Cleaning CCD's

[Kirk Gilmore]

In response to the "cleaning CCD's" e-mail, I have been
cleaning CCD's routinely for a number of years with no
adverse effects.  We coat our thick devices with a laser
dye solution to improve the UV response and I have found
that cleaning the device before applying the solution is
essential in eliminating contaminants. Immersing the CCD
in a 250ml beaker of warm (~50C) acetone for about five 
minutes and then lifting slowly out at about a 45 degree
angle cleans the device well and leaves no residue marks.
I short out all pins to ground during the wash.
As far as the bonding wire problem goes, I have cleaned
and phosphor coated many devices without losing a bond wire.
The deposition process calls for the CCD to be spun at 1400
RPM for several minutes and I can't recall a bond wire
coming off.
