Maximizing Design Flexibility For Multi-Layered And Diffractive Optical Components


A broad range of optical devices use nanostructured layers and surfaces to manipulate beams of light through diffraction and interference. Example devices include diffraction gratings, metasurfaces, diffractive optical elements, and metalenses. While the purpose and function of these devices can differ, they offer similar challenges from the point of view of simulation. In this white paper, ... » read more

Streamlining Failure Analysis Of Chips


Experts at the Table: Semiconductor Engineering sat down to discuss how increasing complexity in semiconductor and packaging technology is driving shifts in failure analysis methods, with Frank Chen, director of applications and product management at Bruker Nano Surfaces & Metrology; Mike McIntyre, director of product management in the Enterprise Business Unit at Onto Innovation; Kamran Hak... » read more

What Data Center Chipmakers Can Learn From Automotive


Automotive OEMs are demanding their semiconductor suppliers achieve a nearly unmeasurable target of 10 defective parts per billion (DPPB). Whether this is realistic remains to be seen, but systems companies are looking to emulate that level of quality for their data center SoCs. Building to that quality level is more expensive up front, although ultimately it can save costs versus having to ... » read more

Novel Family of Semiconductors


New research paper titled "Semiconducting silicon–phosphorus frameworks for caging exotic polycations" from researchers at Department of Chemistry, Iowa State University, and Ames Laboratory, U.S. Department of Energy. Abstract "A series of novel semiconductors AAe6Si12P20X (A = Na, K, Rb, Cs; Ae = Sr, Ba; X = Cl, Br, I) is reported. Their crystal structures feature a tetrahedral Si–P f... » read more

Power/Performance Bits: Feb. 16


Superconducting microprocessor Researchers at Yokohama National University created a superconducting processor with zero electrical resistance. Huge amounts of power are being used by computers today, and compared to the human brain, they are many orders of magnitude less efficient. Superconductors have been a popular approach to making computers more efficient, but this requires extreme co... » read more

Power/Performance Bits: Aug. 18


Flexible, hole-filled films Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) and Hongik University propose a simple way to make flexible electrodes and thin film transistors last longer: adding lots of tiny holes. A major problem with flexible electronics is the formation of microscopic cracks after repeated bending which can cause the device to lose its conducti... » read more

Power/Performance Bits: June 16


One-directional optical Researchers from University of Pennsylvania, Peking University and Massachusetts Institute of Technology developed a design for optical devices that radiate light in only one direction, which could reduce energy consumption in optical fiber networks and data centers. Light tends to flow in a single direction optical fibers, but while most of the light passing through... » read more

Power/Performance Bits: May 5


CMOS-compatible laser Researchers at Forschungszentrum Jülich, Center for Nanoscience and Nanotechnology (C2N), STMicroelectronics, and CEA-Leti Grenoble developed a CMOS-compatible laser for optical data transfer. Comprised of germanium and tin, the efficiency is comparable with conventional GaAs semiconductor lasers on Si. Optical communications provide much higher data rates, and are be... » read more

Power/Performance Bits: April 21


Focus-free lens Researchers from the University of Utah developed a new lens that doesn't require focusing. They present it as an alternative to the multiple lenses common in smartphone cameras. "Our flat lenses can drastically reduce the weight, complexity and cost of cameras and other imaging systems, while increasing their functionality," said research team leader Rajesh Menon from the U... » read more

Ansys SPEOS: Illuminating The Possibilities


Ansys SPEOS enables optical engineers to fine-tune critical factors such as propagation, reflection, visibility and legibility, while also identifying problems such as glare and hot spots. In a broad range of applications in the automotive, aerospace and general lighting segments, SPEOS cuts significant time and expense from the design cycle, while supporting the high degree of innovation neede... » read more
