Abstract

The present work uses wafer curvature (disk) method to measure the temperature variation of the biaxial modulus and the thermal expansion coefficient TEC from 25°C to 205°C. The following thin films were measured: PolySi, low stress LPCVD SixNy and (Ba0.7, Sr0.3)TiO3 (BST). To improve the precision, perfect circular thin wafers were used: 4 inches circular 280μm thick <111>Si and 450μm thick Fused Silica. The measurements were performed using a commercial Tencor FLX2320 Stress Measurement System. The film thickness was measured with Tencor TF1 thin film optical system.
