Secure Movement Of Data In Test


Historically, test data flowed out of the tester and was loaded into a file. But with heterogeneous integration, including chiplets and IP from multiple vendors, test data is now being streamed across the manufacturing floor where it can be used to make real-time decisions. Eli Roth, product manager for smart manufacturing at Teradyne, talks with Semiconductor Engineering about challenges in da... » read more

Challenges Of Testing Advanced Packages


The number of things that can wrong in assembly and test increases as more chips are added into a package. Testing is the usual guarantor of a reliable device, but in an advanced package there are all sorts of new issues — more contacts, different handling requirements, the necessary thermal conditions for test, and variation within the package. George Harris, vice president of global test se... » read more

High-NA EUV Progress And Problems


High-NA EUV will enable logic scaling for at least the next couple process nodes. It’s complex, expensive, and a feat of optical engineering, but there are a lot of components with mixed progress. Harry Levinson, principal lithographer at HJL Lithography, talks  about when this technology will likely show up, what problems still need to be resolved, and what comes next.

Challenges Of Heterogeneous Integration


Heterogeneous integration opens the door to an almost unlimited number of features in a single package, but it also adds system-level challenges into a small space filled with a whole spectrum of possible interactions. Mike Kelly, vice president of chiplets/FCBGA integration at Amkor Technology, talks about a variety of issues ranging from uneven aging, warpage, and different mechanical stresse... » read more

Challenges In Packaging 5G And 6G


Millimeter wave frequencies are essential for transferring more data more quickly, but they also require different packaging technology to minimize loss and drift. That opens up a number of tradeoffs around antenna in package, antenna on package, flexible circuits, and different substrates. Curtis Zwenger, vice president of R&D at Amkor Technology, talks about a host of new challenges rangi... » read more

How Curvilinear Mask Writing Affects Chip Design


As chips become more complex and features continue to shrink, it becomes more difficult to print shapes on photomasks. The ability to print curvilinear masks changes that equation, but not all of the pieces in the flow are automated today. Aki Fujimura, CEO of D2S, talks about what has to change, what will the impact be on design rules, and why using curvilinear shapes can shrink the manufactur... » read more

Heterogeneous Integration Issues And Developments


There are a slew of new developments in advanced packaging, from new materials, chiplets, and interconnect schemes, to challenges involving how to physically put chips in a package, metallization, thermal cycling, and parasitics in the interconnect path. Dick Otte, CEO of Promex Industries, talks about how this will change chip design and manufacturing, and how those changes are likely to unfol... » read more

Increased Photomask Density And Its Impact On EDA


The ability to print curvilinear shapes on photomasks can have big repercussions on semiconductor design. Aki Fujimura, CEO of D2S, explains why mask rule checking has been bound by complex design rules, and why curvilinear shapes are important for reducing margin and simplifying the chip design process. » read more

Why Changes In Computing Are Driving Changes In Photomasks


Aki Fujimura, CEO of D2S, talks with Semiconductor Engineering about massive improvements in computation based upon increased density on chips, and why printing Manhattan shapes on a photomask are no longer sufficient to print high-performance devices with predictable reliability every time. He explains why a discontinuity in EDA physical design has opened the door for printing curvilinear shap... » read more

Deep Learning In Industrial Inspection


Deep learning is at the upper end of AI complexity, sifting through more data to achieve more accurate results. Charlie Zhu, vice president of R&D at CyberOptics, talks about how DL can be utilized with inspection to identify defects in chips that are not discernible by traditional computer vision algorithms, classifying multiple objects simultaneously from multiple angles and taking into accou... » read more
