The recipes below are given as starting points from data obtained in the nanofab. For critical depositions, calibrations are recommended. Please see the [https://signupmonkey.ece.ucsb.edu/cgi-bin/users/browse.cgi?tool_ID=20 SignupMonkey Page] for a list of currently installed targets.

===Tips & Tricks===

====Ignition Issues====
It is somewhat common that you might have a plasma ignition failure at some point. Common remedies for this are to increase the chamber pressure just for the ignition step, then drop dow to the process pressure in the PreClean and/or Dep step. For example, set the ignition step pressure to 10mTorr or 30mT, then during deposition decrease the pressure to 3mTorr and the plasma will stay lit.

Sputter 3 (AJA ATC 2000-F)

Please see the SignupMonkey Page for a list of currently installed targets.

Tips & Tricks

Ignition Issues

It is somewhat common that you might have a plasma ignition failure at some point. Common remedies for this are to increase the chamber pressure just for the ignition step, then drop dow to the process pressure in the PreClean and/or Dep step. For example, set the ignition step pressure to 10mTorr or 30mT, then during deposition decrease the pressure to 3mTorr and the plasma will stay lit.

Materials Table (Sputter 3)

The recipes below are given as starting points from data obtained in the nanofab. For critical depositions, calibrations are recommended.

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 by getting away from the low-flow limit of the MFC's. Data provided by Demis D. John, 2010.

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.
