I work at an open-use lab helping people make microchips of various types.
An issue we come across fairly regularly is that there is no place to ask question on this interdiciplinary, and cutting-edge/complex field. There is a large international community around this kind of work, and we currently ask questions via email, or on some non-ideal sites such as ResearchGate; or here are two questions on Meta SE asking where to ask about this topic: one, two.
Since SE Engineering has a "machining" tag, and that is most similar in scope to a microchip 'fab (I consider a microfab basically a machine shop where you can machine things smaller than a drill-bit), I would like to propose a microfabrication
tag on SE Engineering.
Synonyms include nanofabrication
, and related but not synonyms include microelectronics
(means electronics only, discounting microfluidics or optics), nanotechnology
(often means beakers and chemistry or materials, not wafer-level machining).
Here are some posts that could possibly be tagged "microfabrication". I apologize it turns out there were a lot, and sorry it there are duplicates, this took a good amount of manual search filtering. Not exhaustive, but I was trying to be selective.
