Notes

Substrates RCA cleaned.
Si(100) substrates HF dipped for diffusion barrier measurements.
Resistivity decreases with increasing plasma power, increasing plasma time, and increasing film thickness.
Reference 11 might be a good read to compare different thin film thickness measurement techniques.
