Abstract: Techniques for low-temperature ion implantation are disclosed. In one particular exemplary embodiment, the techniques may be realized as a wafer support assembly for low-temperature ion implantation. The wafer support assembly may comprise a base. The wafer support assembly may also comprise a platen configured to mount to the base via one or more low-thermal-contact members, wherein the platen has a heat capacity larger than that of a wafer mounted thereon, such that, if pre-chilled to a predetermined temperature, the platen causes the wafer to stay within a range of the predetermined temperature during ion implantation.
