New blogs examine the future of NAND flash memory, a preview of the International Electron Devices Meeting (IEDM) – is it time to think about the end of silcon? – Skyworks’ use of SOI, the Sony ISX014 8MP sensor, MEMS and the Internet of Things, and The ConFab, which will be held June 22-25, 2014 in Las Vegas.
New blogs take a look at design challenges associated with re-filling an engineering change orders (ECOs), this year’s ISS meeting, and the pervasiveness of cheap silicon.
New blogs take a look at recent reports from G450C showing good results for major process steps and inspection (although cost benefits remain to be proven), new FD-SOI results demonstrating a 10X faster DSP, the need for high sigma yield brought on by the move to 28/20nm and 16nm, Obama’s policy impact on the semiconductor industry, the recent IEEE 3D IC and GaTech Interposer meetings, and the latest nanotechnology-use survey from NCMS.
New blogs examine cooling 3D IC stacks and the role of DARPA’s ICECool program, what was going in 50 years ago in January of 1964 as viewed through the pages of Solid State Technology, and design for test requirements of safety critical applications such as those of automobiles.
New blogs cover SoC design with system level functionality, 3D system integration, fixing litho hotspots, packaging design with the database diary, and why mobility is the new industry driver.

The increasing demand for wireless data bandwidth and the emergence of LTE and LTE Advanced standards pushes radio-frequency (RF) IC designers to develop devices with higher levels of integrated RF functions, meeting more and more stringent specification levels. The substrates on which those devices are manufactured play a major role in achieving that level of performance.
Everybody’s talking about it, but just what is DFM? According to various EDA company websites, design for manufacturing can be: generation of yield optimized cells; layout compaction; wafer mapping optimization; planarity fill; or, statistical timing among other definitions. Obviously, there is very little consensus. For me, DFM is what makes my job hard: Characterizing it, and developing tools for it, is the most important item on my agenda.
In nanometer designs, the number of single vias, and the number of via transitions with minimal overlap, can contribute significantly to yield loss. Yet doubling every via leads to other yield-related problems and has a huge impact on design size. While there is still concern over of how many vias can be fixed without rerouting and without creating DRC violations, the Calibre via doubling tool can identify via transitions and recommend areas for second via insertion without increasing area.
Certain measurement methodologies can be inaccurate even if they’re precise, and there are known errors associated with certain system parameters.
