Engineer Sentenced to Over 5 Years in Prison for Conspiring to Illegally Export to China Semiconductor Chips with Military Uses

          LOS ANGELES – An electrical engineer who schemed to illegally obtain integrated circuits with military applications that were exported to China without the required filing of electronic export information was sentenced today to 63 months in federal prison.

          Yi-Chi Shih, 66, of Hollywood Hills, was sentenced by United States District Judge John A. Kronstadt, who also ordered him to pay $362,698 in restitution to the IRS and fined him $300,000.

          After a seven-week jury trial that concluded in July 2019, Shih was convicted of one count of conspiracy to violate the International Emergency Economic Powers Act (IEEPA), and the Export Administration Regulations (EAR). Shih also was convicted of four counts of mail fraud, two counts of wire fraud, one count of conspiracy to gain unauthorized access to a protected computer to obtain information, one count of making false statements to an FBI agent, three counts of subscribing to a false tax return, and four counts of making false statements to the IRS about his foreign assets.

          Shih defrauded a United States company that manufactured broadband, high-powered semiconductor chips known as monolithic microwave integrated circuits (MMICs) out of its confidential and proprietary business information that was part of its MMIC manufacturing services, according to trial evidence. As part of the scheme, Shih accessed the victim company’s web portal after obtaining that access through an associate who posed as a domestic customer seeking to obtain custom-designed MMICs that would be used solely in the United States. In this way, Shih concealed his true intent to export the U.S. company’s MMICs to the People’s Republic of China.

          The victim company’s semiconductor chips have several commercial and military applications. MMICs are used in missiles, missile guidance systems, fighter jets, electronic warfare, electronic warfare countermeasures and radar applications. The MMICs Shih exported to China were intended for AVIC 607, a state-owned entity in the PRC.

          Shih was the President of Chengdu GaStone Technology Company (CGTC), a Chinese company that was building a MMIC manufacturing facility in Chengdu. In 2014, CGTC was placed on the Commerce Department’s Entity List, according to court documents, “due to its involvement in activities contrary to the national security and foreign policy interest of the United States – specifically, that it had been involved in the illicit procurement of commodities and items for unauthorized military end use in China.”

          Shih used a Hollywood Hills-based company he controlled – Pullman Lane Productions, LLC – to funnel funds provided by Chinese entities to finance the manufacturing of the MMICs by the victim company. Pullman Lane received financing from a Beijing-based company that was placed on the Entity List the same day as CGTC “on the basis of its involvement in activities contrary to the national security and foreign policy interests of the United States,” according to court documents.

          Shih’s associate, Kiet Mai, pleaded guilty in December 2018 to one felony count of smuggling and was sentenced to 18 months’ probation and a $5,000 fine.

          The FBI, the United States Department of Commerce – Bureau of Industry and Security Office of Export Enforcement, and IRS Criminal Investigation investigated this matter with the assistance of the Royal Canadian Mounted Police.

          This case was prosecuted by Assistant United States Attorneys Judith A. Heinz of the National Security Division; Melanie Sartoris, Chief of the General Crimes Section; Khaldoun Shobaki of the Cyber and Intellectual Property Crimes Section; William M. Rollins of the Terrorism and Export Crimes Section; James C. Hughes of the Major Frauds Section; and Daniel G. Boyle of the Asset Forfeiture Section; with assistance from Elizabeth Cannon, Deputy Chief of the National Security Division’s Counterintelligence and Export Control Section.
