Sorry to spam all. I have a question for P620B2H6 recipe. I ran this recipe for 40min with B2H6 gas flow 10. The thickness of the polysilicon is 400nm as expected. However, I measured the resistance of the film by using Prometrix, it is around 370 ohm/sq. This result is quite different from the calibrate result on SNF's website (69 ohm/sq). Does anyone know why there is a big difference?
Any comments, suggestions are welcome.
