The chapters in this edited book are written by some authors who have presented very high quality papers at the 2015 International Symposium of Next-Generation Electronics (ISNE 2015) held in Taipei, Taiwan. The ISNE 2015 was intended to provide a common forum for researchers, scientists, engineers, and practitioners throughout the world to present their latest research findings, ideas, developments, and applications in the general areas of electron devices, integrated circuits, and microelectronic systems and technologies. The scope of the conference includes the following topics: A. Green Electronics B. Microelectronic Circuits and Systems C. Integrated Circuits and Packaging Technologies D. Computer and Communication Engineering E. Electron Devices F. Optoelectronic and Semiconductor Technologies The technical program consisted of 4 plenary talks, 23 invited talks, and more than 250 contributed oral and poster presentations. Plenary speakers were recognized experts in their fields, and their talks focused on leading-edge technologies including: "The Future Lithographic Technology for Semiconductor Fabrication" by Dr. Alek C. Chen, Asia ASML, Taiwan. "Detection of Single Traps and Characterization of Individual Traps: Beginning of Atomistic Reliability Physics" by Prof. Toshiaki Tsuchiya, Shimane University, Japan. "The Art and Science of Packaging High-Coupling Photonics Devices and Modules", by Prof. Wood-Hi Cheng, National Chung-Hsing University, Taiwan. "Prospect and Outlook of Electrostatic Discharge (ESD) Protection in Emerging Technologies", by Prof. Juin J. Liou, University of Central Florida, USA. After a rigorous review process, the ISNE 2015 technical program committee has selected 10 outstanding presentations and invited the authors to prepare extended chapters for inclusion in this edited book. Of the 10 chapters, five are focused on the subject of electronic devices, and the other covers the circuit designs for various applications. The authors are working at the academia in Austria, United States, Korea, and Taiwan. The guest editors would like to take this opportunity to express our sincere gratitude to all the members of the ISNE 2015 technical program committees for reviewing the papers and selecting the manuscripts for the edited book. We also thank all the authors for their valuable and excellent contributions to the book.

In recent years, many efforts have been devoted in the study, development and application of Green Photonics and Smart Photonics. This book presents recent advances, both theoretical and applications, reflecting the cutting-edge technologies and research achievements within these research fields.Green Photonics intend to develop photonics technologies that can conserve energy, reduce pollution and create renewable energy. Light emitting diodes (LEDs) and solar cells with the characteristics of sustainable and low energy consumption are addressed in this book. The term of Smart Photonics reflect intelligence of optical and optoelectronic components with high sensitivity, fast response time and/or compact size. The book explores various aspects ofsmart photonics including fiber sensors, optoelectronic devices and waveguide devices. The chapters in this edited book are written by researchers who presented quality papers at the 2015 International Symposium of Next-Generation Electronics (ISNE 2015), which was held in Taipei, Taiwan. The ISNE 2015 provided a common forum in the areas of opto-electron devices, photonics, integrated circuits, and microelectronic systems and technologies. The technical program consisted of 5 plenary talks, 23 invited talks and more than 250 contributed oral and poster presentations. After a rigorous review process, the ISNE 2015 technical program committee has selected 10 outstanding presentations and invited the authors to prepare extended chapters for inclusion in this book. Of the 10 chapters, five focus on the subject of green photonics, and the others cover smart photonics.
