I'm not after quality - I do have an application in mind but it doesn't need to compete with mass production. Just wondering if it's feasible to make something crude that will resonate.

That probably matters in high volume low cost applications. Atmel has the technology for making oscillators. That's an analog-ish corner on what is mostly a digital chip. A lot of their chips are low standby power which generally means an older digital process with thicker oxides that don't leak as much. That probably makes analog corners easier, but I'm far from a wizard at that area. -- These are my opinions.

Hi If you are not to picky, you can buy crystals in bulk for < 5 cents each. Why make them from scratch? Best guess is that in small volume, they will cost you > $20 each to make. Labor cost something ….
