Paper Abstract

The impact of two different quartzglass materials, electric fused (E-material) and flame fused (F-material) on silicon and silicon devices has been investigated, by performing a test process consisting of oxidation, well drive-in and gate oxide. Thereby silicon wafers had direct contact (boat-simulation) and proximity contact (tube-simulation) with the quartz. Metal contamination induced defects have been evaluated using photocurrent imaging (Elymat) for bulk recombination centers and near-surface precipitates together with E-ramp breakdown on gate oxides. The results of both tests indicate a significantly lower impact of flame fused quartzglass material on bulk as well as on surface of silicon and properties of silicon and silicon test devices.
