Last month, the BIS introduced new export control regulations under the Export Administration Regulations (EAR), requiring semiconductor manufacturers and OSAT providers to conduct enhanced due diligence on chips using 16nm/14nm nodes or more advanced process nodes.
The regulations have also seen BIS introduce a whitelist of chip design companies and OSAT providers.
Effective Jan. 31, the new rules have already begun impacting the production and delivery of advanced chips for some Chinese semiconductor companies.
Foundries such as TSMC can manufacture advanced process chips for whitelisted design firms without restrictions, but non-whitelisted companies must either apply to the US Department of Commerce or ensure their final packaging and testing are handled by a whitelisted OSAT provider.
