Melting Microchip Defects May Extend Moore's Law
schliz lets us know about research out of Princeton on melting away defects on microchips using a laser. The new technique, termed Self-Perfection by Liquefaction (SPEL), was published in the May 4 issue of Nature Nanotechnology. Researchers have traditionally approached chip defects by trying to improve the microchip fabrication process, but this eventually reaches fundamental physical limits to do with random behavior of electrons and photons. By focussing on fixing defects, the new method enables more precise shaping of microchip components, and engineers expect to dramatically improve chip quality without increasing fabrication cost. The before-and-after images are remarkable. Here's a diagram of how the process works.
I was imagining a laser doing touchups on really bad places of the chip to remove shortcircuits and stuff like that. But this seems like another step in the process of making chips.
A bit like drying pulp to get paper.
"Whatever made you ask this question?"
People generally ask questions to get answers. You, however, seem to ask questions to make other people feel stupid.
Then you're much more forgiving than most people.
If a chip is designed to run at a certain speed, but manufacturing flaws make it run slower, then it a very real sense the chip didn't work. The fact that it still is possible to use the chip for some things doesn't mean that it's not broken.
I once rode home a bike that had one of the pedals broken off. It took longer than usual, because I was travelling at a lower speed, but by your definition my bike didn't have a defect. In my opinion, a missing pedal is pretty darn broken.
One time I threw a brick at a duck.
