[From the last episode: we looked at different ways of removing material from a wafer.] So far we’ve seen that we can add materials to a wafer and we can remove them. But, if those are our only tools, then it’s not particularly useful, since we’re covering a whole wafer […]

[From the last episode: Building chips starts with a silicon wafer. From there you add and remove material with the assistance of photolithography.] This week’s piece is about what we called deposition in last week’s edition. “Deposition” actually means something more specific when processing silicon wafers, so, for the moment, […]
