Alphawave Semi has unveiled 3nm UCIe (universal chiplet interconnect express) die-to-die communication intellectual property, which has been demonstrated with TSMC’s chip-on-wafer-on-substrate (CoWoS) packaging. “This complete PHY and controller subsystem, developed with TSMC [using] TSMC’s CoWoS 2.5D silicon-interposer-based packaging, delivers a bandwidth density of 8Tbit/s/mm,” said Alphawave. It supports “PCIe, CXL, AXI-4, AXI-S, CXS, and CHI, features live per-lane health monitoring, ...

Gallium nitride-based LEDs and power transistors can be made on the same IC, according to scientists from Cornell University and the Polish Academy of Sciences. The trick is to used both sides of the wafer, and exploit a quirk of GaN. “GaN is unique among wide-bandgap semiconductors because it has a large electronic polarisation along its crystal axis, which gives ...

President Joe Biden, Vice-President Kamala Harris and former President Donald Trump have collected roughly $781 million from a variety of partisan interest groups up until June 30, 2024, according to data from the Federal Election Commission (FEC) collected and analyzed by the nonpartisan research group OpenSecrets. Not included is the reported $100 million in funds the Harris campaign raised in ...

LEM is aiming at electric vehicle state-of-charge estimation with a ±1.5kA current sensor. To be called the SMU series and designed to be built into the ‘battery disconnect unit’, the sensors “reach 1% of accuracy up to 1,300A and <1.7% up to 1,500A”, according to the company. The units measure 29.1 x 35.5 x 49.9mm, plus the dimensions of the ...

Irish quantum computing startup, Equal1 has signed a MoU with Nvidia to collaborate on quantum computing technology use cases, business models and proof of concept, focusing on integrating and validating the quantum-classical infrastructure for cloud and data centre deployment. Equal1 is developing scalable, cost-effective silicon spin qubits and has produced successful test chips, patented IP, and “achieved world-leading qubit performance, ...

August  chip inventories in Korea fell at the fastest rate for five years thanks to the  demand for memory, reports Statistics Korea. Inventories were down 42.6% y-o-y. In July they were down 34.3%. August chip production was up 10.3% and August shipments were up 16.1%. “Manufacturing industry, particularly semiconductors, is in a strong position, and the service industry is also ...

Raspberry Pi has announced a 12.3Mpixel AI camera, based on Sony’s IMX500 intelligent sensor, which “supports on-board processing for a variety of neural network models, leaving the processor in the host Raspberry Pi free to perform other operations,” according to Raspberry Pi. Alongside the image sensor is a RP2040 microcontroller for neural network frame firmware, a DSP and ram, and ...

The MoD has bought the old Fujitsu fab at Newton Aycliffe to make GaAs ICs for the military paying a reported £20 million. It will be renamed Octric Semiconductors UK. The Queen opened the fab in 1991 and Fujitsu did very well out of it on the back of the 4Mbit DRAM and had fully depreciated its $580 million investment ...

Hynix has begun mass production of a 36GB 12-layer HBM3E memory – the largest capacity HBM yet. The previous highest capacity HBM3E was 24GB using eight stacked 3GB die. ‘Hynix has increased the capacity by 50% by stacking 12 layers of 3GB DRAM chips at the same thickness as the previous eight-layer product,’ says Hynix, ‘to achieve this, the company ...

300mm fab equipment spending is projected to grow by 4% to $99.3 billion in 2024, and further increase by 24% to $123.2 billion in 2025, surpassing the US$100 billion level for the first time. Spending is forecast to experience 11% growth to $136.2 billion in 2026 followed by a 3% increase to $140.8 billion in 2027. “The magnitude of the ...
