Scatterometry is a novel metrology approach for process control that has recently been gaining more momentum in microlithography applications. The method can simultaneously measure Critical Dimension (CD), Side Wall Angle (SWA), and thickness of more than one layer. It analyzes the scattered and diffracted light from a periodic array of lines or holes that represent the surface structure of the measured sample. Scatterometry provides a non-destructive technique offering high precision and stability along with high tool-uptime performance. As such, it offers an excellent approach for real-time high volume production control with significant advantages as compared to traditional technologies such as CD-SEM and Profilometry. As the structure dimension shrinks considerably, producing high precision results becomes more critical. To date, reports on the deployment of scatterometry in real production environment have focused on Front End of Line (FEOL) applications such as STI and Gate. However, Back End of Line (BEOL) process control has not been widely reported. In this work, we will discuss the results of our study specifically for metal trench and contact layer on both patterned and etched wafers for 65nm technology node. We will also report the comparison between Scatterometry results to Critical Dimension Scanning Electron Microscope (CD-SEM) and Atomic Force Microscope (AFM). Finally we will provide a statistical analysis of our scatterometry results including precision, fleet precision, and TMU analysis. In contrast to the relatively simple stacks that comprise a FEOL structure, BEOL layers are typically complex structures with a large number of underlying layers. Generation of simulated scatterometry signatures that constitute a reference library for complex structures can require long computational times and result in large file sizes. To mitigate the computational overhead, it is necessary to intelligently decide which parameters to fix and which to vary. An additional complication is presented due to similarities in the optical properties of BEOL stack materials, which can introduce potential for parameter cross-correlation in the measurement. We will discuss methodologies for optimally selecting parameters to be fixed or varied to minimize these effects.

Read Abstract +

Scatterometry is a novel optical metrology that has received considerable attention in the silicon industry in the past few years. Based on the analysis of light scattered from a periodic sample, scatterometry technology can be thought of as consisting of two parts known as the forward problem and the inverse problem. In the forward problem, a scatterometer “signature” is measured. The signature is simply the measured optical response of the scattering features to some incident illumination, like laser light. In the inverse problem, the signature is analyzed in order to determine the parameters (such as linewidth, thickness, profile, etc) of the scattering features. Typically a rigorous electrodynamic model is used in the solution to the inverse problem, but due to the complexity of the model there is no direct analytic solution. Instead, a variety of numerical methods to solve the inverse problem have been proposed and utilized. The earliest widely used method of solution to the inverse problem involved the generation of a “library” of scatter signatures corresponding to discrete parameter combinations of the structure being measured. Once the library was generated, it was then searched in order to determine the best match to the measured signature. The parameters of the best match were then reported as the parameters of the measured signature. As the technology matured, other methods such as model optimization techniques also emerged. In fact, a variety of alternate techniques have been explored and reported, but a general study comparing the results (and hence the strengths and weaknesses) of the various techniques has yet to be performed. In this research, we shall report results from using several different solutions to the inverse problem on two applications (patterned resist and etched poly). The solution methods shall include the classic library search method as well as three common optimization methods. The results will show that each technique has strengths and weaknesses. For example, the library search methods are generally the most robust but also the most time consuming, and the optimization methods, while fast, are prone to reporting a local but not global minima.

The ability to accurately, quickly and automatically fingerprint the lenses of advanced lithography scanners has always been a dream for lithographers. This is truly necessary to understand error sources of ACLV, especially when the optical lithography is pushed into 130 nm regimes and beyond. This dream has become a reality at Texas Instruments with the help of scatterometry. This paper describes the development and characterization of the scatterometer based scanner lens testing technique (ScatterLith) and its application in 193 nm and 248 nm scanner lens fingerprinting. The entire procedure includes a full field exposure through focus in a micro stepping mode, scatterometer measurement of focus matrix, image field analysis and mapping of lens curvature, astigmatism, spherical aberration, line-through pitch analysis and ACLV analysis (i.e. across chip line width variation). ACLV has been directly correlated with image field deviation, lens aberration and illumination source errors. Examples are given to illustrate its applications in accurate focus monitoring with enhanced capability of dynamic image field and lens signature mapping for the latest ArF and KrF scanners used in manufacturing environment for 130nm node and beyond. Analysis of CD variation across a full scanner field is done through a step-by-step image field correction procedure. ACLV contribution of each image field error can be quantified separately. The final across slit CD signature is further analyzed against possible errors from illumination uniformity, illumination pupil fill, and higher order projection lens aberrations. High accuracy and short cycle time make this new technique a very effective tool for in-line real time monitoring and scanner qualification. Its fingerprinting capability also provides lithography engineers a comprehensive understanding of scanner performance for CD control and tool matching. Its extendibility to 90nm and beyond is particularly attractive for future development and manufacturing requirements.

Scatterometry, an optical metrology based on the principle of diffraction, has received a considerable amount of attention in the literature in the past decade. By measuring and analyzing the light scattered, or diffracted, from a patterned periodic sample, the dimensions of the sample itself can be measured. Applications of the technique have included the characterization of photomasks, the monitoring of focus, dose and the post exposure bake process, and even the characterization of three-dimensional features such as contact hole and DRAM arrays. Like other optical metrologies, scatterometry measurements are rapid, non-destructive and highly repeatable. The most widely reported scatterometry data have been for measurements of developed photoresist and etched poly-Si gratings. Although these types of features represent a considerable portion of a typical process, other types of materials, such as metal layers, are also commonly present, and are important to characterize. In this work scatterometry measurement data from metal layers will be presented. The scatterometer used in this investigation was the well-known 2- (Theta) variety, where the scatter signature is obtained by measuring the diffraction efficiency of a particular order as the incident angle is varied. The analysis involved comparing the measured data to a library of theoretical scatter signatures (generated a priori from rigorous coupled wave theory) to find the best match. The measurements were performed at two process steps: pre-etch, where the patterned features were resist gratings on uniform metal layers, and post-etch/strip, where the patterned features were etched metal gratings. The composition of the metal stack starts with a silicon substrate, upon which is deposited 3000 A of oxide, followed by 500 A of Ti, 6000 A of AlCu and 250 A of TiN. A BARC layer and then the photoresist were deposited on this stack for patterning. The nominal patterned dimensions were 350 nm lines in 800 nm pitch gratings. Overall the sample set for this study included some 24 wafers with various AlCu layer thicknesses, providing a broad wafer split for analysis. Measurement results for linewidth and the various layer thicknesses will be presented, and comparisons to AFM measurements will be made. Results from assessing the repeatability of the 2-(Theta) scatterometer will also be presented, and indicate sub-nanometer precision (6-(sigma) ) for linewidth measurements. In addition, the practical aspects of the method, such as the modeling time required to generate the signature library as well as measurement speed and throughput will be presented.

In previous applications scatterometry has shown promise as a metrology for several process measurements. The linewidths of both resist and etched features, and the thicknesses of several underlying film layers, have been accurately characterized using the technique1 . Up until recently these results have been obtained by assuming the features being measured possessed a nominally square profile. However, as metrology tolerances shrink in proportion to device dimensions, errors in the measurement technique due to non-square line profiles could become significant. To test the ability of the scatterometry technique to measure non-square profiles, two models have been developed. The first profile model assumes the top and bottom corners of a resist line can be approximated as a segment of some circle with a given radius. With the center of the circle fixed in space by the overall height of the resist and a nominal linewidth, the sidewall of the line is then modeled as the tangent line that connects the two circles. This particular model can accommodate both overhanging (<900) and trapezoidal sidewalls (<900) with just four parameters: the radius of the top and bottom corners, and the nominal top and bottom linewidths. Comparisons between cross-section SEM images and scatterometry profiles using this model will be presented. The second model, which we call the "stovepipe' model, is a modified version of a simple trapezoid model and has applications to etched features. In this model an etched line is parameterized by assuming the trapezoidal portion of the sidewall starts at some distance below the top of the line, with the top portion of the line remaining square. In this manner an etched profile can be modeled with four parameters: the overall height of the etched line, the nominal etched linewidth, and the overall height and sidewall angle of the trapezoid layer. Once again, scatterometry profile results in comparison to cross-section SEM images will be presented. The use of both of these models has reduced the difference between scatterometry and SEM CD measurements. For example, the average difference of twelve resist CD measurements, when compared to crosssection SEM measurements, improves from 19.3 to 10.1 urn when the full profile model is incorporated.

Scatterometry, the characterization of periodic structures via diffracted light analysis, is shown to be a versatile metrology technique applicable to several processes involved in microlithography. Unlike contemporary inspection technologies, such as scanning force microscopy (SFM) and scanning electron microscopy (SEM), scatterometry is rapid, non- destructive, inexpensive and has the potential for use in-situ. Furthermore, the flexibility of the technique allows it to be used for a number of different process measurements. In the production of a sub-micron microelectronic device, a typical series of process steps could involve the deposition of a poly-Si layer on oxide, followed by the application of an anti- reflection coating (ARC) and resist layer. Thus in total there are four parameters which will ultimately affect the overall quality of subsequent processing: the linewidth of the resist, the resist height, and the thicknesses of the ARC and poly-Si. We have demonstrated that the scatterometer measurement technique is robust to changes in the thickness of underlying films. Indeed, there is sufficient information in one signature to determine four parameters at once, even when the linewidth dimensions are as small as 0.16 micrometer and the poly-Si thickness is on the order of 2500 angstrom. Results from determining these dimensions on several wafers show excellent agreement between the scatterometry measurements and measurements made with other metrology instruments (top down and cross-section SEM, and ellipsometer). For example, the average bias between nine scatterometry and cross-section SEM measurements on nominal 0.35 micrometer lines is minus 1.7 nm; for 0.25 micrometer lines, the average difference is minus 7.3 nm. In addition, results from measuring the sidewall angle (a fifth parameter) from these same scatter signatures indicate that the resist profiles at optimum focus and exposure are near-vertical. Finally, the dynamic repeatability of this technique is shown to be excellent for all of the parameters measured (linewidth, resist height, ARC thickness and poly thickness). For example, the 3(sigma) repeatability of measurements on a 207 nm linewidth is 0.75 nm and the 3 sigma repeatability for measurements on a 311 nm linewidth is 1.08 nm.
