Chiplet Reliability Challenges Ahead


Assembling chips using LEGO-like hard IP is finally beginning to take root, more than two decades after it was first proposed, holding the promise of faster time to market with predictable results and higher yield. But as these systems of chips begin showing up in mission-critical and safety-critical applications, ensuring reliability is proving to be stubbornly difficult. The main driver fo... » read more

Better Analytics Needed For Assembly


Package equipment sensors, newer inspection techniques, and analytics enable quality and yield improvement, but all of those will require a bigger investment on the part of assembly houses. That's easier said than done. Assembly operations long have operated on thin profit margins because their tasks were considered easy to manage. Much has changed over the past several years, however. The r... » read more

Week In Review: Auto, Security, Pervasive Computing


Pervasive computing — data center, edge, IoT, 5G Qualcomm settled its 5G licensing disagreement with Huawei, which will pay $1.8 billion in back royalties and will pay for licensing going forward. Huawei is also now the world’s largest supplier of smartphones, surpassing Samsung Electronics Co. Qualcomm also announced a super-fast charging platform this week for Android devices that is sup... » read more

Next Challenge: Parts Per Quadrillion


Requirements for purity of the materials used in semiconductor manufacturing are being pushed to unprecedented — and increasingly unprovable — levels as demand for reliability in chips over increasingly longer lifetimes continues to rise. And while this may seem like a remote problem for many parts of the supply chain, it can affect everything from availability of materials needed to make t... » read more

Challenges For A Post-Moore’s Law World


Semiconductor Engineering sat down to discuss challenges at the edge, the impact of open-source, and how to attract new talent, with Simon Segars, CEO of Arm; Joseph Sawicki, executive vice president of IC EDA at Mentor, a Siemens Business; Raik Brinkmann, CEO of OneSpin Solutions; Babak Taheri, CEO of Silvaco; John Kibarian, CEO of PDF Solutions; and Prakash Narain, CEO of Real Intent. The con... » read more

Advanced Packaging Makes Testing More Complex


The limits of monolithic integration, together with advances in chip interconnect and packaging technologies, have spurred the growth of heterogeneous advanced packaging where multiple dies are co-packaged using 2.5D and 3D approaches. But this also raises complex test challenges, which are driving new standards and approaches to advanced-package testing. While many of the showstopper issues... » read more

Monitoring IC Abnormalities Before Failures


The rising complexities of semiconductor processes and design are driving an increasing use of on-chip monitors to support data analytics from an IC’s birth through its end of life — no matter how long that projected lifespan. Engineers have long used on-chip circuitry to assist with manufacturing test, silicon debug and failure analysis. Providing visibility and controllability of inter... » read more

Design And Measurement Requirements For Short Flow Test Arrays To Characterize Emerging Memories


Emerging non-volatile memories are becoming increasingly attractive for embedded and storage-class applications. Among the development challenges of Back-End integrated memory cells are long learning cycle and high wafer cost. We propose a short-flow based characterization of Memory Arrays using a Cross Point Array approach. A detail analysis of design requirements and testability confirms feas... » read more

Data Becomes Key For Next-Gen Chips


Data has become vital to understanding the useful life of a semiconductor — and the knowledge gleaned is key to staying competitive beyond Moore’s Law. What's changed is a growing reliance earlier in the design cycle on multiple sources of data, including some from further right in the design-through-manufacturing flow. While this holistic approach may seem logical enough, the semiconduc... » read more

Chip Reliability Vs. Cost


Semiconductor Engineering sat down to discuss the cost, reliability and security with Simon Segars, CEO of Arm; Joseph Sawicki, executive vice president of IC EDA at Mentor, a Siemens Business; Raik Brinkmann, CEO of OneSpin Solutions; Babak Taheri, CEO of Silvaco; John Kibarian, CEO of PDF Solutions; and Prakash Narain, CEO of Real Intent. What follows are excerpts of that virtual conversation... » read more
