Multipurpose Anneal furnace acceptance test

The acceptance for the Multipurpose Anneal furnace was performed in November 2014 by ATV Technologie and DTU Nanolab.

At the acceptance test a dry oxide layer was grown on a boat of 150 mm wafers. The oxide growth was repeated three times

For each run the oxide thickness and refractive index were measured on three of the wafers, and the standard deviation and non-uniformity were calculated for each wafer, over the boat and from run to run.

Oxidation parameters

Recipe: "vr_dryOx_1000C_120min_150_5Wafer_D1_mit_Inliner_oPurgering.ATV"

Oxidation time: 80 min

Temperature: 1050 oC (all temperature zones)

O2 flow: 1 slm

The oxidation has been done with 150 mm wafers. The number of wafers in the boat was 30.

Wafer 4 (towards the door), wafer 16 and wafer 28 (towards the service area) were measured in 13 points using the M-2000V ellipsometer.
