In this work, the modulation of the SBH of Pd₂Si/p-Si(100) diodes with phosphorus (P) dopants (P-DS) was investigated for future applications in the nMISFET fabrication for the low thermal budget gate-first CMOS. The SBH to electron was lowered to 0.61 eV by using the DS process with P dopants on Pd₂Si/p-Si(100) diodes. Increasing the amount of dopant decreases the SBH to electron of the Pd₂Si/p-Si(100) diodes.
