RF Device And Process Biz Heats Up


The RF device and process technology markets are heating up, especially for two critical components used in smartphones—RF switch devices and antenna tuners. RF device makers and their foundry partners continue to ramp up traditional RF switch chips and tuners based on RF SOI process technologies for today’s 4G wireless networks. And recently, [getentity id="22819" comment="GlobalFoundri... » read more

Time For Massively Parallel Testing


Time is money in electronics, as in other industries, and the more time that is invested in testing chips means more costs being added to the product in question. To speed up testing for memory devices and other semiconductors, test equipment vendors have resorted to parallel testing technology, simultaneously testing multiple chips at a time. The industry also is turning to system-level tes... » read more

How Testing MEMS, Sensors Is Different


When it comes to testing microelectromechanical system devices and sensors, sometimes you have to shake and bake. [getkc id="311" comment="MEMS"] and [getkc id="187" kc_name="sensors"] are physically different from standard ICs. They require a specific type of stimulus to get the required testing results. Most chips only need to have an electrical charge run through them to gauge their pass/... » read more

What’s New On The MEMS Horizon?


In my previous blog post, I discussed emerging trends and the increased demand for MEMS; now I’ll focus on what we can expect in the immediate future in terms of new device technologies and MEMS-enabled products. While the more well-known MEMS such as accelerometers, gyroscopes, microphones and pressure sensors continue to grow in volume as they find new applications in things like wire... » read more

MEMS Microphones: A Bright Spot Among Commoditized Consumer Sensors


MEMS microphones have emerged as a bright spot among consumer sensors, which in general are going through a rapid commoditization and profit-squeezing trend. To understand what’s driving the MEMS microphone market, consider that the Apple iPhone 7 and 7S each have 4 MEMS microphones. As reported by System Plus Consulting, the latest iPhones have “a front-facing top microphone, presumably f... » read more

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

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

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

MEMS: A Tale Of Two Tough Markets


The MEMS market is growing rapidly, profits not so much. In most market segments, this would be a signal that more automation and standardization are required. But in the microelectromechanical systems world, fixes aren't so simple. And even where something can be automated, that automation doesn't work all the time. In fact, while MEMS devices are extremely difficult to design, build and ma... » read more

New Techniques To Analyze And Reduce Etch Variation


Time division multiplex (TDM) plasma etch processes (commonly referred to as Deep Reactive ION Etching [“DRIE”]) use alternating deposition and etch steps cyclically to produce high aspect ratio structures on a silicon substrate. These etch processes have been widely applied in the manufacturing of silicon MEMS devices, and more recently in creating through silicon vias in 3D silicon struct... » read more
