MEMS: Improving Cost And Yield


MEMS devices inspire awe on the design side. On the test and manufacturing side, they evoke a different kind of reaction. These are, after all, the intersection of mechanical and electrical engineering—a joining of two miniature worlds that are the basis of some of the most complex technology on the planet. But getting these devices to yield sufficiently, understanding what does or does no... » read more

Testing For Security


Ever since the IoT became a household name, people have been strategizing about ways to utilize non-secure devices to mount an attack. The first instances of using electricity to overload a device's circuits, thereby neutralizing existing security features, came to light in some of the earliest car hacking incidents. These are basically side-channel attacks using what amounts to an electroni... » read more

Advanced Wafer Level Packaging Of RF-MEMS With RDL Inductor


The market for portable and mobile data access devices that are wirelessly connected to the cloud anytime and anywhere is exploding. The trend to access any network from anywhere is driving increased functional convergence in the radio, which translates into increased packaging complexity and sophistication. This is creating unprecedented demand for RF components providing more integration- in ... » read more

Quality Issues Widen


As the amount of semiconductor content in cars, medical and industrial applications increases, so does the concern about how long these devices will function properly—and what exactly that means. Quality is frequently a fuzzy concept. In mobile phones, problems have ranged from bad antenna placement, which resulted in batteries draining too quickly, to features that take too long to load. ... » read more

This tutorial covers the basics of analog sampling quality. Topics discussed in this white paper: Resolution Measurement Sensitivity Accuracy and Example Accuracy Calculations Difference between Precision and Accuracy Noise ... » read more

A Brief History of Test


The history of semiconductor test systems is the subject of this blog post. We’ll turn to printed circuit board testing at another time. Boston-based Teradyne sold its D133 diode tester to Raytheon in 1961. Five years later, it introduced the J259 integrated circuit tester, which had a minicomputer to run the test programs. For many, this marks the beginning of automatic (or automated) tes... » read more

2.5D Adds Test Challenges


OSATs and ATE vendors are making progress in determining what works and what doesn't in 2.5D packaging, expanding their knowledge base as this evolves into a mainstream technology. A [getkc id="82" kc_name="2.5D"] package generally includes an ASIC connected to a stack of memory chips—usually high-bandwidth memory—using an [getkc id="204" kc_name="interposer"] or some type of silicon bri... » read more

The Final Days…Getting To Sign-Off Faster With Calibre


With deadlines looming, the design flow between router output and final tape release can be stressful and frustrating. By combining a focused set of commands into macros, the Calibre YieldEnhancer tool enables designers to create customized, automated flows for engineering change order (ECO) filling, passive device insertion, custom fill to increase densities, jog removal, and via enhancements.... » read more

Crossing The Chasm: Uniting SoC And Package Verification


Wafer-level packaging enables higher form factor and improved performance compared to traditional SoC designs. However, to ensure an acceptable yield and performance, EDA companies, OSAT companies, and foundries must collaborate to establish consistent and unified automated WLP design and physical verification flows, while introducing minimum disruption to already-existing package design flows.... » read more

What Next For OSATs


Semiconductor Engineering sat down to discuss IC-packaging and business trends with Tien Wu, chief operating officer at Taiwan’s Advanced Semiconductor Engineering ([getentity id="22930" comment="ASE"]), the world’s largest outsourced semiconductor assembly and test (OSAT) vendor. What follows are excerpts of that conversation. SE: What’s the outlook for the IC industry in 2017? Wu:... » read more
