During thermal curing and subsequent cooling , the residual stress was
measured in situ as a function of temperature over the range of 25 to 400 °C .
Figure 4 illustrates the stresses in the polyimide film on the silicon wafer . After

Wet etch rates of these films were expected to depend on both refractive index (
fluorine content ) and stress . Figure 2 shows that the wet etch rates of undoped
TEOS oxide films increase as the stress is reduced . Figure 3 shows the wet etch
