5 tests were made where only the B2H6 flow was changed for each deposition (120sccm,130sccm,140sccm,160sccm,240sccm). All deposition times were 2 min (resulting in 440 nm Oxide). The wafers were annealed in Anneal Oxide Furnace (C1) at 1000°C for 85 min to drive in the boron and the oxide was subsequently etched in BHF. The wafers were then analysed by SIMS and the results are shown in the figure below:
