  • Four-terminal methods for resistivity measurement of semiconducting materials
    Patent number: 7030633
    Abstract: This invention provides an innovative multi-line structure and an effective four-terminal method for the resistivity measurement of semiconductor materials. The multi-line structure and the four-terminal method not only allow one to perform resistivity measurement on any inorganic and organic semiconductor thin film conveniently, rapidly and accurately but also offer the means to study resistivity uniformity across the semiconductor thin film.
