Active Electrostatic Force Microscopy

2015 IEEE 22nd International Symposium on the Physical and Failure Analysis of Integrated Circuits, 2015
We present Active Electrostatic Force Microscopy, as a new integrated circuit analysis technique for tracing nets and localizing opens. We demonstrate non-destructive surface and subsurface potential mapping, similar to Electron Beam Absorbed Current microscopy, without the associated high energy electron beam damage to the dielectrics.

Electrostatic forces in atomic force microscopy

Physical Review B, 2002
In this paper we quantitatively compare various electrostatic models, which describe the interaction of a polarized atomic force microscopy tip with a molecularly smooth and grounded substrate, with a large experimental data set collected at many different tip potentials. The model by Hudlet et al. [Eur. Phys. J.

Electrostatic force gradient signal: resolution enhancement in electrostatic force microscopy and improved Kelvin probe microscopy

Nanotechnology, 2003
In the present work the electrostatic interaction of a real scanning force microscopy (SFM) probe with a sample is studied theoretically as well as experimentally. To model the probe, a complex system composed of a macroscopic cantilever, a mesoscopic tip cone and a nanometric tip apex is proposed.

Quantitative electrostatic force microscopy-phase measurements

Nanotechnology, 2004
The phase mode of electrostatic force microscopy (EFM-phase) is a scanning probe microscopy (SPM) technique used to measure electrostatic force gradient. EFM-phase has a higher resolution than scanning Kelvin probe microscopy (SKPM or SKM), but unlike SKPM it does not yield a direct measurement of local potential. Analytical calculations of tip–surface

Electrostatic and contact forces in force microscopy

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1991
We have been measuring the electrostatic and contact forces between a tip and a graphite surface in a force microscope, which uses a polarizing optical interferometer. For large distances where the electrostatic force predominates, the data are analyzed in terms of a model which introduces the elongated shape of an actual tip.

Reconstruction of electrostatic force microscopy images

Review of Scientific Instruments, 2005
An efficient algorithm to restore the actual surface potential image from Kelvin probe force microscopy measurements of semiconductors is presented. The three-dimensional potential of the tip-sample system is calculated using an integral equation-based boundary element method combined with modeling the semiconductor by an equivalent dipole-layer and ...
