I was just wondering if it is possible to make a printer similar to an inkjet that prints microchip designs. It could print three types of pixels using three materials:
conductive material - i.e. copper n-type material - i.e. silicon crystal doped with phosphorus p-type material - i.e. silicon crystal doped with boron
A transistor would simply be an n pixel, p pixel, and n pixel adjacent to one another. Or, it could be a p pixel, n pixel, and p pixel adjacent to one another.
Anyone know what the major issues are with making something like this? It is probably difficult to make some of those materials function as ink, but it might be possible.
