Yield Is Top Issue For MicroLEDs
By Laura Peters - 11 Oct, 2022 - Comments: 0

MicroLED display makers are marching toward commercialization, with products such as Samsung’s The Wall TV and Apple’s smart watch expected to be in volume production next year or in 2024. These tiny illuminators are the hot new technology in the display world, enabling higher pixel density, better contrast, lower power consumption, and higher luminance in direct sunlight — while consu... » read more

Bump Co-Planarity And Inconsistencies Cause Yield, Reliability Issues
By Karen Heyman - 11 Oct, 2022 - Comments: 0

Bumps are a key component in many advanced packages, but at nanoscale levels making sure all those bumps have a consistent height is an increasing challenge. Without co-planarity, surfaces may not properly adhere. That can reduce yield if the problem is not identified in packaging, or it can cause reliability problems in the field. Identifying those issues requires a variety of process steps... » read more

Micron selected Syracuse, New York as the site for its new megafab complex, which is expected to create 9,000 company jobs and 40,000 construction and supply chain jobs. President Biden called it “another win for America.” The chip manufacturing facility will be the nation’s largest, including a 7.2 million square foot complex and 2.4 million square foot of cleanroom. Site preparation wil... » read more

Enabling Test Strategies For 2.5D, 3D Stacked ICs
By Laura Peters - 08 Sep, 2022 - Comments: 0

Improved testability, coupled with more tests at more insertion points, are emerging as key strategies for creating reliable, heterogeneous 2.5D and 3D designs with sufficient yield.  Many changes need to fall into place to make side-by-side 2.5D and 3D stacking approaches cost-effective, particularly for companies looking to integrate chiplets from different vendors. Today, nearly all of t... » read more

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
