Features:

Micro Magnetics is dedicated to providing innovative and powerful solutions to our customers over a wide range of applications. Our mission is to deliver high-quality products and services through the committed efforts of our well-trained and motivated employees. Our logo symbolizes three aspects of this mission:

The series of dots are symbolic of our emphasis on teamwork and development of multiple technologies to provide solutions, not just products. The decreasing size of the dots represents our drive to pioneer new devices and technologies based on nanotechnology, which would allow improved performance with increasing miniaturization.

The hysteresis curve refers to our focus on magnetic phenomena and devices. The hysteresis curve is one of the most fundamental aspects of a magnetic device, and so this symbol represents the strong scientific background of our engineering team and its capability to apply our cutting-edge research efforts to bring new solutions to the market.

The motto "Sensible Solutions" affirms our commitment to providing comprehensive solutions to customers. These solutions are sensible both in the literal sense, as they are based on sensor technology, and by the more conventional definition, as we are committed to providing cost-effective answers to challenging technical requirements.

Circuit Scan 1000, General Description:

Operating circuits within a semiconductor generate external magnetic fields near the surface of the device. These magnetic fields, while weak in strength, contain information about the spatial variation of current density flowing within the circuit. Micro Magnetics has developed the CS1000 to make practical use of this information and provide engineers with valuable information about what is going on inside circuitry non-destructively.

The Circuit Scan 1000 is a scanning magnetic microscope capable of capturing external magnetic fields generated by an operating circuit, and then analyzing these fields to provide a map of the current density distribution, with a spatial resolution on the order of tens of nanometers. The system uses a proprietary, ultra-sensitive magnetic sensor technology with deep sub-micron spatial resolution, the technology for which was initially developed in the Nanoscale Physics and Devices group at Brown University.

The CS1000 maps currents at extremely small scales through any dielectric or nonferrous overlayers, and has superior linear response over the full signal range seen in integrated circuits. Our proprietary magnetic sensors have a wide frequency response (0-5 GHz), and are thermally stable, requiring no special environmental controls. Additionally, they have outstanding spatial resolution, resolving features to date as small as 60 nanometers, a feature size well below the current state-of-the-art in the semiconductor industry.

The system is designed to be straight-forward and easy to use. Some of the features which come standard on the CS1000 are full optical and/or NIR navigation and ROI selection, automatic field and current density map overlay, sample surface detection and mapping, automatic sample tilt and contour correction, five distinct contact and non-contact scanning modes, a small-footprint vertical sensing probe, intuitive image stitching, a “Repeat Scan” function to automatically vary parameters, and a full set of calibration functions.

The system also includes our powerful VIsta stand-alone analysis package, which features flexible data display and interpretation, a quantitative analysis package for extraction of all relevant current parameters (including current amplitude and conductor width and depth), two powerful current density conversion algorithms, compact data file formats, exporting of data and images to common file formats, an image comparison and subtraction suite, and automatic overlay of magnetic and current density maps.
