Singular Photonics has spun out of the University of Edinburgh to offer two ultra-sensitive camera chips based on SPADs – single-photon avalanche detectors. Both have in-sensor digital signal processing. Development has been lead by Professor Robert Henderson, head of Edinburgh’s CMOS Sensors and Systems Group, and a pioneer of SPAD-based image sensors: he co-designed one in 2005, and in 2013 ...

PhotonDelta, the European hub for photonics, will launch a worldwide competition for new applications for photonics chips at PIC Summit 2024 (Eindhoven 15 October). Partners include imec, LioniX International, Smart Photonics, Phix Photonics Assembly, Ephiphan and Bright Photonics and engineering community platform Werolver. Engineers are invited to use photonics ICs in designs to tackle challenges in, for example, healthcare, AI, ...

Murata has opened a 200mm silicon capacitor manufacturing line at the French campus it acquired with IPDiA in 2016. “With the launch of this new line, we are continuing to invest in growing our production facilities and our local workforce,” said Murata Manufacturing president Norio Nakajima (picured). “It represents a significant step forward in our growth in the sector and ...

Onsemi has announced a 112 x 62mm power module for flying capacitor boost converters up to 1kV. It combines 1kV silicon IGBTs and 1.2kV silicon carbide diodes in the company’s F5BP package. Called NXH500B100H7F5SHG, it can handle continuous collector currents up to 210A (630A pulsed) (Tj = 175°C). Abs max power dissipation is 305W. To reducing stray inductance and thermal ...

Nexperia has introduced 80 and 100V mosfets in 5 x 6 and 8 x 8mm footprint LFPAK packaging with Rds(on) ranging from 1.8 to 15mΩ, or 2.07mΩ upwards for the 100V parts. “Many mosfet manufacturers focus on achieving high efficiency through low Qg(total) and low Qgd, when benchmarking the switching performance of their devices against alternative offerings,” said the company. ...

Imec has used 300mm wafers to demonstrate silicon-based quantum dot spin qubit processing. The devices had an average charge noise of 0.6µeV/√Hz at 1Hz. “In view of noise performance, the values obtained are the lowest charge noise values achieved on a 300mm fab-compatible platform,” according to the Belgian research lab. “By demonstrating those values, repeatedly and reproducibly this work makes ...

Infineon has announced a flurry of new power products as a prelude to PCIM in Nuremberg next week, the latest of which is a family of 600V super-junction mosfets. Its eighth generation, “the devices combine the best features of the 600V CoolMOS 7 series and are the successors to the P7, PFD7, C7, CFD7, G7 and S7 product families”, according ...

Empower Semiconductor is aiming at high-performance decoupling within IC substrates and interposers with its largest silicon capacitor yet, the 16.6μF EC1005P. “The performance of SoCs and other large computing processors are constantly increasing, said  Empower marketing manager Mukund Krishna. “It is becoming increasingly difficult to reach the level of power integrity and voltage regulation that these devices require with conventional ...

Oxford PV is claiming an efficiency record for solar panels based on perovskite-on-silicon tandem photovoltaic cells. “Produced in collaboration with the Fraunhofer Institute for Solar Energy Systems, the panel achieved a record 25% conversion efficiency, a significant increase on the more typical 24% efficiency of commercial modules,” according to the company. The panel was made using equipment and expertise at ...

Rohm has developed its first silicon capacitors, the 400 x 200 x 185μm ( 01005, 0402 metric) BTD1RVFL series which covers 100pF to 1nF. “The mounting area is reduced by approximately 55% over general 0201 [0603 metric] products to just 0.08mm2.” according to the company. “Moreover, a built-in transient voltage suppressor protection element ensures high ESD resistance.” They are rated ...
