Quantum logic with spin qubits crossing the surface code threshold
By Technical Paper Link - 04 Apr, 2022 - Comments: 0

New research paper from QuTech, Delft University of Technology. Abstract "High-fidelity control of quantum bits is paramount for the reliable execution of quantum algorithms and for achieving fault tolerance—the ability to correct errors faster than they occur. The central requirement for fault tolerance is expressed in terms of an error threshold. Whereas the actual threshold depends o... » read more

Qubits made by advanced semiconductor manufacturing
By Technical Paper Link - 29 Mar, 2022 - Comments: 0

Abstract: "Full-scale quantum computers require the integration of millions of qubits, and the potential of using industrial semiconductor manufacturing to meet this need has driven the development of quantum computing in silicon quantum dots. However, fabrication has so far relied on electron-beam lithography and, with a few exceptions, conventional lift-off processes that suffer from low yie... » read more

Shrinking LEDs Researchers from King Abdullah University of Science and Technology (KAUST) are working to make LEDs smaller. Micrometer-scale light-emitting diodes (μLEDs) could be an ideal building block for future microLED displays, but devices based on nitride-based alloys used to achieve a broad color range become poor emitters of light when shrunk to micrometer scales. “The main ... » read more

Intermittent Undefined State Fault in RRAMs
By Technical Paper Link - 03 Sep, 2021 - Comments: 1

Abstract: " Industry is prototyping and commercializing Resistive Random Access Memories (RRAMs). Unfortunately, RRAM devices introduce new defects and faults. Hence, high-quality test solutions are urgently needed. Based on silicon measurements, this paper identifies a new RRAM unique fault, the Intermittent Undefined State Fault (IUSF); this fault causes the RRAM device to intermittently c... » read more

Thinner Channels With 2D Semiconductors
By Katherine Derbyshire - 21 Jun, 2021 - Comments: 0

Moving to future nodes will require more than just smaller features. At 3/2nm and beyond, new materials are likely to be added, but which ones and exactly when will depend upon an explosion of material science research underway at universities and companies around the globe. With field-effect transistors, a voltage applied to the gate creates an electric field in the channel, bending the ban... » read more

Chasing After Carbon Nanotube FETs
By Mark LaPedus - 18 Mar, 2021 - Comments: 6

Carbon nanotube transistors are finally making progress for potential use in advanced logic chips after nearly a quarter century in R&D. The question now is whether they will move out of the lab and into the fab. Several government agencies, companies, foundries, and universities over the years have been developing, and are now making advancements with carbon nanotube field-effect transi... » read more

Power/Performance Bits: June 2

Neuromorphic memristor Researchers at the University of Massachusetts Amherst used protein nanowires to create neuromorphic memristors capable of running at extremely low voltage. A challenge to neuromorphic computing is mimicking the low voltage at which the brain operates: it sends signals between neurons at around 80 millivolts. Jun Yao, an electrical and computer engineering researcher at ... » read more

Testing In Context Gaining Ground
By Jeff Dorsch - 10 Dec, 2019 - Comments: 0

Testing in context is beginning to gain wider appeal as chip complexity increases, and as ICs are deployed in more safety-critical and mission-critical applications. While design in context has been the norm for SoCs for some time, a similar approach in test has been slow going. Cell-aware testing technology was first described a decade ago, and since then its adoption has been modest. But w... » read more

Manufacturing Bits: May 8
By Mark LaPedus - 08 May, 2018 - Comments: 0

Electrolyte transistors Delft University of Technology, the Centre National de la Recherche Scientifique (CNRS) and NTT have developed a nanotransistor technology that will make it easier to measure the concentration of different electrolytes in the body. Electrolytes involve nutrients and chemicals in the body. They perform important functions and a disruption of the electrolyte balance is... » read more
