Robert, Re: "The tool that Anand mentions (Focused Ion Beam) isn't exactly proprietary, it's made by another Oregon company named FEI Company (Ticker FEIC) I have been invested in this for several years and have never been able to drum up any interest in the FEIC board here at SI. My personal feeling is that FIBs are an idea whose time has come. <tout, tout> So if anyone is interested:" FIBing parts is a useful and necessary tool with validation, as it takes a much shorter amount of time to verify a fix on current silicon than it does to spin a new stepping in the fabs. However, moving the technology past validation to make it a high volume product has absolutely no use. Can you imagine FIBing a million production parts per week? wbmw

"My personal feeling is that FIBs are an idea whose time has come." I am afraid you are wrong. FIB tools are everywhere, almost everyone and their dog has it, and you can buy their services relatively cheap. But their time is over IMO. FIBing is the last resort to proceed with a piece of silicon that failed because of poor design and verification techniques (and faulty or misused layout/tapeout tools). In a normal, successful design environment the FIB technique should never be used. More, with deep submicron feature sizes and 6+ layers of metal interconnect, the FIBing capabilities almost vanish, if you see the trend. - Ali
