I have seen single sided antistatic adhesive tape which claims to leave no residue from suppliers of ESD equipment. I can also remember seeing semiconductors being manufactured where they use a blue tacky film for holding bare die when they are sliced up into individual circuits from the original disc of silicon. I therefore presume double sided static safe, non-residue tapes are a possibility!
