摘要： An ellipsometric apparatus provides two impinging focused probe beams directed to reflect off the sample along two mutually distinct and preferably substantially perpendicular directions. A rotating stage rotates sections of the wafer into the travel area defined by two linear axes of two perpendicularly oriented linear stages. As a result, an entire wafer is accessed for measurement with the linear stages having a travel range of only half the wafer diameter. The reduced linear travel results in a small travel envelope occupied by the wafer and consequently in a small footprint of the apparatus. The use of two perpendicularly directed probe beams permits measurement of periodic structures along a preferred direction while permitting the use of a reduced motion stage.

摘要： An apparatus for characterizing multilayer samples is disclosed. An intensity modulated pump beam is focused onto the sample surface to periodically excite the sample. A probe beam is focused onto the sample surface within the periodically excited area. The power of the reflected probe beam is measured by a photodetector. The output of the photodetector is filtered and processed to derive the modulated optical reflectivity of the sample. Measurements are taken at a plurality of pump beam modulation frequencies. In addition, measurements are taken as the lateral separation between the pump and probe beam spots on the sample surface is varied. The measurements at multiple modulation frequencies and at different lateral beam spot spacings are used to help characterize complex multilayer samples. In the preferred embodiment, a spectrometer is also included to provide additional data for characterizing the sample.

摘要： A method (100) of fabricating an electronic device (200) formed on a semiconductor wafer. The method forms a dielectric layer (226) in a fixed position relative to the wafer, where the dielectric layer comprises an atomic concentration of each of silicon, carbon, and oxygen. After the forming step, the method exposes (118) the electronic device to a plasma such that the atomic concentration of carbon in a portion of the dielectric layer is increased and the atomic concentration of oxygen in a portion of the dielectric layer is decreased. After the exposing step, the method forms a barrier layer (120) adjacent at least a portion of the dielectric layer.
