Vinnova supports AlixLabs AB for feasibility study within the new electronic components and systems program in areas of Swedish excellence
Dr. Amin Karimi , R&D and Operational Manager and co-founder, said, "In the 'In-situ mask creation for fabrication of state-of-the-art nanoelectronics' project, we aim to evaluate our APS-process for selective creation of an in-situ mask for devices with critical dimensions below 10 nm. The process takes place in one single wafer etch process chamber without breaking the vacuum. We aim at a disruptive breakthrough in semiconductor nanofabrication technology as etch mask creation and manipulation in high volume manufacturing is a very complicated process with dedicated process tools and equipment at a high total expense."
The APS method is covered by core IP in the USA , Taiwan , and Europe . Dr. Dmitry Suyatin, CTO and co-founder of AlixLabs, stated, "In APS, the sidewalls of nanoscale features act as a topological mask in combination with Atomic Layer Etch Processes and can be used to initiate splitting of the nanostructures. Previously we have verified the process for nanowires for such different materials as gallium phosphide (GaP) and Silicon (Si), and now we have the evidence also for bulk silicon by creating features with sizes below 10 nm."
The APS method is complementary for single exposure Immersion Deep UV (DUV) and Extreme UV (EUV) Lithography and corresponding multiple patterning technologies like self-aligned double and quadruple patterning (SADP resp. SAQP) as well as multiple exposure lithography-etch and directed self-assembly (DSA) patterning. However, APS can considerably reduce the complexity, capital expenditure, and environmental footprint of wafer manufacturing. Demonstrating pitch splitting in bulk silicon by creating sub-10 nm structures has been a significant milestone for AlixLabs.
