Leti and Mapper, an equipment manufacturer based in the Netherlands, recently announced a major innovation: an individual security code etched onto the metal interconnects of individual chips during fabrication. Mapper developed a multiple electron beam maskless lithography test machine, which Leti integrated into a standard 40 nm CMOS fabrication process. The machine can be adapted […] >>

Leti will organize a day-long event for the tenth anniversary of the Heterogeneous Technology Alliance (HTA) on April 24 in Brussels. The strategic alliance brings together four top-tier European research institutes Fraunhofer, CSEM, VTT, and Leti. HTA’s members meet regularly to discuss their latest research, set up joint projects, and prepare joint proposals for EU […] >>

structures in which giant magnetoresistance (GMR) has been observed. Rather than stacking ultra-thin magnetic and non-magnetic layers, the researchers deposited the layers on the same surface. For example, two magnetic materials can be separated by a non-magnetic spacer a few dozen nanometers thick. The GMR variations measured on a pairing of cobalt and iron were […] >>

Since 2014, several scientific articles have presented the silicon-28 isotope as a good material for spin qubits for quantum computing. However, researchers had yet to produce the material in a CMOS environment, which uses natural silicon containing 4.7% isotope 29—not as suitable for qubits. INAC and Leti recently made a first step forward with the […] >>

Transition metal dichalcogenide (TMD) monolayers are promising candidates for future generations of transistors and for superconducting spintronics. The materials offer the advantage of retaining their superconducting properties even in the presence of very strong magnetic fields. Researchers at INAC dug deeper to come up with a theory to explain the phenomenon. They discovered that TMD […] >>
