S. company, the U.S. Department of Justice announced on its website on October 1.

According to the indictment, Yu Haoyang, 41, from Harbin, came to the United States as a student in 2002 and became a naturalized U.S. citizen in 2017. 2014-2017, Yu Haoyang was employed as an engineer at Analog Devices, Inc.

During this period, Hao-Yang Yu downloaded hundreds of highly confidential integrated circuit design and model files worth millions of dollars and illegally stored them on his personal Google Cloud Drive.

Before resigning from the U.S. company in 2017, Mr. Yu founded another semiconductor company with his wife and began promoting and selling the software designs he obtained from ADI, even using ADI’s Taiwanese manufacturer to make the same IC components for him.

When Yu resigned from ADI in 2017, he signed a confidentiality document stating that he had returned all proprietary information and data, but he has since then actually kept the appeal information on his personal computer and netbook. Yu’s wife assisted him in his fraudulent activities.

The indictment also alleges that when Yu applied for U.S. citizenship in 2017, he failed to make an honest disclosure of the fact that he had ADI trade secrets.
