Abstract

Polycrystalline silicon films on oxidized silicon wafers have been subjected to rapid thermal processing before arsenic or boron ion implantation (pre-implant anneal). The films have then been ion implanted and given another rapid thermal process step to activate the dopant and repair the implant damage. The pre-implant anneal has caused the as-deposited grain size to increase by approximately a factor of ten. After the activation anneal these films have shown a 10 to 100% lower sheet resistance than films which did not receive a pre-implant anneal. The increase in grain size by the pre-implant anneal reduced the grain boundary area and as a result reduced the amount of dopant trapped in the grain boundaries relative to that which was actually inside the grains.
