简介:
Spectroscopic ellipsometry (SE) is a powerful technique to precisely measure thin film thickness, determine optical constants, investigate surface and interface phenomenon and many other physical, chemical and optical properties of materials. Angstrom Sun Technologies Inc designs and manufactures high quality spectroscopic ellipsometer systems with various options for different applications. Besides ellipsometer system itself, the advanced analysis software is essential to extract the desired information as above-mentioned, such as thickness, roughness, alloy concentration and dielectric constants. TFProbe 3.0from us offers powerful analysis functions for ellipsometry sensitivity study, photometry / ellipsometry simulation and data regression. Unique but configurable mode allows different users to access different level and suitable for both R&D and production quality control purpose.


Models are specified based on wavelength ranges for different applications. The following graph shows available models for standard configurations. In addition, Model 500 simply covers a range of both Model 100 and 400. Customized products are available with wavelength range extension further down to DUV or Infrared (IR) ranges. Normally:
Model 100 covers a wavelength range from DUV to NIR range up to 1100nm.
Model 200 covers DUV and Visible range.
Model 300 covers Visible range, starting from 370nm to 850nm
Model 400 covers NIR range starting from 900nm typically
Model 450 covers Vis to NIR range, starting from 370nm up to 1700nm typically
Model 500 covers DUV to NIR range, up to 2500nm
Model 600 covers NIR to IR range (1.7um to 17um or 1.7um to 30um)

Wavelength range coverage depends on several factors such as light source, detectors, optics used in system, light delivery method (using fibers or not). Because of these factors, all tools can be customized based on specific application. For example, NIR range can be covered up to 1700nm or 2200nm or 2500nm etc. DUV range can be down to 190 nm.

Background on Ellipsometry:
There are many techniques for characterizing materials, each having its own advantages and disadvantages and each being uniquely able to reveal material properties that other techniques can't access. Spectroscopic ellipsometry (SE) is an optical technique that is particularly flexible in that it can be used to determine the optical and physical properties of a wide variety of thin-film materials. Its ability to do this without contact or damage to the material of interest has seen it become routinely used in R&D laboratories and within manufacturing facilities for monitoring thin film growth and deposition processes.
SE relies on the determination of the polarization state of a beam of polarized light reflected from the sample under characterization. When performing SE measurements, the polarization state is determined at many discrete wavelengths over a broad wavelength range. The change in the polarization state can be traced to the physical properties of the thin film by means of a model. Characteristics such as layer thickness, surface roughness, refractive index (n) and extinction coefficient (k) of the materials can be determined with excellent precision through regression analysis.
The instrument determines two ellipsometry angles Ψ and Δ, which describe the change in the polarization state of the beam upon reflection from the sample. The ratio of the amplitude of the polarization within the plane of incidence (P) to the amplitude of the polarization perpendicular to the plane of incidence (S) is represented by Ψ. The phase retardation between the two polarization vectors P and S is represented by Δ. Changes in Δ and Ψ essentially depend upon the optical constants, n and k, of the layer materials and substrate, physical thickness of the individual layers and surface roughness. A regression analysis allows the determination of these parameters.
SE data for Δ and Ψ are obtained at a number of incident angles in a plane normal to the sample surface and typically at 100-200 different wavelengths for each angle. SE instruments use a white light source and individual wavelengths are selected for detection by either a motor driven monochromator, or a multi-channel detector that can detect many wavelengths simultaneously. Increasing the number of angles and wavelengths at which data are acquired improves analysis precision, especially for complicated epitaxial structures.
