| Outline of Final Research Achievements |
We have developed pixel detectors including both sensor and circuit, using SOI (Silicon-on-insulator) technology which improves performance of CMOS circuit. The pixel circuit includes a preamplifier. To solve problems such as crosstalk between sensor and circuit, double SOI wafer has utilized. Top SOI layer was used as SOI-CMOS circuit and the bottom as a shield layer. The crosstalk at the preamplifier in the pixel circuit was suppressed by the middle SOI layer. The sensor has two storage capacitors in a pixel, and these can be alternately used. It helps to reduce readout dead time, and therefore the sensor can be used in various application research which requires continuous measurement.
