I am looking for instructions for a peanut butter and jelly fab. Have never done the workshop myself (otherwise I'd have the instructions) but have heard it described several times over. Last night I heard it in gory detail for the first time. It sounds like a nice compliment to basic circuits, assuming you have some knowledge of IC manufacturing. It would be heresy to mix up the various oxide layers and get the reticle wrong.
I tried Googling variants of this phrase only to find many peanut butter aficionadoes and sellers of various baked goods and snacks. I found detailed instructions for the cookie fab, which is not the same thing.
The idea behind the cookie fab is to demonstrate IC manufacturing with cookies. A sugar cookie is the wafer. Frostings are oxide layers, and sprinkles are dopants. Etching steps require brushes and plastic knives which must be decontaminated and isolated to prevent cross-contamination.
With the PB&J IC is you start with a large cracker as your wafer. The first layer of peanut butter is oxide. Jelly forms the reticle. You use your finger as the etch step, already making this workshop superior to the cookie fab. Then you must remove the reticle, and apparently the most effective way is to lick it off. I would imagine there are sprinkle, chocolate chip, or raisin dopants, but the description kind of stopped at etch.
On the plus side, peanut butter is much healthier than frosting.
