IR-2100, IR-2200, IR-2500, IR-3200

Extended wavelength model-based infrared reflectometry with high throughput, low COO, non-contact, non-destructive measurements of thickness and uniformity of dielectric layers and etched structures used in integrated circuit manufacturing. The unique technology and analysis capability of the IR product line, simplifies system calibration requirements and removes the effect of substrate variations for key layer measurements.
