Default Re: OMY - what are these devices?

Hmm, now what is the definition of an IC?

The word 'Microcircuits' gives a sense of scale without saying whether it is a construction on alumina or FR4, or all in one piece of silicon.

'Hybrid' says that the active devices aren't of the same lump that acts as the substrate.

'Monolithic' says that everything, substrate, devices etc are made from one lump of whatever it may be.

'Thick film' hybrids usually means that resistors at least are made by deposition on the surface, and that normally needs a substrate which can survive firing.

I think of real ICs as being monolithics, and then all the rest get fuzzy borders.
