Digital and analog electronics could soon be sharing space with a quantum system on a FD-SOI substrate cooled to 110 mK. Sound strange? Researchers from Leti and Irig recently designed a circuit with these unusual characteristics and presented it at a conference in February. It is only at the proof-of-concept stage. However, it does meet […] >>

Leti’s FD-SOI transistor model, used by companies like Samsung and STMicroelectronics, was recently recognized by the Si2 Compact Model Coalition, a working group made up of 30 international semiconductor industry stakeholders. The fact that Leti’s L-UTSOI model is now recognized as a standard model guarantees that it will be maintained and updated to meet the […] >>

Until recently, it was widely considered that the atomic force microscope (AFM) had hit a ceiling in terms of resolution. Researchers from Leti, CNRS, and Vmicro changed that with a new type of resonator. The conventional vibrating-cantilever-style probe, which tops out at around 1 MHz, has been replaced by a micrometric optically-excited silicon ring that […] >>

Some IC designers prefer to distribute their circuits’ functions across several physical bricks interconnected by a passive interposer. The approach is not new, but now the interposer is. Leti recently added logic (such as clock, I/O, voltage conversion, and other functions), making the interposer active. The institute designed, fabricated, assembled, and tested one with advanced […] >>

In research funded by the French National Research Agency (ANR), a team at Irig electrochemically functionalized silicon micropores. The very sensitive biosensors created in this way are suitable for use analyzing living cells. Their process, inspired by bipolar electrochemistry, involved placing two electrodes on either side of the pore. This technique usually requires voltages that […] >>
