12 Jul 2017 PECVD PECVD back online and new policy for tool cleaning

Dear users,

The PECVD chamber has been cleaned and back online for service.

 

The tool recently experienced more contaminations than previous days. In order to keep the tool in good condition, we would like to enhance the tool policy as following:

1. Each deposition in the PECVD should be no more than 5 minutes. If you need to deposit material for longer time, please break your recipe to serveral runs of 5 minutes.

2. After each deposition, user should run the PECVD chamber cleaning recipe. The cleaning time should be longer than your deposition time. The minimum cleaning time is 120 seconds.

 

Thank you for your cooperation!

11 Jul 2017 Asher New Protocol

Hi All,

Please adhere to the following new protocol when using the asher:

1. The chamber default temperature between jobs will be kept at 30 deg C, rather than 80 deg C. The tool reverts to the 30 deg. C automatically after your recipe ends. You still should program the recipe for the the chamber process temperature to be 80 deg. C to keep the chamber clean from the etch byproduct when you do the etching.

2. If you do longer etch jobs, you should cool off the tool every 60 min. For example, if your etch requires 2h of O2 plasma, do the following:

1. Do 1h of O2 plasma

2. 10min of pumping down without any gas flowing - you can keep the temperature settings unchanged for both the chamber and for the sample stage

3. Do another 1h of O2 plasma.

If you have any questions, please let us know.

 

11 Jul 2017 Parylene Al dish - do not push in too deep

Hi All,

When loading the Al dish filled with parylene into the evaporator, please, do not push in the Al dish too deep. Please, place it so close to the door that the door touches it and presses a bit on it. I beleive that if you put in the Al dish too deep into the evaporator, the temperature there may be too high and cause parylene spitting out of the Al dish, which then has to be cleaned before the next run.
