Stained glass window creation:
1. Turn sand into glass
2. Add impurities to cause desirable properties (colors)
3. Cut and polish glass
4. Repeat as needed to build up final window parts from components
5. Dice and assemble with metal interconnects into final structure
6. Install into windows.

Semiconductor lithography:
1. Turn sand into glass(ish)
2. Add impurities to cause desirable properties (electrical)
3. Cut and polish wafer
4. Repeat as needed to build up to final wafer layer from components
5. Dice and assemble with metal interconnects into final structure
6. Install Windows.
Seems about the same.
