Unfortunately the fix discussed in the last update turned out to be a good news/bad news thing. The good news is that the majority of the field distortion problem we have experienced since the install has been addressed. However the bad news is that there is still a residual settling effect that is distorting the field in one part of the field only and prevents the tool from fully meeting specifications. So it turned out to a layers of an onion kind of thing – because of course it did. |

RF1 continues to be a problem. I will start the process of elimination from a hardware point of view Monday. Once I resolve the hardware issue our Process group will be exclusively running the system for about a week. During this time we will NOT be allowing anyone else to use the system. Sorry for the inconvenience. |

So the suspect now is the fine focus coil in the column (one of the factory engineers predicted stitch shifts when a faulty fine focus coil is present which essentially replicated the errors we are now seeing) and the question now is how to get one of these sent to UCSB. They are a factory install item so for us to get one, and one that has been tested and confirmed to be fully operational, would require it to be taken from a tool currently under fabrication on the production line. |

The dicing saw is scheduled go down for an upgrade on Monday October 9th and will be down for that week and into the weekend. Part of the upgrade will be updated software and will require users to be re-trained. I will provide more info on the re-training once I get a little hands on time with the updated software. |

I went to check the tool out this morning and found it was not pumping down properly. After further inspection of the tool I found that the lid's quartz liner has cracked. Contacting EVG but the tool will probably be down for some time. I will updated everyone once I have an estimated down time. |

We found a blown resistor (and a questionable op amp) on one of the boards that contains the z-axis motor circuit. However, we still cannot get the tool to initialize. Next we will try swapping out the hard drive again and run some more tests. |

I will send out an update once we have one. |

Raith EBL Update
Unfortunately the fix discussed in the last update turned out to be a good news/bad news thing. The good news is that the majority of the field distortion problem we have experienced since the install has been addressed. However the bad news is that there is still a residual settling effect that is distorting the field in one part of the field only and prevents the tool from fully meeting specifications. So it turned out to a layers of an onion kind of thing – because of course it did.
So the suspect now is the fine focus coil in the column (one of the factory engineers predicted stitch shifts when a faulty fine focus coil is present which essentially replicated the errors we are now seeing) and the question now is how to get one of these sent to UCSB. They are a factory install item so for us to get one, and one that has been tested and confirmed to be fully operational, would require it to be taken from a tool currently under fabrication on the production line.
