This book was released on 2012-12-06 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past years, elliposometry, a non-destructive and contact-less optical surface analysis technique, has gained increased importance in industrial areas, such as the technology of electronic devices, when simple instruments, many of them computer-controlled and automated, became available. The potential users of such instruments are, however, frequently aware neither of the inherent possibilities of this technique, nor of its accuracy limitations. This book endeavors to point out some of the less obvious features and possibilities of ellipsometry, particularly of dynamic "in situ" measurements, and reviews its applications in research and manufacturing of semiconductor and thin film devices. A comprehensive discussion of various error effects typical particularly for simple ellipsometers and of their impact on measured sample parameters is provided. Error correction or (numerical) calibration procedures are given wherever possible, and design and operation guidelines for high-speed instruments suitable for dynamic "in situ" measurements are suggested.

Download or read book Expanded Beam Spectroscopic Ellipsometer for High Speed Mapping of Photovoltaic Materials written by Ambalanath Shan and published by . This book was released on 2017 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of recent advances in photovoltaics technology, renewable energy generated by the sun has become a viable alternative to traditional sources of energy. Photovoltaic modules composed of thin film solar cell devices offer several advantages over standard wafer based silicon modules, including high throughput automated production and reduced materials usage and cost. Spectroscopic ellipsometry (SE) is an important measurement tool capable of aiding high throughput manufacturing processes for thin films. SE is a non-destructive measurement technique well suited to measure and track parameters critical to photovoltaic device performance such as layer thicknesses, as well as optical and electrical properties of the layer components. This dissertation seeks to extend the application of SE via an expanded-beam method to large area photovoltaic modules while retaining the high measurement speeds of single spot measurements with collimated beams. The transition of ellipsometers as laboratory instruments to ones suitable for high throughput manufacturing lines poses unique challenges. The construction of a rotating compensator ellipsometer suitable for industrial applications is addressed with an emphasis on measurement speed. Schemes are evaluated to correct SE data for the inherent misalignments present in large area measurements of full-scale panels. In particular, consideration is given to the problems of oscillations due to compensator misalignment, effects of glass stress and overlap of reflected beams in through-the-glass measurements, and off-plane corrections due to large area substrate curvature. Expanded-beam SE was developed and applied for in situ, high-speed imaging/mapping analysis of spatial uniformity over large area multilayer coated substrates used in roll-to-roll thin film photovoltaics (PV). Slower speed instrumentation available for such analysis applies a 1D detector array for spectroscopic mapping and involves width-wise translation of SE optics over a conveyed substrate surface, measuring point-by-point in a time-consuming process. The expanded-beam instrument instead employs a 2D detector array with no moving optics, exploiting one array index for spectroscopy and the second array index for imaging across a line on a large area sample. Thus, the instrument enables imaging width-wise and mapping length-wise for evaluation of uniformity at the high linear substrate speeds required for real-time, in-situ, and inline analysis for roll-to-roll thin film PV. In this dissertation, the expanded beam technique is employed to study the components of a hydrogenated amorphous silicon (aSi:H) thin film photovoltaic device structure in the Ag/ZnO/n-i-p substrate configuration. The layers were deposited on a flexible substrate mounted on a roll-to-roll cassette. Ellipsometric measurements were performed using an expanded beam spectroscopic ellipsometer capable of simultaneously measuring 41 locations across the width of the substrate to form a line image. Layer thicknesses and optical property maps were constructed from sets of line images generated using ellipsometric analysis techniques. These techniques apply a best fit structural model for the film stack and pertinent optical models for the constituent layers of the device structure.
Download or read book A Practical Guide to Surface Metrology written by Michael Quinten and published by Springer Nature. This book was released on 2020-01-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a genuinely practical introduction to the most commonly encountered optical and non-optical systems used for the metrology and characterization of surfaces, including guidance on best practice, calibration, advantages and disadvantages, and interpretation of results. It enables the user to select the best approach in a given context. Most methods in surface metrology are based upon the interaction of light or electromagnetic radiation (UV, NIR, IR), and different optical effects are utilized to get a certain optical response from the surface; some of them record only the intensity reflected or scattered by the surface, others use interference of EM waves to obtain a characteristic response from the surface. The book covers techniques ranging from microscopy (including confocal, SNOM and digital holographic microscopy) through interferometry (including white light, multi-wavelength, grazing incidence and shearing) to spectral reflectometry and ellipsometry. The non-optical methods comprise tactile methods (stylus tip, AFM) as well as capacitive and inductive methods (capacitive sensors, eddy current sensors). The book provides: Overview of the working principles Description of advantages and disadvantages Currently achievable numbers for resolutions, repeatability, and reproducibility Examples of real-world applications A final chapter discusses examples where the combination of different surface metrology techniques in a multi-sensor system can reasonably contribute to a better understanding of surface properties as well as a faster characterization of surfaces in industrial applications. The book is aimed at scientists and engineers who use such methods for the measurement and characterization of surfaces across a wide range of fields and industries, including electronics, energy, automotive and medical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Ellipsometry is a unique optical technique of great sensitivity for in situ non-destructive characterization of surface (inter-facial) phenomena (reactions) utilizing the change in the state of polarization of a light-wave probe. Although known for almost a century, the use of ellipsometry has increased rapidly in the last two decades. Among the most significant recent developments are new applications, novel and automated instrumentation and techniques for error-free data analysis. This book provides the necessary analytical and experimental tools needed for competent understanding and use of these developments. It is directed to those who are already working in the field and, more importantly, to the newcomer who would otherwise have to sift through several hundred published papers. The authors first present a comprehensive study of the different mathematical representations of polarized light and how such light is processed by optical systems, going on to show how these tools are applied to the analysis of ellipsometer systems. To relate ellipsometric measurements to surface properties, use is then made of electromagnetic theory. Experimental techniques and apparatus are described and the many interesting applications of ellipsometry to surface and thin-film phenomena are reviewed. This reference work is addressed to researchers and students with a strong interest in surface and thin-film physics and optics and their applications. It is a must for libraries in the fields of solid state physics, physical chemistry, electro-chemistry, metallurgy and optical engineering.
