Are Tiny MicroLEDs The Next Big Thing For Displays?


One of the latest emerging trends is a renewed focus on microLED technology. What is a microLED, and why is the industry focusing on this technology? As the name suggests, a microLED, or µLED, is a light-emitting diode (LED) – roughly 100 times smaller than conventional LEDs. MicroLEDs can be arranged into arrays to make high-resolution displays for applications ranging from smartwatches... » read more

The Race To Zero Defects In Auto ICs


Assembly houses are fine-tuning their methodologies and processes for automotive ICs, optimizing everything from inspection and metrology to data management in order to prevent escapes and reduce the number of costly returns. Today, assembly defects account for between 12% and 15% of semiconductor customer returns in the automotive chip market. As component counts in vehicles climb from the ... » read more

Measurement Of Deep Trenches To Study The RIE Lag Effect


The demand for accurate characterization of high aspect ratio geometries such as narrow gaps, deep trenches or deep holes arises in many technologies and industries. A variety of metrology techniques have been utilized to accommodate these needs. Among the candidates for this type of metrology, 3D optical profiling characterization is becoming more and more prevalent in process control. Due to ... » read more

Compound Semiconductor Innovation Advances EVs And Other Green Technologies


As the world works to reduce greenhouse gas emissions, global adoption of electric vehicles (EVs) is driving an increased demand for high-power, energy-efficient compound semiconductors, such as silicon carbide (SiC)-based components, throughout the entire EV assembly process. Renewable energy technology is now at the forefront of climate-forward research, with accelerating EV sales playing... » read more

Hidden Impacts Of Software Updates


Over-the-air updates can reduce obsolescence over longer chip and system lifetimes, but those updates also can impact reliability, performance, and affect how various resources such as memory and various processing elements are used. The connected world is very familiar with over-the-air (OTA) updates in smart phones and computers, where the software stack — firmware, operating systems, dr... » read more

Week In Review: Manufacturing, Test


It's earnings season, and despite widespread reports of capacity issues and shortages, the chip industry turned in relatively solid results across the board. Intel exceeded January guidance for Q1, reporting first-quarter GAAP revenue of $18.4 billion, a 7% year-over-year decrease, and a 1% decrease year-over-year on non-GAAP basis. Record revenue was achieved in the Network and Edge Group, ... » read more

Technical Paper Round-Up: April 19


New technical papers include selective etching, ISO 26262 test bench, hardware accelerators, RISC-V, lidar, EUV mask inspection, fault attacks, edge computing, gallium oxide, and machine learning for VLSI CAD-on-chip power grid design. Cutting-edge research is now a global effort. It extends from the U.S. Air Force, to schools such as MIT, and universities in Italy, Spain, Portugal, India, K... » read more

Source performance metrics for EUV mask inspection


Abstract "Rules are derived to obtain specifications on radiance, power, lifetime, and cleanliness of the source for an actinic patterned mask inspection system. We focus on the physical processes and technological aspects governing the requirements of radiation sources for reticle inspection. We discuss differences and similarities to scanner with respect to magnification, system etendue, a... » read more

Strategies For Faster Yield Ramps On 5nm Chips


Leading chipmakers TSMC and Samsung are producing 5nm devices in high volume production and TSMC is forging ahead with plans for first 3nm silicon by year end. But to meet such aggressive targets, engineers must identify defects and ramp yield faster than before. Getting a handle on EUV stochastic defects — non-repeating patterning defects such as microbridges, broken lines, or missing con... » read more

Week In Review: Manufacturing, Test


Deals AMD plans to purchase cloud startup Pensando for about US $1.9 billion. In a presentation at the SEMI ISS conference this week, AMD CTO Mark Papermaster described Pensando's technology as a "highly programmable packet-processing engine that allows you to speed up systems designed for the data center." Intel, Micron, Analog Devices and MITRE Engenuity formed an alliance to accelerate c... » read more
