SEALSQ Strengthens Its U.S. Post-Quantum Semiconductor Footprint with SEALSQ USA

The objective is to support U.S. efforts to onshore semiconductor production and reduce reliance on foreign supply chains

Arizona & New York to serve as strategic hubs for post-quantum microchip production

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company specializing in Semiconductors, PKI, and Post-Quantum technology hardware and software products, today reaffirms its commitment in strengthening its footprint in the U.S. via the planned establishment of a semiconductor manufacturing facility, through the expansion of SEALSQ USA. This initiative is expected to be a pivotal step in reinforcing the U.S. semiconductor supply chain by enabling the domestic production of cutting-edge post-quantum microchips.

Expanding OSAT Operations in the U.S.

SEALSQ USA’s expansion includes the planned establishment of a dedicated Outsourced Semiconductor Assembly and Test (OSAT) center, a critical move aiming to enhance the country’s semiconductor self-sufficiency. This OSAT facility is intended to deliver comprehensive semiconductor packaging, testing, and final assembly services, ensuring a robust and secure semiconductor production ecosystem within the U.S.

Key OSAT capabilities would include:

1. Wafer probing and final testing to ensure the highest quality standards in microchip production.
2. Advanced assembly solutions such as QFN, BGA, and WLCSP packaging to support diverse industry applications.
3. Reliability and qualification testing to meet the stringent security and performance requirements for quantum-resistant microchips.
   
   
   
   

The OSAT facility is expected to play a crucial role in securing a resilient and self-sustaining U.S. semiconductor ecosystem.

SEALSQ intends to strategically position its U.S. operations in Arizona and New York, two key regions driving semiconductor innovation:

1. Arizona: Already a semiconductor hub, Arizona offers an established infrastructure and workforce to support SEALSQ’s OSAT and manufacturing operations.
2. New York: Set to house SEALSQ’s office by Q2 2025, New York provides access to financial and technological resources to accelerate market deployment and industry partnerships.

SEALSQ has already incorporated SEALSQ USA in the state of Arizona with the intent of using this entity to house its OSAT and manufacturing operations. SEALSQ’s U.S. expansion aligns with overall efforts to onshore semiconductor production and reduce reliance on foreign supply chains. With evolving U.S. policies, including proposed tariffs on imported semiconductors, the demand for domestically produced, quantum-secure chips, is more urgent than ever. SEALSQ is poised to meet this demand by delivering next-generation, quantum-resistant semiconductor solutions that protect critical infrastructure, defense systems, and commercial applications worldwide.

As quantum computing continues to evolve, SEALSQ remains at the forefront of post-quantum cybersecurity and semiconductor innovation. With the aim to expand its OSAT operations and reinforce its U.S. presence, SEALSQ is looking to actively shaping the future of secure semiconductor technology, ensuring the development of resilient, cutting-edge solutions for a quantum-secure world.

About SEALSQ:

SEALSQ focuses on selling integrated solutions based on Semiconductors, PKI and Provisioning services, while developing Post-Quantum technology hardware and software products. Our solutions can be used in a variety of applications, from Multi-Factor Authentication tokens, Smart Energy, Smart Home Appliances, Medical and Healthcare and IT Network Infrastructure, to Automotive, Industrial Automation and Control Systems.

Post-Quantum Cryptography (PQC) refers to cryptographic methods that are secure against an attack by a quantum computer. As quantum computers become more powerful, they may be able to break many of the cryptographic methods that are currently used to protect sensitive information, such as RSA and Elliptic Curve Cryptography (ECC). PQC aims to develop new cryptographic methods that are secure against quantum attacks. For more information, please visit .
