Abstract In this study we have investigated the magnetic field associated with a current flowing in a circuit using Magnetic Force Microscopy (MFM). The technique is able to identify the magnetic field associated with a current flow and has potential for failure analysis.

Abstract Subsurface wiring level anomalies in VLSI semiconductor devices are extremely difficult, if not impossible to analyze without de-processing the device to expose suspect wiring. Magnetic Force Microscopy (MFM) is a scanning probe technique that requires minimal sample preparation and has the capability to sense magnetic fields in proximity to thin film conductors with high lateral resolution [1]. In this study, multiple VLSI device conductors were intentionally modified and then the magnetic field around the energized conductors was analyzed using MFM. An overview of the technique and results of the magnetic field analysis are discussed.

Recently carbon nanotubes (CNTs) are reported to be able to generate large magnetic field because of their nanometer-size-diameter[2]. The magnetic fields around CNTs current path are investigated by magnetic force microscopy (MFM). Under the consideration of the magnetic properties of magnetically coated tip of MFM, tip heights, current directions, and background magnetic field, etc., the magnetic field distribution are analyzed. The distribution of the magnetic field generated by the CNTs current is found to be asymmetric, and its distribution anomaly is found to be a kind of hysteresis effect of the MFM cantilever materials.

Magnetic force microscopy (MFM) is used to investigate the surface magnetic structure of steels Fe–28Mn–8.5Al–1C–1.4Si under the different regimes of isothermal aging. A theoretical model for the MFM imaging of such structures is developed. Calculation of van der Waals forces is performed in order to interpret the topography images. The lateral resolution in terms of the magnetic field dependence on the surface coordinates is investigated. Finally, conditions that should be fulfilled for a good imaging of the samples are formulated.
