Im looking to optimize a low stress silicon nitride process for a film 1 to 2 µm thick, residual tensile stress of 50MPa with no or low pinhole density. Wafer sizes are 100 to 200 mm. Are there any trade-offs between stress and pinhole density for any given DCS:NH3 ratios, boat position, temp, pressure or total gas flow? Thanks, Anthony Marrs Intellite
