Held in Sao Paulo, Brazil, from September 6 - September 9, 2010, the mission of the 25th Symposium on Microelectronics Technology and Devices ¿ SBMicro2010 was to share ideas and to point to new directions for future research and development. SBMicro offers researchers and practitioners a unique opportunity to share their perspectives with those interested in the various aspects of microelectronics. This issue of ECS Transactions continues the SBMicro tradition of being a premier forum for the presentation of leading edge research on process, devices, sensors and integrated circuit technology.

ISTC/CSTIC is an annual semiconductor technology conference covering all the aspects of semiconductor technology and manufacturing, including devices, design, lithography, integration, materials, processes, manufacturing as well as emerging semiconductor technologies and silicon material applications. ISTC/CSTIC 2009 was merged by ISTC (International Semiconductor Technology Conference) and CSTIC (China Semiconductor Technology International Conference), the two industry leading technical conferences in China, and consisted of one plenary session and nine technical symposia. This issue of ECS Transactions contains 159 papers from the conference.
