==Standard Cleaning Procedure (PECVD #1)==
===== Thin-Film Properties =====
 
  +
The cleaning procedure is very important in order to have consistent result on this tool and also to keep particulate count low. After each deposition you should clean the tool following instructions carefully. The clean is done in two steps:
   
  +
#Wet cleaning (start cleaning by using a cleanroom wipe sprayed with DI. Wipe chamber sidewalls with it. Finish cleaning by using the cleanroom wipe sprayed with IPA. )

  +
#Load the recipe for cleaning "CF4/O2 Clean" (edit the recipe and change ONLY time of cleaning). Follow instructions regarding a required time for cleaning.

SiO2 deposition (PECVD #1)

SiN deposition (PECVD #1)

Low Stress Si3N4 (PECVD#1)

SiOxNy deposition (PECVD #1)

Standard Cleaning Procedure (PECVD #1)

The cleaning procedure is very important in order to have consistent result on this tool and also to keep particulate count low. After each deposition you should clean the tool following instructions carefully. The clean is done in two steps:

  1. Wet cleaning (start cleaning by using a cleanroom wipe sprayed with DI. Wipe chamber sidewalls with it. Finish cleaning by using the cleanroom wipe sprayed with IPA. )
  2. Load the recipe for cleaning "CF4/O2 Clean" (edit the recipe and change ONLY time of cleaning). Follow instructions regarding a required time for cleaning.

Click the above link for a screenshot of the standard cleaning recipe, for which you will enter a custom time. The recipe is set up so that it will pop up a window for the cleaning time upon running the recipe - you do not need to edit the recipe before running it.

SiO2 deposition (PECVD #2)

SiN deposition (PECVD #2)

Low-Stress SiN deposition (PECVD #2)

Low-Stress Silicon Nitride, Si3N4 (< ±100 MPa)

Amorphous-Si deposition (PECVD #2)

Standard Cleaning Procedure (PECVD #2)

The cleaning procedure is very important in order to have consistent result on this tool and also to keep particulate count low. After each deposition you should clean the tool following instructions carefully. The clean is done in two steps:

  1. (If >29min dep time) Wet cleaning: Start cleaning by using a cleanroom wipe sprayed with DI. Wipe upper chamber sidewalls with it. Finish cleaning by using the cleanroom wipe sprayed with IPA & wiping again.
  2. Load the recipe for cleaning "STD CF4/O2 Clean" (edit the recipe and change ONLY time of cleaning). Follow instructions regarding required time for cleaning.

Standard Clean Recipe (PECVD#2): "STD CF4/O2 Clean"

Click the above link for a screenshot of the standard cleaning recipe, for which you will enter a custom time. The recipe is set up so that it will pop up a window for the cleaning time upon running the recipe - you do not need to edit the recipe before running it.


Clean Times (PECVD#2)

Film Deposited Cleaning Time (Dry)
SiO2 1 min. clean for every 1 min. deposition
Si3N4 1 min. clean for every 7 min of deposition
If > 29min total dep time

(Season + Dep)

Wet Clean the Upper Lid/Chamber

DI water then Isopropyl Alcohol on chamber wall & portholes

ICP-PECVD (Unaxis VLR)

2020-02: New recipes have been characterized for low particulate count and repeatability.  Only staff-supplied recipes are allowed in the tool. Please follow the new procedures to ensure low particle counts in the chamber.
The system currently has Deuterated Silane (SiD4) installed - identical to the regular Silicon precursor SiH4, except that it significantly lowers optical absorption in the near-infrared due to shifted molecular vibrations/molecular weights. This gas is more expensive and thus more applicable to optical application than to general-purpose SiN films.

You must edit the Post-Dep Clean recipe to correspond to your deposited thickness and material. See the Operating Procedure on the Unaxis Tool Page for details.
