Chipmakers Getting Serious About Integrated Photonics

By Brian Bailey - 12 Jul, 2021 - Comments: 2

Integrating photonics into semiconductors is gaining traction, particularly in heterogeneous multi-die packages, as chipmakers search for new ways to overcome power limitations and deal with increasing volumes of data. Power has been a growing concern since the end of Dennard scaling, which happened somewhere around the 90nm node. There are more transistors per mm², and the wires are thinne... » read more

What Makes A Chip Tamper-Proof?

The cyber world is the next major battlefield, and attackers are busily looking for ways to disrupt critical infrastructure. There is widespread proof this is happening. “Twenty-six percent of the U.S. power grid was found to be hosting Trojans," said Haydn Povey, IAR Systems' general manager of embedded security solutions. "In a cyber-warfare situation, that's the first thing that would b... » read more

Measuring molecules The Technical University of Munich (TUM) has developed a new metrology technique that determines the properties of individual molecules. The technique, called single-molecule excitation–emission spectroscopy, improves upon the traditional methods to explore molecules. The traditional method, dubbed single-molecule spectroscopy (SMS), is not new and is used to analyze f... » read more

China’s powerful laser The Shanghai Superintense-Ultrafast Lasers Facility (SULF) in China claims to have demonstrated the world’s most powerful laser. The ultra-intense, ultra-fast laser is said to have delivered a peak power of more than five petawatts. This is supposedly the largest peak-power laser pulse ever measured on record. A petawatt is equivalent to one quadrillion watts. ... » read more

Microbunching EUV Researchers at the SLAC National Accelerator Laboratory have provided a status report on its ongoing efforts to develop a steady-state microbunching (SSMB) technology. SSMB is a technology used within a storage ring, which is a large-scale, circular particle accelerator. An SSMB mechanism produces a high-power radiation source within the ring. This, in turn, could enable a... » read more

Diamond shock waves For years, the industry has been exploring the use of diamonds for electronics applications. Diamonds could be used to reduce heat in electronic systems. In addition, diamond FETs are also intriguing. Diamond has a wide bandgap (5.45 eV), a high breakdown field (10MV/cm), and high thermal conductivity (22W/cmK). But it could take years before diamond FETs reach the mains... » read more

Table-top EUV Swinburne University of Technology has developed a table-top extreme ultraviolet (EUV) laser power source. The source could be used to develop a system for use in metrology and other applications. The table-top setup is a new way to generate bright beams of coherent EUV radiation. It may offer a cost-effective alternative to large-scale facilities, such as synchrotrons or free... » read more
