Message-ID: I loaded a sampe. CCD image was obviously different from the usual. (The stage holder looked in the wrong position.) I moved the sample holder to the Clip No. 4, and chaged WD to be 5 mm, Then I turned on SEM but it could not work. And then I moved the stage and chenged WD several times, but the movement of the stage was very strange.

A. Std. Sample holder was loaded improperly resulting in a crash and fall off the kinetic piezo mounts of the XY stage upon loading into the system. The front right edge of the Std. Sample holder came to rest on the face of the Y axis LIS mirror with the holder rotated by appox. 30 degrees from correct position. Attempting to acertain if the Piezo mounts or Laser Interferometer mirror have become scratched or damaged as a result. Also rehoming and recalibrating the X Y stage and repeating the checks of the switched travel limits as the Stage approached the LIS mirror. B. Finally there appears to have been a EHT high voltage set trip or an actual FE- Gun arcing event in the gun section and the gun has been down since 0106 hours this morning. Do not know yet how or why this occurred. Expect to have the system beck up by Noon today. It will take about 18 - 24 hours for the Ebeam emission to stabilize and users will see lower beam Currents which will slowly rise through the weekend. I will make final adjustments during my session next Monday afternoon. Users are asked to be vigilent during their operations on the system and call me immediately if they encounter and significant problems. Thank you for your support!

Message-ID: I am attempting to recover the proper stigmator functionality. Currently it is impossible to stigmate within the allowed range of the stigmation functions and the E/O card, if not severely damaged, will have to be recalibrated. I am allowing the FE-GUN to run in over the lunch hour in hopes that this will improve the beam conditions and allow to stabilize in emission before performing the calibration routine on the Magnification amplifier and stigmation centering functions. RAITH and ZEISS have been contacted and a service call is being placed by RAITH USA Inc. Could not reach ZEISS by telephone, no answer...

Message-ID: Good Afternoon: Electron optics board in the RAITH 150 may have been damaged im EHT trip event that occurred early this morning. This trip may have been a result of touching the pole piece cap on the final objective lens during the sample holder crash. They occurred within a minute of each other on the LEOLOG.LOG. I attempted to recalibrate the E/O board mag. amplifier and stigmation offset correction functions but I cannot achieve the larger range of control I need to be able to stigmate well enough to obtain a clear image and perform the calibration. The lens or stigmation quadropoles may have been damaged. Spoke with Zeiss Field service by phone and we may be able to get a service person on site Monday afternoon next week. Until then we are down and off line on the system. No user access to the RAITH or the LEO systems or PC's over the weekend. Thank you, James Conway From jwc at snf.stanford.edu Mon Dec 11 17:19:02 2006 From: jwc at snf.stanford.edu (James Conway) Date: Mon, 11 Dec 2006 17:19:02 -0800 Subject: Raith Status: Monday December 11, 2006 4 PM -- RAITH WILL REMAIN OFFLINE FOR REPAIRS. Message-ID: <457E0386.3090506@snf.stanford.edu> * Greetings Raith Community: RAITH WILL REMAIN OFF-LINE FOR REPAIRS. I DO NOT KNOW WHEN IT WILL COME BACK UP! * On Friday in the early morning a User's error loading the Load Lock Station resulted in the Standard Sample Holder falling off the piezo post during the Load Lock Exchange. The Std. Sample Holder touched the Laser Interferometer Mirror on the Raith's LIS Stage and may have also touched the SEM Objective Lens Pole piece. This resulted in a arcing event through the column to the stage ground from the EHT power supply. This then caused an EHT set point trip (Error 519) and we subsequently lost some functionality of the Electron Optics Board in the focusing and stigmation sections. Zeiss SMT was not able to provide a Field Service technician as expected on Friday afternoon and no one showed up as expected at any point today. The Zeiss office in Thornwood, New York did not deploy a Field Service engineer today as was promised by Zeiss management Friday afternoon. I again spoke with Christoff Barbier, Zeiss west coast service manager and he stated that we could not get a engineer here as they were deployed to Hitachi HTA - Almaden. I have attempted to expedite a Electron Optics board to our site but have not been able to obtain one, likely as in similar situations before they do not have a board in current stock. Zeiss wishes to review the situation before they commit to shipping a E/O board despite my request they come over with E/O and EHT control boards and tools to effect repairs. I have also requested they bring over a final objective lens pole piece cap just in case it too had become damaged during this event. *I must say that I am again very disappointed in the poor service response and lack of effort by ZEISS SMT to assist us with this event in a timely manner.* Now we are entering our 4th day of downtime and they seem unable to respond to our current need for Field Service Support. Will post more information as progress comes to pass. All Users with reservations after WED Noon should maintain their reservations in hope that I can return the system to service. My apologizes for the negative impact upon your work that this downtime has caused during this busy period. Thank you for your support!
