Request for Information (RFI) for Advancing Critical and Emerging Microelectronics Technologies I. Background Information The United States is in a battle for global leadership in the critical and emerging technologies that will drive decades of national and economic security and prosperity. To ensure U.S. global dominance in the industries of the future, we seek to advance the nation's stated agenda to secure the U.S. position as the unrivaled world leader in emerging technology. As the nation's premier laboratory with a mission to promote U.S. innovation and industrial competitiveness, Sandia National Laboratories (SNL) is poised to work with industry at every step to support U.S. manufacturing and technological capacity in critical and emerging microelectronics technologies. The basis for this RFI is aligned with the goal of advancing technology leadership in the United States and strengthening the supply chain for domestic semiconductor manufacturing. II.
