The March Toward Chiplets


The days of monolithic chips developed at the most advanced process nodes are rapidly dwindling. Nearly everyone working at the leading edge of design is looking toward some type of advanced packaging using discrete heterogeneous components. The challenge now is how to shift the whole chip industry into this disaggregated model. It's going to take time, effort, as well as a substantial reali... » read more

A New Dimension In Optical CD


One of the biggest challenges for nanoscale fabrication is how to measure devices on such a minute scale. As the semiconductor industry demands ever smaller devices, the need for reliable, robust measurements for quality control and process optimization increases. One robust and commonly used technique in semiconductor manufacturing is optical critical dimension (OCD) metrology. Standard, al... » read more

Nova METRION Use Cases


Several use cases that we will explore for the Nova METRION® system include contamination control, process excursion prevention, reactor matching, and uniformity control. The objectives of these use cases are to detect contaminants which can kill devices, improve barrier layer and source/drain function, maintain deposition uniformity that impacts downstream processes, and ensure wafer-to-wafer... » read more

Systematic Yield Issues Now Top Priority At Advanced Nodes


Systematic yield issues are supplanting random defects as the dominant concern in semiconductor manufacturing at the most advanced process nodes, requiring more time, effort, and cost to achieve sufficient yield. Yield is the ultimate hush hush topic in semiconductor manufacturing, but it's also the most critical because it determines how many chips can be profitably sold. "At older nodes, b... » read more

Metrology Of Thin Resist For High NA EUVL


One of the many constrains of high numerical aperture extreme ultraviolet lithography (High NA EUVL) is related to resist thickness. In fact, one of the consequences of moving from current 0.33NA to 0.55NA (high NA) is the depth of focus (DOF) reduction. In addition, as the resist feature lines shrink down to 8nm half pitch, it is essential to limit the aspect ratio to avoid pattern collapse. T... » read more

Legacy Tools, New Tricks: Optical 3D Inspection


Stacking chips is making it far more difficult to find existing and latent defects, and to check for things like die shift, leftover particles from other processes, co-planarity of bumps, and adhesion of different materials such as dielectrics. There are several main problems: Not everything is visible from a single angle, particularly when vertical structures are used; Various struc... » read more

Chip Industry Earnings: A Mixed Bag


Editor's Note: Updated the week of Oct. 31 and Nov. 7 for additional earnings releases. Although most companies reported revenue growth, this latest round of chip industry earnings releases reflected a few major themes: Lower future quarter guidance to varying degrees, due to the recent U.S. export restrictions related to China; Negative impact of the inflationary environment on corn... » read more

Week In Review: Manufacturing, Test


GlobalFoundries launched GF Labs, an “open framework of internal and external research and development initiatives that deliver a differentiated pipeline of market-driven process technology solutions for future data-centric, connected, intelligent and secure applications.” Greg Bartlett, GF's senior vice president of technology, engineering at quality, said the goal is to develop and exp... » read more

Week In Review: Manufacturing, Test


Chipmakers China’s Tsinghua Unigroup is in trouble. The group is the parent company of China’s YMTC, a 3D NAND supplier, and other chip ventures. It is close to moving into bankruptcy proceedings. Now, a consortium led by Alibaba has emerged as the frontrunner to take over Tsinghua Unigroup, according to a report from Bloomberg. That deal would keep the company afloat, the report said. ... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs As reported, Intel this week reorganized its operations following delays with its 7nm technology. Intel is behind TSMC and Samsung in technology. As a result, TSMC’s foundry customers, such as AMD, Nvidia and others, are also pulling ahead of Intel. In addition, reports have surfaced that Intel will outsource some of its leading-edge chip production to TSMC. To solve t... » read more
