Branch Education walks through a semiconductor fab and the dozens of steps used to turn silicon wafers into microchips, with 3D animation. It covers lithography, deposition and etching at a high level.
Why Hacker News points people here: Pointed to as a clear visual reference for chip manufacturing steps.

The graphic from the OIST in the link makes reference to both the reduced power needed and reduced capital costs, less mirrors & cheaper EUV light source. Also, less power -> less heat -> less cooling. I scoured for some other info as well: A single chip would go through a photo-lithography tool about 80 times. A photo-lithography tool can work on approx. 125 wafers per hour (5 FOUPS). A wafer contains ~230 chips. Current EUV light source requires a 20kw carbon laser. this video link

Shows the manufacturing steps, though not identical to TSMC's

A video showing those steps, for the curious: this video It's probably not 100% identical to TSMC's process.
