Overview

Far outside the realm of typical integrated circuits, there exists a myriad of devices with astonishing properties that are nonetheless fabricated in silicon and other semiconducting materials. Microscopic membranes deflect and deform under fluctuations in atmospheric pressure, creating an electrical signal that can be digitized as sound; an extensive array of silicon springs and plates shift under the influence of external forces, serving as an accelerometer; an infinitesimally small array of metallic mirrors actuated by electrostatic forces can serve as one of the primary components in a theater projector or television. Though these devices have widely divergent purposes, they all have one thing in common: all are Micro-Electro-Mechanical systems (MEMS), and all pose a significant challenge for a failure analyst.

Fundamentals

In addition to the potential issues faced by any integrated circuit - electrical and mechanical stresses, contaminants, and so on - failure analysis of a MEMS is complicated by the fact that these devices are comprised of microscopic moving elements, adding an entirely new dimension to the analysis. For example, a device may fail as a result of “stiction” - an element failing to move properly, perhaps as a result of an incomplete release etch, a foreign particle, electrostatic attraction, or other mechanisms - or from mechanical fatigue, the natural wear and tear of constant motion resulting in a drift in performance over a product’s lifetime. Further complicating matters, many MEMS devices are securely sealed, as a way to protect their fragile elements; to successfully disassemble such a product, an analyst must be familiar with a wide variety of chemical and mechanical preparation methods, always keeping in mind the delicate nature of the sample. Many of an analyst’s tools can be adapted for MEMS work: infrared microscopy can often be used to inspect the MEMS elements for damage or anomalous material without breaking the device seal, as device lids are often made of silicon which is somewhat transparent to short wave infrared light; the focused ion beam can be used to cut windows in the lid of a MEMS to perform a high magnification inspection; and so on.

Sample types

IAL has experience with a wide range of MEMS devices, including extensive work with accelerometers, microphones, and pressure sensors, among others. As long as we can develop a method for replicating a failure on our test bench, chances are good that we can delve into the microscopic beams and gears of your MEMS and come out with the root cause of failure.

Applications

  • Analyzing “dead pixels” on a mirror-based imager array
  • Troubleshooting bad outputs from a silicon accelerometer

What is Scanning Electron Microscopy?

Scanning electron microscopy (SEM) is a electronics failure analysis tool used to examine surfaces and particles of electronic components and materials.   SEM is a technique capable of imaging structures and materials at resolutions well beyond the limits of optical microscopy.

A scanning electron microscope is a microscope that can produce images of an object as small as 1nm. The microscope’s electron beam interacts with the object's surface creating signals of x-rays, secondary electrons and backscatter electrons. These signals are used to form a high resolution image that appears 3D.

Scanning Electron Microscopy and Electronics Failure Analysis

The process of interpreting SEM images to track down defects in electronic components requires extensive training and experience.

SEM is an extremely powerful technique in the hands of experienced microscopists that specialize in electronics failure anlaysis. 

SEM is used to identify many types of defects and failure mechanisms in a vast array of electronic components. The IAL's SEM department has decades of experience using SEM to identify numerous failure mechanisms, including:

  • Metallurgical Failure Analysis
  • Wafer Lot Acceptance
  • Elemental Analysis (EDS)
  • Large area image acquisition (SEM Mosaics)
  • Solder Analysis

Overview

Though perhaps not as glamorous as highly integrated microprocessors or specialized ASICs, discrete components - thin-film resistors, chip capacitors, individual transistors, and so on - are still a vital part of modern electronics. A failing bipolar transistor or shorted capacitor can be just as catastrophic as a malfunctioning IC; fortunately, the tools and techniques of IC failure analysis are equally applicable to FA of discrete components.

Fundamentals

Discrete component failure analysis follows much the same path as an integrated circuit FA; indeed, analysis of a bipolar transistor or power MOSFET uses exactly the same tools, techniques, and procedures as more complex IC FA projects. Analysis of discrete components begins with non-destructive testing, where tools like x-ray imaging and acoustic microscopy are used to examine the device under test for damage or anomalous processing - for example, cracking in a ceramic capacitor, or irregularities in the laser trim on a precision metal film resistor. Next comes fault verification, where an analyst confirms that the reported problem - for example, a short circuit - is still present. After confirming the failure, the analyst applies a variety of different tools to preform fault isolation, identifying the most likely location of the defect. Depending on the type of device and the defect in question, different tools might be used. For example, thermal imaging is commonly used on leaky capacitors or thin film resistors with anomalous values (either too high or too low of a resistance value may be the result of a defect that will emit heat when biased), while photoemission microscopy (PEM) often reveals defects on semiconductor-based discrete devices. Finally, destructive analysis and documentation wraps everything up neatly: protective coatings or passivation layers are stripped away, the defect is photographed in all its glory, and the root cause of the failure is identified.

Sample types

From thermistors to capacitors, LEDs to FETs, and all points between, IAL’s failure analysis expertise extends to all varieties of discrete components. Our suite of test equipment and preparation tools is adaptable across any range of different samples; regardless of your product, be confident that IAL has applicable experience and can successfully identify the source of your troubles.
