<I still don't believe that's nano, in the sense that many starry-eyed folks are talking about. > I was sitting out in the garden last week with a particularly clear head... very few thoughts, just watching nature... wrens, quail, bees, trees.... these two cactus wrens came chirping wildly playing chase and gave quite a spectacular air show around and through the big Iron Wood tree. Then I noticed in the sky above the tree a jet-liner trudging by. The message of nature is clear: buy gardens, short [nano] technology! -1/2ggg- DAK

I still don't believe that's nano Maybe, depending on your POV, but it is micro machining in 3D. That article I posted is a mature view of that technology imho. I have not worked on micro machining myself, but in a closely related technology that had 3D structures in it. The link talks about the dirty edge of the technology. For a start if you successfully make a micro machined wafer with thousands of good parts on it, you still have to saw up the wafer into individual chips, or laser scribe or whatever. Trouble is the particles from such an operation can start swilling around the 3D structures and cause problems later. It's a bit like throwing in some extra ball bearings into an already assembled gear box of a new car. That article talks about the potential reliability problems that may result. Normal silicon chips, that just have electrical operation do not suffer as much from this problem. Make 'em smaller, and you have many problems as you like, just smaller. Any lawsuits from non working parts "in the field" such as a human body would be macro sized I would imagine.
