LASER Anneal to Enable Ultimate CMOS Scaling with PMOS Band Edge Metal Gate/High-K Stacks

For the first time, we report on the beneficial result for minimizing the activation thermal budget using LASER anneals with metal-oxide-gate-electrode/high-k dielectric MOSFETs. With LASER activation, EOT for PMOS conductive metal-oxide gated devices is reduced 4-5Aring compared to conventional RTP activation methods leading to more aggressive ultimate CMOS scaling when using a conductive metal-oxide for the PMOS gate electrode
