Unaxis deposition - 300nm SiO2 LDR film @250°C
a) Prepare three 4” wafers:
for seasoning (regular Si wafer ~500nm thick)
for deposition (your wafer for deposition)
for cleaning ( Si thick wafer~0.8-1um)
b) Load all wafers in a cassette, making sure major flat is facing outside (toward you). Try to align flats for all three wafers.
c) Edit standard recipes (for seasoning, deposition, and cleaning). You can ONLY change the time in recipes.
Seasoning recipe name: SiO2 seasoning, t=2min Deposition recipe name: SiO2 LDR 250°C, t=780 sec Cleaning recipe name: Post dep PD, t=900sec There is only one SiO2 seasoning recipe. This same recipe is used for seasoning for both LDR and HDR depositions. The goal in this step is to prepare the chamber and deposit ~200nm of SiO2 on walls.
d) Run the job (name the job/select the wafer, execute the job)
After loading the wafers and selecting for each wafer correct recipe, you could leave and come back when all runs are finished. You should monitor process at the very beginning to make sure there are no any issues with the run.
e) Unload wafers ONLY when all runs are finished.
Unaxis deposition - 300nm SiO2 HDR film @250°C
a) Prepare three 4” wafers:
for seasoning (regular Si wafer ~500nm thick) for deposition (your wafer for deposition) for cleaning ( Si thick wafer~0.8-1um ) b) Load all wafers in a cassette, making sure major flat is facing outside (toward you). Try to align flats for all three wafers.
c) Edit standard recipes (for seasoning, deposition, and cleaning). You can ONLY change the time in recipes.

Unaxis deposition - 300nm SiN film @250°C
a) Prepare three 4” wafers:
for seasoning (regular Si wafer ~500nm thick) for deposition (your wafer for deposition) for cleaning ( Si thick wafer~0.8-1um) b) Load all wafers in a cassette, making sure major flat is facing outside (toward you). Try to align flats for all three wafers.
c) Edit standard recipes (for seasoning, deposition, and cleaning). You can ONLY change the time in recipes.
Seasoning recipe name: SiN seasoning, t=5min Deposition recipe name: SiN 250°C, t=480 sec Cleaning recipe name: Post dep PD, t=1500sec d) Run the job (name the job/select the wafer, execute the job)
After loading the wafers and selecting for each wafer correct recipe, you could leave and come back when all runs are finished. You should monitor process at the very beginning to make sure there are no any issues with the run.
