8 things you didn't know about Electronics

14-02-2014
Recently, the European Commission has posted the MEMO/14/106 with intriguing title "8 things you didn't know about Electronics". The note reported advanced nano-electronics and smart systems referring to novel results of selected FP7 projects. Among presented state of the art R&D projects, the EC note described recent e-BRAINS project results:
 
"Energy scavenging technologies will soon allow us to build pacemakers powered by the heartbeat itself, discarding batteries andextending their in-body usage to tens of years. The e-BRAINS project develops modules the size of a capsule (2-3 cm) which, when implanted in a human heart convert some of the heart's own mechanical movement into power. This means patient no longer needs to be operated on every few years to change the pacemaker's batteries."

New Book

09-02-2012
Handbook_Wafer_Bonding
Handbook of Wafer Bonding
Editors: Peter Ramm , James Jian-Qiang Lu, Maaike M. V. Taklo
 
The focus behind this book on wafer bonding is the fast paced changes in the research and development in three-dimensional (3D) integration, temporary bonding and micro-electro-mechanical systems (MEMS) with new functional layers. Written by authors and edited by a team from microsystems companies and industry-near research organizations, this handbook and reference presents dependable, first-hand information on bonding technologies. 
 
Part I sorts the wafer bonding technologies into four categories ? Adhesive and Anodic Bonding; Direct Wafer Bonding; Metal Bonding; and Hybrid Metal/Dielectric Bonding. Part II summarizes the key wafer bonding applications developed recently, that is, 3D integration, MEMS, and temporary bonding, to give readers a taste of the significant applications of wafer bonding technologies.
 
This book is aimed at materials scientists, semiconductor physicists, the semiconductor industry, IT engineers, electrical engineers, and libraries.

IWLPC Panel Discussion

25-11-2011
Event: International Wafer-Level Packaging Conference - IWLPC, Santa Clara, Nov 4-5, 2011
 
Peter Ramm, Fraunhofer EMFT actively controbuted to the IWLPC Panel Discussion and discussed:
  • 3D-IC integration (TSV-Technology for 3D-integrated ICs) is seen as (too) expensive and because of that delayed to 2015 or later
  • So-called 2.5D integration (Si Interposers) with cost issues too (relatively expensive in comparison to performance achieved) - alternative glass interposer concept presented by Rao Tumalla / GiorgiaTech
  • 3D memory stacks (TSV in periphery) will come soon (2012)
  • Heterogeneous MEMS/IC integration is recognized as one of the key drivers for 3D TSV integration (e-BRAINS !) because TSVs just on densities of global interdconnect level - instead of very high densities for 3D-ICs. Focus on Reliability not on integration density !
