New 3D silicon chip breakthrough could extend Moore’s Law for years
New 3D silicon chip breakthrough could extend Moore’s Law for years - Date: - May 30, 2026 - Source: - University of Illinois Grainger College of Engineering - Summary: - As traditional chip miniaturization slows, researchers have found a way to pack more computing power into the same space by stacking silicon circuits in multiple layers. The new process uses ultra-thin silicon membranes and low-temperature manufacturing techniques to overcome a major obstacle that has long blocked the...
Silicon Photonics Testing: Design for Testability, Fault Detection, and Manufacturing Variation Analysis in Photonic Integrated Circuits
Announce Type: cross Abstract: This paper proposes a design-for-test (DFT) methodology and architecture for testing and validation of silicon photonic integrated circuits. We describe the design of silicon photonic circuits and components that comprise the proposed DFT architecture. The designs are extensively simulated and validated as test-access and fault-detection circuitry.
Novel Strip-like Readout Geometries in Resistive AC-coupled Silicon Detectors (RSD / AC-LGAD)
Announce Type: new Abstract: Resistive Silicon Detectors (RSD/AC-LGAD) are novel silicon detectors capable of both precise spatial and temporal resolution. Such sensors will be essential for the next generation of particle colliders (EIC, FCC-ee, CEPC, FCC-hh) and would enable the possibility of a 4D tracker. RSD sensors are typically fabricated with a pixel-like geometry that provides excellent spatial resolution in the x and y directions.

In-situ Silicon Doped hBN by High-Temperature Molecular Beam Epitaxy Enables Single Photon Emission
arXiv:2606.01727v1 Announce Type: new Abstract: Hexagonal boron nitride (hBN) has emerged as a leading host for optically active quantum defects. Yet introduction of specific impurity species other than carbon remains unexplored. Here, we demonstrate an in-situ silicon doping of hBN grown by high-temperature molecular beam epitaxy (HT-MBE).
NVIDIA's RTX Spark chip could give Windows its true Apple Silicon moment
NVIDIA's RTX Spark chip could give Windows its true Apple Silicon moment Arm CPU cores, a powerful GPU and gobs of unified RAM? That sounds familiar! There's a lot we still don't know about NVIDIA's RTX Spark AI chip — we're still waiting on deeper technical details and pricing for the first batch of systems — but it has a decent shot of changing the way we think of Windows PCs entirely.
Marvell enters the AI network fray with 102.4 Tbps switch silicon
Marvell enjoyed a fillip from Nvidia chief Jensen Huang at Computex, who praised the firm as it unveiled the latest 102.4 Tbps switch silicon it has purpose-built for AI infrastructure. The fabless semiconductor biz announced upcoming availability of its Teralynx T100 chip to coincide with the Taiwanese trade show, claiming that it needs 25 percent lower power than competitive solutions with lower latency for AI training and inference workloads. But the firm is late to this party, as other...
Programmable Silicon Retina on Pixel Processor Array
arXiv:2606.08370v1 Announce Type: cross Abstract: Standard dynamic vision sensors approximate retinal processing by detecting temporal contrast changes, offering high speed and high dynamic range. In this work, we explore whether incorporating additional biologically inspired processing stages - specifically spatial filtering and gain control - can offer advantages for certain downstream tasks such as saliency prediction. We present the first implementation of a multi-stage Silicon Retina...
macOS 27 requires Apple Silicon, as Apple draws down the Intel Mac era
As Apple announced last year, this year's macOS release will end support for Intel Macs. The macOS 27 Golden Gate release will require a Mac with an Apple Silicon chip inside, including the original M1 that launched in the MacBook Air, MacBook Pro, and Mac mini back in late 2020. Intel Macs running macOS 26 Tahoe can expect security and Safari patches for about two more years after the release of macOS 27 Golden Gate.
