Hexagonal chips when?
- s0rce 2y agoseems hard to dice
- haneefmubarak 2y agoIO OR L4$ triangle tiles, main chip hexagons
- pitaj 2y agoIt would only require double the cuts, right?
- ajb 2y agoThe problem with that is that you can't do it by making straight chord slices of the the wafer - each cut has to terminate or it will go through the middle of the next hexagon. But it does sound plausible - surely lasers could do this more easily than retooling the whole lithography pipeline for rectangular wafers. But you'd think they would have thought of the idea. You could do triangular chips with straight cuts. But I that would divide the area more finely, which is the opposite of what they need.
- azornathogron 2y agoWith chiplet based designs, how big are the individual chiplets? Would triangles make sense in that context? (Asking from total ignorance)
- ajb 2y agoIt varies, if you look at meteor lake [1] the different die go from 27..100 sq mm (Compared to the h200 which is an insane 814 sqmm) But I don't see any obvious advantage to small triangular die. Once the die are small if doesn't make much difference vs rectangular as to how many you can pack into a circle (for a given die area), and rectangle are much more convenient [1] https://en.m.wikipedia.org/wiki/Meteor_Lake https://en.m.wikipedia.org/wiki/Meteor_Lake
- dev_tty01 2y agoI would say never. Hex gives no advantage over round. Both have waste when dicing. Square gives the least amount of waste.
- BitwiseFool 2y agoSquares tessellate better than hexagons so I have no idea what advantage hexagons could bring.
- lawlessone 2y agoIf we're suggesting shapes can I suggest one on the surface of pipe that wraps back around on itself? So I can run coolant through the middle.
- themoonisachees 2y agoI mean. The idea sounds fun but doing photolithography on a pipe's surface sounds like absolute hell.
- ipjrms 2y agoHey, laser printers do it
- themoonisachees 2y agoThat's fair enough.
- HPsquared 2y agoReminds me of Soviet nuclear reactor designs, where the fuel rods were hexagonal (instead of the square Western ones).
