Dope with boron

The furnace A2 boron predep can be used to predeposit silicon wafers with boron. The silicon wafers are positioned in a silicon carbide boat just next to wafers of boron nitride. Boron is predeposited on the silicon wafers. -Rune, hvad er det der sker?

The concentration of boron in the wafer depends on the process temperature. The depth profile depends of the process time.
