Who needs to check this?
Photoresist and electronic-materials suppliers serving semiconductor lithography.
Compliance tip
Confirm the resist is optimized for the specified exposure wavelengths. AT-only control means a license is needed only to a limited destination list; verify the Country Chart and screen all parties against the Entity and SDN lists.
Control Reasons
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
