Rapid advances in resistive oxide memory (OxRAM) could soon put the technology on manufacturers’ production lines.In a recent demonstration by CEA-Leti, 16-kbit arrays were successfully fabricated on 300 mm, 28 nm FDSOI wafers and run for 100,000 cycles with zero memory-point failures.OxRAM is affordable, high-density, and easy to manufacture. This latest demonstration also proves it […] >>

Piezoelectric Micromachined Ultrasonic Transducers, or PMUTs, are a type of MEMS. The devices are currently plagued by an angular resolution in excess of 90° in some cases.CEA-Leti brought the figure down to 18° for the detection of an object placed 40 cm away from the device. Their solution consisted of a network of five PMUTs […] >>

When photons interact with matter, a few per million are transformed into lower energy photons. In a specific kind of superconducting quantum circuit, the proportion of photons that undergo this transformation rises to one in three!Researchers at Irig recently discovered that the phenomenon is related to the nature of the circuit: a chain of large […] >>

In research for the European Union H2020 Pixapp project, CEA-Leti scientists have developed a sub-micron-precision passive automated microlens alignment process.If the new process’ potential is confirmed, it will allow photonic chips to be connected to several optical fibers five to ten times faster than today’s processes.Here’s how it works. First, capped copper bumps are placed […] >>

Ganil* in Caen has a new superconducting linear accelerator. Researchers at Irig recently tackled the challenge of achieving millibar-precision pressure control of 26 superconducting accelerator cavities cooled to 4.5 K by a liquid helium bath.The researchers used Simcryogenics, Irig’s simulation tool for large cryogenic equipment, to model the accelerator. The modeling and subsequent development of […] >>
