Substrates

SiO2

Notes

SiO2 pirahna cleaned.
Samples annealed at 450, 500, and 550C for one hour. 450 and 500C annealed samples remained amorphous. 550C annealed sample crystallized.
Hole sidewall and top surface have same C impurity % for PEALD films. MOCVD film with post-dep plasma treatment had higher %C on hole sidewalls compared to top surface.
