Hi Adnan
There used to be mask repair laser in the 80's that had real small beam
diameters but I don't remember the supplier name.
There are microscope based laser cutters such as Alessi.
You can try them

Subject: [mems-talk] Laser scalpel

Hello,

Does anybody know of a device like a laser scalpel with beam small enough
(<12 microns diameter) that can remove shorts (~ upto 300 microinches of
gold) between conductor traces on ceramics. LPKF laser and electronics has a
laser scalpel but the beam diameter is approx. 25 microns which is too large
for my application. I am looking for something that will clean up shorts in
gaps that are as small as 12 microns?
