You should probably do me the courtesy to not make assumptions about what I've read and understood. This is such a common trope on HN that it made it into the guidelines.
The whole idea that the collapse of civilization is something slow is a massive assumption, it could be all over in a few microseconds so fiddling around with tech at a level like this is an exercise in futility: if this is the level that you end up at that's pure luxury and proof that civilization has not collapsed and likely will not collapse in the near future.
Microchips are not going to be much use in any situation where they can no longer be produced. They are the pinnacle of a very large pyramid and without the base the tip is next to useless.
A better - and far more immediate - use case would be to target the re-use of scavenged chips in the present day undeveloped parts of the world which are 100% dependent on imported goods.
