Introduction to Microfabrication
In the Bosch process (named after the company which developed it) SF6 and
C4F8 gases are pulsed: an SF6 pulse etches a few micrometers of silicon, but
etching is not completely anisotropic. A C4F8 pulse is then applied, and a ...

Amines: Synthesis, Properties and Applications
In 1913 the world consumption of fixed nitrogen was around 7(K) (HK) tonnes,
and by 1929 it had trebled to around 2.1 million tonnes, of which the Haber-
Bosch Process accounted for just less than half of the total, as shown in the data
below.
