SYSTEM COMPONENTS This section briefly describes the major components of the Dektak 150 system. For a complete listing of components and optional accessories, see Appendix B, Technical Specifications and Purchased Options. System Configurations The Dektak 150 stylus profiler comes in the following three configurations: •...
The optional Dektak 150 monitor provides a 17-inch, high-resolution, flat-panel color display. It shows programs and graphics in full color, along with a color video image of the sample surface from the USB camera in the optical assembly. The Dektak 150 software displays the substrate either alone or with superimposed graphics.
50 mm, 100 mm and 150 mm wafer alignment pins, the stage chuck provides three-point suspension for performing stress analysis. Options and Accessories A number of options and accessories are available for the Dektak 150, including: • A 4-inch Y auto stage that enables 3D mapping (see Figure 1-2).
Options. HOW THE SYSTEM WORKS The Dektak 150 profiler takes measurements electromechanically by moving the sample beneath a diamond-tipped stylus. The high-precision stage moves a sample beneath the stylus according to a user-programmed scan length, speed and stylus force. The stylus is mechanically coupled to the core of an LVDT (Linear Variable Differential Transformer).
Window on page 1-8). NOTE – When the optional Cantilever Deflection software is installed, the Dektak 150 profiler moves the stylus in a manner that produces highly accurate force-over-time measurements. The scan drive does not move. Profile Manipulation and Measurement An initial scan profile may require software leveling, zero referencing and software magnification to zoom in on an area of interest.

Page 94
If not, repeat the manual leveling procedure above. NOTE – For maximum performance of the Dektak 150, it is important to position the sample surface to within +/- 0.01º of level. Use the formula tan-1 (slope of leveled trace) to determine the level accuracy.
NOTE – If the profile trace is extremely out of level, change the measurement range to the maximum range of 2,620kÅ. Level the trace as described above, change to the intermediate range and repeat the procedure until leveled. The best level is achieved by using the 65kÅ range.
SETTING THE ZERO POINT You may select any point on the profile trace as the zero point. The zero point is the point of reference from which all measurements are taken. Software leveling sets both the R and M cursor intercepts at zero. However, when the Zero function is activated, it sets the zero point only at the R cursor intercept.

NALYTICAL UNCTIONS The analytical functions that are included as part of the standard Dektak 150 software allow you to perform complex analytical computations on the profile data. ABOUT ANALYTICAL FUNCTIONS The Dektak 150 application has many different analytical functions for measuring surface texture and other parameters.
Figure 6-1: Analytical Functions Dialog Box from Data Plot Window If you plan to conduct extensive surface texture analysis, refer to the ANSI B46.1 specification on surface texture. You can obtain a copy of this specification from the American Society of Mechanical Engineers, 345 East 47th Street, New York, NY 10017, telephone number: 1-800-843-2763, web site: www.asme.org.

MaxRa (Maximum Roughness) Identifies the portion of the assessment length that has the highest Ra. The assessment length, Ra (Average Roughness) defined by the cursors, divides into nineteen overlapping segments. Each segment is equal to one-tenth of the assessment length distance. The Ra is calculated for each segment. The R Formerly known as Arithmetic Average (AA) and Center Line Average (CL), Ra is the universally recognized, and most used, international parameter of roughness.
Page 153
Rq (Root-Mean-Square (RMS)) Determines the root-mean-square value of roughness corresponding to Ra (see Figure 6-3). Rq has the greatest value in optical applications where it is directly related to the optical quality of a surface. Figure 6-3: Rq Roughness Analytical Function Rt (Maximum Peak to Valley) The sum total of the maximum peak and maximum valley measurements of roughness within the assessment length (Rt = Rp + Rv) (see...
Page 154
Figure 6-5: Rv Roughness Analytical Function RZ_din (Ten Point Height Average) The average height difference between the five highest peaks and the five lowest valleys in accordance with DIN 4768/1 specification published by the Deutsche Institut fuer Normung c.v. (see Figure 6-6).
WAVINESS PARAMETERS The following parameters are listed alphabetically. Wa (Arithmetic Average of Waviness) The average deviation of waviness from the mean line (see Figure 6-7). (Corresponds to Ra.) Figure 6-7: Wa Waviness Analytical Function WMaxdev (Maximum Deviation of Waviness) Measures the distance of the furthest data point above or below the mean line of the waviness profile.
HEIGHT PARAMETERS The following parameters are listed alphabetically. ASH (Delta Average Step Height) Used to obtain a step height measurement in applications where roughness or noise is present on the profile trace. It computes the difference between two average height measurements. Avg Ht (Average Height) Calculates the average height of a step with respect to the zero line, using the R and M cursors to define the area of measurement.
Perim (Perimeter) Calculates the outside perimeter of a profile between the R and M cursors. A horizontal reference line is created using the R and M cursor intercepts. You must level the profile for accurate results. Radius A least-squares-arc is fitted to the data points and the radius is calculated from the equation for a circle.

Figure 6-9: Analytical Results Display with Ra from Raw Data DETERMINING THE CUTOFF WAVELENGTH The Dektak 150 application is equipped with short pass and long pass digital filters for filtering out high and low frequency signals. The cutoff frequencies define the intended difference between roughness and waviness.
8 equals 4.10, so the minimum acceptable cut-off wavelength is 5 µm. The scan length must equal the cut-off wavelength, so the maximum cutoff length is 2000. Therefore, you must select a cut-off value between 5 and 2000 µm. As shown in Figure 6-10, you set the filter cutoff values in the Roughness and Waviness Filters dialog box, which provides the following three separate cut-off filters for selecting the wavelength...

Stress Measurement is an optional feature that must be installed in the Dektak software prior to use. The Dektak 150 stress measurement function calculates tensile or compressive stress on processed wafers. Its algorithm creates a curve comprising stress values for every data point on the scan trace. If...
Figure C-1: Dektak Stress Measurement Formula Figure C-2: Analytical Results Window NOTE – Only those values of the stress curve between the cursors are considered. THREE-POINT SUBSTRATE SUSPENSION To compensate for substrate deflection created by gravity or by a vacuum hold stage, the stress measurement provides three-point substrate suspension.
CREATING A STRESS REFERENCE Prior to calculating stress, you must establish a reference. You can calculate stress using a straight line as the reference, or by producing a preliminary reference scan on the sample prior to processing. In order to accurately measure stress, the reference scan and the scan produced after thin film deposition must have identical scan parameters, including cursor locations (stress computes the data between the reference and measurement cursors).
