Week In Review: Auto, Security, Pervasive Computing
By Susan Rambo - 29 Jul, 2022 - Comments: 0

Automotive, mobility Advantest installed its first enhanced T5851-STM16G tester of nonvolatile memory express (NVMe) solid-state drives (SSDs) using ball-grid arrays (BGAs) at a major manufacturer of IC memory devices. Anticipating the automotive market will be the largest consumer semiconductor ICs, Advantest designed the test machine to give system-level test coverage of NVMe BGA SSD devices... » read more

Week In Review: Manufacturing, Test
By Mark LaPedus - 23 Dec, 2021 - Comments: 0

Chipmakers TSMC has introduced another version of its 4nm process technology. The process, called N4X, is tailored for high-performance computing products. Recently, TSMC introduced another 4nm process, called N4P, which is an enhanced version of its 5nm technology. N4X is also an enhanced version of its 5nm technology. N4X, however, offers a performance boost of up to 15% over TSMC’s N5 pro... » read more

Fab tools Citing the outbreak of the coronavirus in China, SEMI has postponed Semicon/FPD China 2020 and related events originally scheduled for March 18-20, 2020. For the same reason, SEMI will no longer host Semicon Korea 2020 in Seoul, South Korea, February 5-7, as originally scheduled. ------------------------------- Veeco has introduced the new Lumina Metal Organic Chemical Vapor De... » read more

Silicon Photonics Begins To Make Inroads
By Kevin Fogarty and Ed Sperling - 09 Jul, 2019 - Comments: 1

Integrating photons and electrons on the same die is still a long way off, but advances in packaging and improvements in silicon photonics are making it possible to use optical communication for a variety of new applications. Utilizing light-based communication between chips, or in self-contained modules, ultimately could have a big impact on chip design. Photons moving through waveguides ar... » read more

Deprocessing And SEM For Semiconductor Failure Analysis
By Helle Ronsberg - 09 Jul, 2019 - Comments: 0

A typical semiconductor is fabricated from metal and barrier layers separated by passivation layers. A further glassivation and/or polyimide layer on top of these provides environmental and mechanical protection. Optical microscopes By using optical microscopy, the semiconductor die can be inspected for failure modes such as top-down visible crack degradation, melt-down of metal conductors,... » read more

Data Confusion At The Edge
By Ed Sperling - 11 Jun, 2019 - Comments: 0

Disparities in pre-processing of data at the edge, coupled with a total lack of standardization, are raising questions about how that data will be prioritized and managed in AI and machine learning systems. Initially, the idea was that 5G would connect edge data to the cloud, where massive server farms would infer patterns from that data and send it back to the edge devices. But there is far... » read more

Failure Analysis Of Electronic Devices Using Scanning Acoustic Microscopy
By Yavuz Kose - 11 Jun, 2019 - Comments: 0

Scanning acoustic microscopy, or SAM, is a non-destructive technique used in failure analysis of complex devices. SAM can provide a resolution down to sub-micron thicknesses. SAM is an efficient tool for analysis of adhesion between layers and presence of possible flaws in each layer. This can be used e.g. for investigations of sealing, coating, flip-chip underfills, BGA, QFN, wafer to wafer ... » read more

Hidden Soldier Joints Inspection: 4 Case Studies
By DELTA, a part of FORCE Technology - 07 May, 2019 - Comments: 0

IC packaging technologies are becoming smaller and thinner. Ball grid array (BGA) packages were introduced some years ago in order to save space on the PCB, and are now widely used. To overcome the resulting problems with using optical microscopy as an inspection tool, the endoscope found its way into quality engineering departments. To read more, click here. » read more

A Different Approach To Failure Analysis
By Yavuz Kose - 07 May, 2019 - Comments: 0

Decapsulation of plastic IC packages in different types and size were performed by wet chemical technique. Studied devices were to use in satellites and going to subject a series of test which require the die to be exposed. Different package types with changing sizes and bonding types such as Au- and Cu-bonded packages for unmounted and PCBA-mount components were successfully achieved. A combin... » read more

Gaps Emerge In Automotive Test
By Ed Sperling - 07 May, 2019 - Comments: 1

Demands by automakers for zero defects over 18 years are colliding with real-world limitations of testing complex circuitry and interactions, and they are exposing a fundamental disconnect between mechanical and electronic expectations that could be very expensive to fix. This is especially apparent at leading-edge nodes, where much of the logic is being developed for AI systems and image se... » read more
