Making a chip is a long and tedious process. We, programmers, often abstract the hardware running our codes. And that’s a good thing. Few of us, thrive at the junction point between the hardware and the software. At this level, you have to think about how a line of code is translated by the compiler, and how those instructions are executed by the hardware, so you can squeeze the last drop of performance and efficiency. At this scale, you think branch predictor, pipeline, cache line or execution engines. And every new program is a fascinating challenge! But there are more layers below this line that a programmer cannot reach. It is the realm of the transistors and the energy particles used to manufacture them. Today, I decided to share a few pics to show the complexity and the beauty of the chips we need to run our modern societies. On the wafer – the gold-ish pictures –, you may notice a tinny black dot on some of the chips. These are the failing ones. To engrave these circuits, when photolithography is used, you need several masks to define the patterns required to build the silicon circuitry (and a lot of chemistry as well). The mask shown here is made of quartz. Although these chips and the mask are old-tech compared to the state of the Art, it was impossible to take pictures that tributes their finesse. At least I tried ;-). Have a great WE!

Cerberus Rabbit in some way, it is already 3D printing – though you do not deposit really the materials from print heads, you grow and infuse them really. That put aside, there are two points you would have to solve if you want it to be viable. You would need to print with the right materials to have a functional transistor (with the right performance), and then, the scale. Extreme UV is used to reach the 10nm feature size today. You would need 3D printer with a resolution hard to achieve today (though when you see what they can do with MEMs :)).
Cerberus Rabbit Well, life proved us that we should not say never 🙂 So, who knows in the future what could be done. Probably some low-scale integration circuits first before a full fledged CPU 🙂
i make chips for a living. it’s a fascinating process.
Pretty cool project. With few interesting comments toward the end about scale, programmer perception, architecture and retro computing. I thought it could de an interesting ADD to the discussion.youtube.com – MegaProcessor – Computerphile
