Park XE15

Increase your productivity with our powerfully versatile atomic force microscope

The Park XE15 includes many unique capabilities that make it ideal for shared labs that handle a diverse range of samples, researchers doing multi variant experiments, and failure analysis engineers working on wafers. Its reasonable price and robust feature set also make it one of the best value large-sample AFMs in the industry.

Product Description

Unique MultiSample™ scan boosts research productivity

Maximize your efficiency with the only AFM that offers the ability to image and measure multiple samples in one pass. Simply load the stage with your samples and initiate the scan process. This feature also allows you to scan the samples under identical environmental conditions, improving the accuracy and reliability of your data.

Large sample size increases possibilities

Unlike most AFMs, the Park XE15 can scan a sample of up to 150 mm x 150 mm. This makes it ideal for researchers wanting to scan larger samples or failure analysis engineers who need to place silicon wafers on the stage.

Features adaptable to any need

The Park XE15 features our most inclusive set of scan modes and can process a range of sample sizes. This makes it uniquely suited to shared labs with a wide range of individual requirements.

The most convenient sample measurements with MultiSample™ scan

Park XE15 MultiSample™ scan system

  • Automated imaging of multiple samples in one pass
  • Specially designed multi-sample chuck for the loading of up to 16 individual samples
  • Fully motorized XY sample stage travels up to 150 mm x 150 mm

Using the motorized sample stage, MultiSample Scan™ enables programmable multiple region imaging in step-and-scan automation.

Here’s how it works:
1. Register multiple scan positions defined by a user
2. Image from the first scan position
3. Lift a cantilever
4. Move the motorized stage to the next user defined coordinate
5. Approach
6. Repeat scan

The registration of multiple scan positions are easily carried out by either entering sample-stage coordinates or sample de-skewing by two reference points. This automated feature greatly increases productivity by reducing the need for your interaction during the scan process.

Accurate XY Scan by Crosstalk Elimination

Park Systems’ advanced Crosstalk Elimination (XE) scan system effectively addresses all of the above-mentioned problems. In this configuration, we used a 2-dimentional flexure stage to scan the sample in only the XY direction, and a stacked piezoelectric actuator to scan the probe cantilever in the Z direction only. The flexure stage used for the XY scanner is made of solid aluminum. It demonstrates high orthogonality and an excellent out-of-plane motion profile. The flexure stage can scan large samples (~1 kg) up to a few 100 Hz in the XY direction. This scan speed is sufficient because the bandwidth requirement for the XY axes is much lower than that for the Z axis. The stacked piezoelectric actuator for the Z-scanner has a high resonance frequency (~10 kHz) with a high pushpull force when appropriately pre-loaded.

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. 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.

Better tip life, sample preservation, and accuracy with True Non-Contact™ Mode

In True Non-Contact™ Mode, the tip-sample distance is successfully maintained at a few nanometers in the net attractive regime of inter-atomic force. The small amplitude of tip oscillation minimizes the tip-sample interaction, resulting in superb tip preservation and negligible sample modification.

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. xe-afm
