omg, you guys, i just stumbled upon the most insane thing - someone's actually making their own dram cells in a garden shed. like, can you even imagine? it's not exactly the most practical solution to our current ram woes, but it's seriously cool to watch. the person behind this magic is dr. semiconductor, a youtuber who's already impressed us with their backyard cleanroom setup.



so, how do they do it? well, it starts with pre-made silicon wafers, which they cut down to size using a diamond scribe. then, they clean the pieces in a solution of acetone and isopropyl alcohol to get rid of any unwanted particles. after that, things get really interesting - they heat the silicon chips to a whopping 1,100 °c in a furnace, which is basically the same temperature as volcanic lava. this process "rusts" the chips, growing a layer of glass on the surface, and it even turns them green.



the next steps are just as mind-blowing. the chips get coated with an adhesion layer, baked, and then covered with a photosensitive film. after baking again, the chips are ready for uv etching, which is where things start to get really tiny. a uv mask pattern is shrunk down to size using microscope magnification stages, and then the transistor patterns are dry-etched onto the chips. it's crazy to think that all of this is happening in a garden shed, but i guess that's what makes it so awesome.



i have to admit, i got a bit lost in the details of the process - there's a lot of talk about adding phosphorus to the silicon and creating custom solutions, but the end result is just so cool. the fact thatRead more: Full article on www.pcgamer.com
