Dear Yu Chen,


Hello, there are several ways to dope, ion implant, boron solution or
spin-on boron, planar source, Boron gas in the diffusion tube etc.

It seems the easiest is for you to use a boron solution that can be spun
on, brushed on or dip coated. These types of solutions can be obtained from ;
Filmtronics
Butler, Pa.

They have several solutions that can work fine, let them know the
approximate concentration of dopant needed and the temperature you wish to
diffuse at or use RTP.

Hope this helps, if you have any questions please ask.
Sincerely, Neal
