STM Phaino : Nanoscope for industrial R&D

Move, zoom and see, all on a nanoscale

 

Nano Positioning and Auto Tip Approach

It's a breeze to locate the microstructures in question using the microscale camera and nanoscale XY motor stage. The 15-nm tip apex provides unsurpassable probing precision.
While the tip-to-sample approach is fully automated, the users can aslo manually perform fast Z movement or single step movement for optimal tip-to-sample distance.

Features & Specifications

  • Scanning tunnelling microscopy (STM) shows the three-dimensional morphology of sample surfaces at the atomic level. Nanovie STM Phaino is powered by dual scanners, one for high resolution while the other for large scan range. The scanners can be switched from one another depending on the size of the structures or for the sake of positioning, and it takes only one single push.

    High resolution scanner:
    • XY Range ≈ 0.8 μm
    • Z Range ≈ 0.8 μm
    • XY ≈ 1.6 μm (Extended Mode)
    Large range scanner:
    • XY Range ≈ 3.0 μm
    • Z Range ≈ 2.0 μm
    • XY ≈ 5.0 μm (Extended Mode)
     
    Optimal Physical Resolution:
    • XY Resolution ≈ 0.2 nm
    • Z Resolution ≈ 0.03 nm
    Standard Features:
    • Scan Mode: Constant Current
    • Spectroscopy Mode: Current Voltage (I-V)
    • Tip-to-sample Approach: Automatic
    • Image Size: 50 X 50 ~ 550 X 550 pts

    The above parameters may vary depending on calibration.

  • Nanovie STM Phaino provides a nanoscale positioning stage, allowing sample movement between scans. There is no more need to fully retract and re-approach the tip evey time repositioning is required. The high magnification CCD camera, confocal to the probe tip, allows the users to examine and easily search for the region of interest at a micrometer scale before digging into nanoscale scanning.

    XY Motor Stage:
    • XY Travel : 2.0 mm
    • XY Step < 100 nm
    • Software Control
    CCD Camera:
    • Magnification : 800X (or better)
    • Resolution : 2 MP (or better)
    • Used for "Approaching" & "Positioning" Phase.
     
    High Resolution Scanner with Motor Stage:
    • XY Range ≈ 1.6 μm
    • Z Range ≈ 0.8 μm
    Large Range Scanner with Motor Stage:
    • XY Range ≈ 5.0 μm
    • Z Range ≈ 2.0 μm
  • As semiconductor fabrication reached the 10-nm node and beyond, it became more and more crucial to be able to probe and identify the electronic properties of materials at a nanoscopic level, such as the local density of electronic states (LDOS) and the band gap. While STM offers the most precise probing and the highest electronic spectroscopy sensitivity compared to other probing systems, Nanovie STM further made it simple and efficient to find the nanostructures in question.
