"In this book, the authors present the basic science underlying the thermal and electrical stability of metal-dielectric interfaces and its relationship to the operation of advanced interconnect systems in gigascale electronics. Interface phenomena, including chemical reactions between metals and dielectrics, metallic-atom diffusion, and ion drift, are discussed based on fundamental physical and chemical principles. Schematic diagrams are provided throughout the book to illustrate interface phenomena and the principles that govern them."

"Teknologi alat akuisi seismic sudah semakin berkembang. Pada penelitian sebelumnya sudah dilakukan penelitian mengenai alat akuisisi sinyal seismik berbasis sensor accelerometer MEMS. Sehingga pada penelitian ini telah memperbaharui alat akuisisi sinyal seismik dari sisi komunikasi agar dapat mengakuisisi lebih banyak geophone atau alat akuisisi sinyal seismik. Selain itu agar jangkauan kabel atau jarak antar geophone juga semakin panjang. Keluaran data dari sistem ini hamper setara dengan keluaran data dari geophone konvensinal. Sistem ini menggunakan Modul SPI Extender untuk membuat satu buah Raspberry Pi dapat mengakuisisi geophone MEMS dengan lebih banyak dan jengan jangakaun kabel yang lebih panjang. Hasil respon atau keluaran dari geophone disimpan kedalam Raspberry Pi terlebih dahulu untuk kemudian bisa diambil secara wireless oleh komputer host. Uji coba dilakukan di Universitas Indonesia.

The technology of seismic acquisition instrumentation has getting developed. In previous research, a study of seismic signal acquisition instrumentation based on MEMS accelerometer sensor has been done. This research has renewed seismic signal accelerometer by communication aspect to acquire more geophones or seismic signal acquisition instrumentation. Output data of this system is almost same with output from conventional geophone. This system uses SPI Extender modul to make one Raspberry Pi to acquire more MEMS geophone and with further cable reach. Respond result or output of geophone is saved into Raspberry Pi first so that it can be taken wirelessly by host computer. Trial test is done at Universitas Indonesia."

"This book explains concepts behind fractional subsampling-based frequency synthesis that is re-shaping todays art in the field of low-noise LO generation. It covers advanced material, giving clear guidance for development of background-calibrated environments capable of spur-free synthesis and wideband phase modulation.

"Control from MEMS to atoms illustrates the use of control and control systems as an essential part of functioning integrated systems. The book is organized according to the dimensional scale of the problem, starting with micro-scale systems and ending with atomic-scale systems. Similar to macro-scale machines and processes, control systems can play a major role in improving the performance of micro- and nano-scale systems and in enabling new capabilities that would otherwise not be possible. However, the majority of problems at these scales present many new challenges that go beyond the current state-of-the-art in control engineering. This is a result of the multidisciplinary nature of micro/nanotechnology, which requires the merging of control engineering with physics, biology and chemistry."

"Interfaces between dissimilar materials are met everywhere in microelectronics and microsystems. In order to ensure faultless operation of these highly sophisticated structures, it is mandatory to have fundamental understanding of materials and their interactions in the system. In this revised method four fundamental disciplines are combined, (i) thermodynamics of materials, (ii) reaction kinetics, (iii) theory of microstructures, and (iv) stress and strain analysis. The advantages of the method are illustrated in Interfacial Compatibility in Microelectronics which includes, solutions to several common reliability issues in microsystem technology, methods to understand and predict failure mechanisms at interfaces between dissimilar materials, and an approach to DFR based on deep understanding in materials science, rather than on the use of mechanistic tools, such as FMEA."
