What is a 1D layout? Surely it must be something of a misnomer, as the only way I can visualize it is as a barcode, where each material you place has to span the entire width of the chip - and that seems utterly worthless.
- Panoramix 10y agoSome high end processes only allow you to pattern a bunch of parallel, narrow lines (hence 1D). These are subsequently "cut" in a useful way, and you can connect to them using a different layer above or below.
