Most commercial grade IC's are plastic encapsulated, not ceramic. A lot of IC's are available from the manufacturer packageless, as raw die. The cost differential is not substantial. The plastic encapsulation provides protection from mechanical damage to the die and encapsulates the bonding wires that allow a more macroscopic connection to the outside world. Epoxy cure time (baking at ~85 deg C) is often something a line manager will cheat on to bring up profits.

I don't believe there is any such animal, even on the drawing board....or if its even theoretically possible. No?
