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. |

New Raith EBL: tool up
It appears that the combination of higher beam currents than usual (we did after all upgrade our EBL capabilities for the purpose of higher throughput at much higher beam currents) and the particular (extremely sparse) stitch patterns we use to measure stitch accuracy revealed a subtle limitation in the Fine Focus coil used in their systems (the Fine Focus coil adjusts focal point on the substrate as the beam is deflected around the 1mm field). We are working with the tool designers in Eindhoven as well as the service team in the US to “fix” this issue. However, in the meantime, we understand and recognize the problem sufficiently to address it if it comes up in real day-to-day usage.
We will be signing off on the tool tomorrow morning at which point the tool will be available for general EBL use to our nanofab community. I will be working with a few experienced users in the next couple of days and then will be reaching out to a wider audience to get more of you trained. -- Bill Mitchell // Demis D.
