MicroLEDs Move Toward Commercialization
By Laura Peters - 29 Aug, 2022 - Comments: 1

The market for MicroLED displays is heating up, fueled by a raft of innovations in design and manufacturing that can increase yield and reduce prices, making them competitive with LCD and OLED devices. MicroLED displays are brighter and higher contrast than their predecessors, and they are more efficient. Functional prototypes have been developed for watches, AR glasses, TVs, signage, and au... » read more

Week In Review: Manufacturing, Test
By Karen Heyman - 26 Aug, 2022 - Comments: 0

Regional Shifts Supply chains are moving away from China. Apple, Honda, and Mazda are in line to diversify their manufacturing across different regions, according to one report. Another report says Apple plans to manufacture some of its new iPhone 14s in India. Mexico wants to be part of U.S.’s drive to move chip manufacturing closer to home, hosting American financiers to discuss elect... » read more

Plasma Dicing 101: The Basics
By Richard Barnett - 15 Aug, 2022 - Comments: 0

Taking place at the end of the semiconductor process flow, dicing is the process where the silicon wafer is finally turned into individual chips, or die, traditionally by means of a saw or laser. A saw blade, or laser, is used to cut the wafer along the areas between the chips called dicing lanes. This step separates the chips from the wafer making them ready to be packaged and fitted to whiche... » read more

How Overlay Keeps Pace With EUV Patterning
By Laura Peters - 09 Aug, 2022 - Comments: 1

Overlay metrology tools improve accuracy while delivering acceptable throughput, addressing competing requirements in increasingly complex devices. In a race that never ends, on-product overlay tolerances for leading-edge devices are shrinking rapidly. They are in the single-digit nanometer range for the 3nm generation (22nm metal pitch) devices. New overlay targets, machine learning, and im... » read more

Nanosheet FETs Drive Changes In Metrology And Inspection
By Karen Heyman - 09 Aug, 2022 - Comments: 0

In the Moore’s Law world, it has become a truism that smaller nodes lead to larger problems. As fabs turn to nanosheet transistors, it is becoming increasingly challenging to detect line-edge roughness and other defects due to the depths and opacities of these and other multi-layered structures. As a result, metrology is taking even more of a hybrid approach, with some well-known tools moving... » read more

Week In Review: Manufacturing, Test
By Karen Heyman - 29 Jul, 2022 - Comments: 1

The U.S. Congress approved the CHIPS Act, a mammoth bipartisan achievement the New York Times called “the most significant government intervention in industrial policy in decades.” As passed, the full package — now called the Chips and Science Act — contains $52 billion in direct assistance for the semiconductor industry, along with $24 billion in tax incentives. In addition, the bill c... » read more

Hybrid Bonding Moves Into The Fast Lane
By Laura Peters - 21 Jul, 2022 - Comments: 1

The industry’s unquenchable thirst for I/O density and faster connections between chips, particularly logic and cache memory, is transforming system designs to include 3D architectures, and hybrid bonding has become an essential component in that equation. Hybrid bonding involves die-to-wafer or wafer-to-wafer connection of copper pads that carry power and signals and the surrounding diele... » read more
