Dope with boron
The furnace A2 boron predep can be used to predeposit silicon wafers with boron. The silicon wafers are positioned in a siliconcarbide 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
