PIN detector arrays and integrated readout circuitry on high-resistivity float-zone silicon

A new PIN-diode-based pixel detector, combining a VLSI readout circuit and a two-dimensional sequence of detecting elements on the same silicon medium, is developed. All signal charges are grouped into a designated low capacitance collection electrode to minimize spatial resolution and pixel pitch. A signal to single-channel-noise ratio is evaluated without signal charge loss from the collection electrode.
