MEMS Reliability

New methods are needed in microsystems technology for evaluating microelectromechanical systems MEMS because of their reduced size. The assessment and characterization of mechanical and structural relations of MEMS are essential to assure the long-term functioning of devices, and have a significant impact on design and fabrication. Within this study a concept for the investigation of mechanically loaded MEMS materials on an atomic level is introduced, combining high-resolution X-ray diffraction HRXRD measurements with finite element analysis FEA and mechanical testing. Latter were calculated by a specifically developed, simple and fast approach on the basis of continuum mechanical relations. Qualitative and quantitative analysis confirmed the admissibility and accuracy of the presented method.

A System for Calibration and Reliability Testing of MEMS Devices Under Mechanical Stress

Reliability and Failure of Electronic Materials and Devices is a well-established and well-regarded reference work offering unique, single-source coverage of most major topics related to the performance and failure of materials used in electronic devices and electronics packaging. With a focus on statistically predicting failure and product yields, this book can help the design engineer, manufacturing engineer, and quality control engineer all better understand the common mechanisms that lead to electronics materials failures, including dielectric breakdown, hot-electron effects, and radiation damage. This new edition adds cutting-edge knowledge gained both in research labs and on the manufacturing floor, with new sections on plastics and other new packaging materials, new testing procedures, and new coverage of MEMS devices. Professional Materials Engineers working with materials used in electronic devices, including silicon chips; Electronics Engineers; Electrical Engineers; Manufacturing Engineers; Chemical Engineers. From this perspective and the well-written tutorial style of the book, the reader will gain a deeper physical understanding of failure mechanisms in electronic materials and devices; acquire skills in the mathematical handling of reliability data; and better appreciate future technology trends and the reliability issues they raise.

Nanoelectromechanical systems NEMS are a class of devices integrating electrical and mechanical functionality on the nanoscale. NEMS typically integrate transistor-like nanoelectronics with mechanical actuators, pumps, or motors, and may thereby form physical, biological, and chemical sensors. The name derives from typical device dimensions in the nanometer range, leading to low mass, high mechanical resonance frequencies, potentially large quantum mechanical effects such as zero point motion , and a high surface-to-volume ratio useful for surface-based sensing mechanisms.

IEC 62047 Series - Micro-Electromechanical Devices - MEMS

Many highly integrated and easy to deploy condition monitoring products are appearing on the market that employ a micro electromechanical system MEMS accelerometer as the core sensor. These economical products help to reduce the overall cost of deployment and ownership, and in the process, expand the universe of facilities and equipment that can benefit from a condition monitoring program. S olid-state MEMS accelerometers have many attractive attributes when compared to legacy mechanical sensors, but unfortunately, their use for condition monitoring has been restricted to applications that can tolerate the use of lower bandwidth sensors for products, such as low cost, standards based smart sensors. In general, noise performance is not low enough to serve diagnostic applications, which require lower noise over higher frequency ranges and bandwidths beyond 10 kHz. As a technology based on solid-state electronics and built-in semiconductor fabrication facilities, a MEMS offers several compelling and valuable advantages to the designer of condition monitoring products. Putting aside the performance factor, here are the main reasons why MEMS accelerometers should be of interest to anyone in the field of condition monitoring. For airborne applications, such as in health and usage monitoring systems HUMS , weight is extremely expensive, with fuel costs of thousands of dollars per pound.

Suhir, , E. December ; 4 : Knowledge at the intersection of reliability, mechanical, materials, chemical, electrical, optical, manufacturing and software engineering holds the key to the viable and reliable microelectronics and photonics products and systems of the future. Our intent is to disseminate the state-of-the-art information pertaining to various reliability problems encountered in the design, manufacturing, testing, and operation of microelectronic, photonic and MEMS materials, devices, packages, equipment, and systems.

This 22 standard series starts from the basics with terms, definitions, and general specs, and continues on to a range of measurements and test methods such as those for fatigue, compression, bending, and shearing. IEC defines terms for micro-electromechanical devices including the process of production of such devices. This edition includes the following significant technical changes with respect to the previous edition: a removal of ten terms; b revision of twelve terms; c addition of sixteen new terms. Specifies the method for tensile testing of thin film materials with length and width under 1 mm and thickness under 10 m, which are main structural materials for micro-electromechanical systems MEMS , micromachines and similar devices. The main structural materials for MEMS, micromachines and similar devices have special features such as typical dimensions in the order of a few microns, a material fabrication by deposition, and a test piece fabrication by non-mechanical machining using etching and photolithography. This International Standard specifies the testing method, which enables a guarantee of accuracy corresponding to the special features.
