To prevent the dewetting phenomenon of said patterns, lateral oxidized zones are arranged at the periphery of each pattern of the thin film so as to form an anchoring. This anchoring can be achieved by forming an oxide layer over the whole of the thin film and then depositing a nitride layer. Then the nitride and oxide layers and the thin film are patterned and the thin film is laterally oxidized so that each pattern of the thin film comprises, at the periphery thereof, an oxidized zone of predetermined width. The nitride and oxide layers are then removed so as to release the patterns oxidized at their periphery.

Thus, a time period required for laser crystallization can be reduced to make it possible to increase a processing speed for a substrate.

Abstract: Slim spacers are implemented in transistor fabrication. More particularly, wide sidewall spacers are initially formed and used to guide dopants into source/drain regions in a semiconductor substrate. The wide sidewall spacers are then removed and slim sidewall spacers are formed alongside a gate stack of the transistor. The slim spacers facilitate transferring stress from an overlying pre metal dielectric (PMD) liner to a channel of the transistor, and also facilitate reducing a resistance in the transistor by allowing silicide regions to be formed closer to the channel. This mitigates yield loss by facilitating predictable or otherwise desirable behavior of the transistor.
