SiOxNy deposition (IBD)

These are some old (2010), initial characterizations only. A recipe improvement would be to increase the Assist O2+N2 = 60sccm total, increasing repeatability. Contact Demis for more info.

Standard Cleaning Procedure (IBD)

You must edit the "#_GridClean"("#" is your group number) steps in your Process according to the following times:

  • 5min GridClean for 1hr or less deposition
  • 10min GridClean for up to 2hrs of dep.
  • Do not deposit for longer than 2hrs - instead break up your Process into multiple 2-hr subroutines with cleans in between. See the recipe "1_SiO2_Dep_Multi" for an example.
