    摘要: The present disclosure provides methods and apparatus that enable characterization of an electrical property of a semiconductor specimen, e.g., dopant concentration of a near-surface region of the specimen. In exemplary method, a target depth for measurement is selected. This thickness may, for example, correspond to a nominal production thickness of a thin active device region of the specimen. A light is adjusted to an intensity selected to characterize a target region of the specimen having a thickness no greater than the target depth and a surface of the specimen is illuminated with the light. An AC voltage signal induced in the specimen by the light is measured and this AC voltage may be used to quantify an aspect of the electrical property, e.g., to determine dopant concentration, of the target region.

    摘要: A method and apparatus are described for the nondestructive readout of a latent electrostatic image formed on a sheet or layer of insulating material. A sheet or layer of semiconductor material is disposed in relatively close proximity to the insulating material. A latent electrostatic image formed on the insulating material (by any known means) causes a surface depletion layer to be produced by induction at the surface of the semiconductor material. The location and distribution of the accumulated charges on the semiconductor material are read out as analog electrical signals corresponding to the AC surface photovoltage induced on the semiconductor material as the semiconductor material is scanned with a low intensity modulated light beam of appropriate wavelength, the magnitude of the analog signals depending on the local charge density. The analog electrical signals so obtained are then digitized, processed and stored and/or displayed.

    摘要: A radiation detector includes a block of a material capable of interacting with ionizing radiation to produce charge carriers, an inductor positioned adjacent to the block and having an inductance that depends on a number of the charge carriers in the block, and a sensing circuit coupled to sense a change in the inductance and detect the ionizing radiation base on the change. The sensing circuit may particularly contain an RF synthesizer that drives the inductance, e.g., an LC circuit containing the inductance, and an analyzer that detects changes in the response of the inductance.

    摘要: An apparatus and method for the real-time, in-line testing of semiconductor wafers during the manufacturing process. In one embodiment the apparatus includes a probe assembly within a semiconductor wafer processing line. As each wafer passes adjacent the probe assembly, a source of modulated light, within the probe assembly, having a predetermined wavelength and frequency of modulation, impinges upon the wafer. A sensor in the probe assembly measures the surface photovoltage induced by the modulated light. A computer then uses the induced surface photovoltage to determine various electrical characteristics of the wafer.
