Has anyone looked into making MEMS on the chip? I've seen a few logos and so forth, wondered if anyone had done actual mechanisms? The tricky part, I'd guess, is making parts that deliberately detach from the surface and really honestly won't come loose later.
@v - The idea with providing the ability to purchase full wafers is to allow people to add further layers on top of the GF180MCU stuff. I added that as it was requested by a bunch of groups but so far nobody seems to have actually used it.
Yeah, you also need to do weird stuff like depositing on top of resist, etching holes, then washing the resist out from underneath. Not typical process steps...
