    摘要: A method of inline inspection of photovoltaic material for electrical anomalies. A first electrical connection is formed to a first surface of the photovoltaic material, and a second electrical connection is formed to an opposing second surface of the photovoltaic material. A localized current is induced in the photovoltaic material and properties of the localized current in the photovoltaic material are sensed using the first and second electrical connections. The properties of the sensed localized current are analyzed to detect the electrical anomalies in the photovoltaic material.

    摘要: One embodiment disclosed relates to a method for robustly detecting a defective high aspect ratio (HAR) feature. A surface area of a semiconductor specimen with HAR features thereon is charged up, and a primary beam is impinged onto the surface area. Scattered electrons that are generated due to the impingement of the primary beam are extracted from the surface area. An energy filter is applied to remove the scattered electrons with lower energies, and the filtered electrons are detected. Image data is generated from the detected electrons, and an intensity threshold is applied to the image data.
