KLA-TENCOR FLX-2320 SYSTEM CAPABILITIES consisting of:
- Thin-film stress measurement instrument that measures the changes in the
radius of curvature of a wafer caused by the deposition of a stressed thin film.
- Laser scanning to measure stress on all reflecting films.
- Measures and displays stress as a function of time or temperature.
- Comprehensive data analysis capabilities that include trend plotting for
statistical process control (SPC) and displaying a 3-D map of
wafer deflection over the entire surface.
- Used for calculation of biaxial modulus of elasticity and linear expansion,
water diffusion coefficient in dielectric films, linear regression and stress-temp or
stress-time gradients.
- Provides analysis of thin film stress with very low measurement noise and allows
observation and quantitative evaluation of stress relaxation, oxide densification,
thin film phase transformations and annealing.

- NOTE: This system requires the use of reflective substrates to run the
pre/post deposition measurements, transparent substrates will not work.
In most cases customers use Si monitor wafers for stress measurement instead
of product wafers.
