I would like these diamond samples approved as "Semi-clean".
1) Contact info
Carbon in diamond form
Biocompatible and nonflammable
World's most pure diamond samples. Electronic grade.
Element Six (De Beers)
King's Ride Park, Ascot, UK
Radiation hard, low Z, good thermal conductivity
Wet cleans probably at WBGENERAL with personal quartzware.
Annealing up to 700C for now using Tylan 3
Oxygen plasma using Dryteks
Optical Litho using Karl Suss
Metal deposition(Ti, Cr, Au, Pt, Al) using Innotec or Metalica
I would like this classified as "Semi-clean" for now.
The contaminants are:
10 ppm of Nitrogen
< 1 ppm of Boron
no other significant contaminants
these are special ultra-pure diamonds
stable to over 1100 C - highest meltling point of any material
Once I put metal down it will of course be "Gold" contaminated
and handled accordingly.
Equipment to be used:
Chips with dimensions of about: 5mm x 5mm x 0.3mm (very solid)
I'll remove the material when not processing it.
When finished I'll remove the diamond from the fab.
Please ask if you have any questions about this.
Thanks for your time,
