5. The liquid module, atmosphere and temperature control module can also be extend option.


How it works:
The probe is composed of a needle tip attached to the front end of a crossbar. When the probe tip is in contact with the surface of the sample, the elasticity of the crossbar is equivalent to the force between the atoms. The force will move the bar in the direction of the vertical force. The source of force includes the Van der Waals force of the probe and the surface and the Coulomb repulsive force between the probe and the outer electrons of the surface..

Therefore, the fluctuation of the surface of the sample causes the horizontal bar to shift up and down. Piezoelectric scanner with three-axis displacement capability enables the sample to scan back and forth in the selected area and detect the offset of the bar. The feedback circuit of the system and the piezoelectric material scanner are on the height axis The upper distance fine-tuning function is combined to maintain the fixed atoms during the scanning process by adjusting the distance between the probe and the sample, so when AFM scans an area, the vertical fine-tuning distance is stored as a two-dimensional internal function to form the so-called scanning area. Atomic force images, which usually correspond to the image of the high and low fluctuations of the surface of the scanning area, also known as height images.

1. Evaluate the difference before and after wafer processing (SiO2, GaAs, SiGe, etc.)
2. Determine the treatment effect of biomedical equipment (eg plasma treatment), such as contact lenses, catheters and coated stents
3. Check the effect of surface roughness on adhesion
4. Evaluate the groove shape and cleanliness of the patterned wafer
Analysis items:
1. Coating analysis: roughness analysis, film thickness analysis, hole size analysis
2. Nano material analysis: particle size analysis, dispersion analysis
3. The surface structure can be converted into 3D images, which can quickly solve the material structure and morphology.
4. Material surface elasticity distribution, frictional force distribution, charge distribution, magnetic area distribution analysis, etc.
