Caution to ALL USERS:
Both the Std. sample holder and now the Universal Sample Holder USH) are not landing
onto the piezo mounts correctly. We are measuring ~ 0.770 - 0.880 mm total delta working
distance across a 100 mmm wafer -- when it should be less than 0.124 mm on the std.
sample holder and less than 2 um on the USH.
Users are requested to reply if they encountered a stage or loading sample holder crash
or misfortune during their operations over the last two weeks.  
Users writing on the system the last two weeks are requested to carefully inspect their
patterns before pattern transfer to confirm their CD's are to specifications.  Please
report to the raith@snf.stanford.edu list your observations.
Immediate field service request has been from RAITH USA Inc.
Thank you,
JWC
