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



Recipe: "vr_dryOx_1000C_120min_150_5Wafer_D1_mit_Inliner_oPurgering.ATV"

Oxidation time: 80 min Oxidation temperature: 1050 oC O2 flow: 1 slm

The oxidation has been done with 150 mm wafer, and with 30 wafers in the furnace.

Wafer 4 (towards the door), wafer 16 and wafer 28 (towards the service area) were measured.

Results

Run number Resist etch rate [nm/min] Wafer 4 Wafer 16 Wafer 28
Average oxide thickness [nm] St. deviation Non-uniformity [%] Average oxide thickness [nm] St. deviation Non-uniformity [%] Average oxide thickness [nm] St. deviation Non-uniformity [%]
Run 1 109.7 1.0 1.7 107.7 0.9 1.1 106.5 0.8 1.2
Run 2 107.3 1.7 2.4 105.0 1.4 1.7 107.3 0.7 0.9
Run 3 103.6 0.8 1.1 102.6 0.6 1.2 102.2 0.6 1.1
Common Temperature 20 degs, HBC 10 torr, Short funnel, with baffle & 5mm spacers
