Park XE7
Product Description
Uncompromised High Performance
Park XE7 provides accurate measurement at highest nanoscale resolution than any other products in its class.It allows you to obtain sample images and its characteristic measurements true to its nano structure thanks to its flat, orthogonal, and linear scan measurements by its unique AFM architecture: independent XY and Z, flexure based scans. Furthermore, Park’s unique True Non-Contact™ mode provides you with the sharpest images, scan after scan without declining resolution.
For Current and Future Needs
Park XE7 empowers you to innovate now and in the future. It gives you ready access to the largest number of measurement modes in the industry. You can employ any of these modes now, and in the future to support your evolving needs. What’s more, the XE7 has the most open access design in the market that allows you to integrate and combine accessories and instruments to tailor it to your unique research requirements.
Easy to Use and High Productivity
Park XE7 together with its intuitive graphical user interface, and its automated tools, allows even novice users get from sample placement to scan results, fast. Starting from pre-aligned tip mount, easy sample and tip exchange, simple laser alignment, on-axis top-down optical viewing, to user friendly scan controls and software processing, the XE7 provides highest research productivity in AFM.
Economical Beyond the System Cost
Not only is Park XE7 the most affordable as a research grade AFM, it is also the most economical in total cost of ownership. Park’s True Non-Contact™ mode technology found in the XE7 allows users to save money on costly probe tips. Moreover, Park XE7 offers you much longer product life and upgradeability as a result of its compatibility with the most extensive types of modes and options available in the industry.

XE-Peformence
Figure 9. Zero background curvature by Park Systems XE-system (a) and typical background curvature of a conventional AFM system with a tube scanner (b). (c) shows the cross section of these background curvatures.
Figure 9. shows unprocessed AFM images of a bare silicon wafer taken with the XE-system (a), and with a conventional AFM (b). Since the silicon wafer is atomically flat, most of the curvatures in the image are scanner-induced artifacts. Figure 9. (c) shows the cross section of the images in Figure 9. (a) and (b). Since the tube scanner has intrinsic background curvatures, the maximum out-of-plane motion is as much as 80 nm when the X-axis moves 15 μm. The XE scan system has less than 1nm of out-of-plane motion for the same scan range. Another advantage of the XE scan system is its Z-servo response.
Figure 10. Figure 11.
Figure 10. is an image of a porous polymer sphere (Styrene Divinyl Benzene), whose diameter is about 5 µm, taken with the XE-system in Non-Contact mode. Since the Z-servo response of the XE-system is very accurate, the probe can precisely follow the steep curvature of the polymer sphere as well as small porous surface structures without crashing or sticking to the surface. Figure 11. shows another example that demonstrates the high performance of the z-servo response with a flat background.
Best Life, by True Non-Contact™ Mode
True Non-Contact™ Mode
- Less tip wear = Prolonged high-resolution scan
- Non-destructive tip-sample interaction = Minimized sample modification
- Immunity from parameter dependent results
Tapping Imaging
- Quick tip wear = Blurred low-resolution scan
- Destructive tip-sample interaction = Sample damage and modification
- Highly parameter-dependent
Longer Tip Life and Less Sample Damage
The sharp end of an AFM tip is so brittle that once it touches a sample, it becomes instantly blunt and limits the resolution of an AFM and reduces the quality of the image. For softer samples, the tip will damage the sample and also result in inaccuracies of sample height measurements. Consequently, preserving tip integrity enables consistent high resolution and accurate data. True Non-Contact Mode of theXE-AFM superbly preserves the tip, resulting in much longer tip life and less sample damageThe figure, displayed in 1:1 aspect ratio, shows the unprocessed raw data image of a shallow trench isolation sample imaged by the XE-AFM, whose depth is also confirmed by scanning electron microscope (SEM). The same tip used in the imaging of the sample shows no tip wear even after taking 20 images.
