This is all you need to build simple transistors and IC's at your home. This picture was taken at the Think conference by a good friend.
We spent the weekend making solar cells, single transitors(fets), pmos inverter(resistive load) and a full CMOS inverter.
To the left you can see the nitrogen gas bottle, some cassettes of wafers, toward the middle the linberg furnace and test equipment to the right.
