Some of the Metelics GaAs diodes get down there. Their silicon parts
get below 0.1 pF.
M-pulse gets down to about 0.06 pF, chip or beam lead.
HP/Agilent used to sell some 0.03 pF parts, but I'm not sure if they
still make them.
Yup, this one is obsolete:

Macom has some beam-lead 0.05 pF parts, probably expensive.
What are you working on?
