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). |

Some users have experienced issues with column alignment when using Au ions. Raith service will be onsite today and tomrrow to make adjustments. I'll run checks and calibrations over the weekend. I expect the Raith Velion to be available again on Monday morning (Sept 16th). I'll send further updates if anything changes. |

When the vendor came in to install the new top heater he wasn't able to get the z-axis (elevator motor) to move. He was able to install the new heater and do a PM on the rest of the tool. We are ordering a new z-axis controller on the recommendation of the vendor. If all goes well this should solve the issue and make the bonder fully operational. I'll send out an email once the new controller has been installed. |
