      FSM 900TC-Vac systems measure the radius of curvature by a laser triangulation technique which is represented by the schematic shown below. As the wafer is moved below the laser beam, the beam is deflected according to its curvature. The system determines the position z of the beam with a photodetector as a function of position x.<\/p>

      From the measured data, the radius of curvature is calculated using the formula shown in Eq. (1). R is the radius of the curvature, L refers to the beam path distance from the wafer surface to the detector. Knowing the beam path, the radius of curvature can be determined from the slope of a dz vs. dx plot. The bow height H of a wafer with diameter D can be calculated using

      Stoney\u2019s equation (3) gives the relation between the stress and the radius of curvature of the stressed wafer:

      Where, E is Young\u2019s modulus, Ts is substrate thickness, Tf is film thickness, \u03bd is Poisson ratio, and R is a curvature of stressed wafer. E\/ (1-\u03bd) is defined as the stress constant. For Si 180.5GPa is used in the following. The above equation assumes that the unstressed substrate is perfectly flat. In practice the stress is calculated using the change in bow height relative to the bare substrate. In this study we only show the measured bow height as a function of temperature. The measured \u2018bow height\u2019 displayed is a fit of the data taken across the entire wafer to a perfect sphere.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      Rapid Thermal Mechanical Characterization of Low K Dielectrics, Copper & other Thin Films for Semiconductor, MEMS, Solar, LED, and FPD Applications (upto 900\u00b0C)<\/h5>

      Why Vacuum Annealing Chamber?<\/strong><\/h4>

      With the drive towards smaller line width and higher speed devices, process integration will involve new thin film materials like low K, copper and other novel materials. However, several of these new materials are very sensitive to oxidation at elevated temperatures. They are also prone to outgas, or exhibit physical and material changes upon heating.To help characterize these changes, the FSM-900TC-Vac offers sealed heating type chamber that simulates process conditions. It can operate either under a completely inert gas environment (with a very low partial pressure of oxygen) or under high vacuum mode.<\/p>

      Why integrated metrology?<\/strong><\/h4>

      By incorporating multiple probes around this chamber . Stress hysteresis, thermal desorption, film shrinkage and reflectivity changes in the thin film can be simultaneously extracted. This approach overcomes sample to sample and tool variations for new material characterization. By integrating these metrology data, FSM-900TC-Vac can quickly profile the thermal stability and thermal loading capacity for new materials. For example, the type of material outgassing at specific temperature can be correlated or overlaid graphically with data from film thickness\/shrinkage, reflectivity and stress hysteresis profiles. Probes are also available to study resistivity changes from monitoring grain growth or phase changes. This novel integrated metrology approach can dramatically speed up new material screening and help compress the process integration cycle at the various technology nodes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
