Abstract
Integrated bolometers of a volume of about 0.05 mm(3) are fabricated b y the technique of silicon micromachining. As thermistor serves a heav ily phosphorus doped area implanted in the absorber surface. The optim um thermistor doping was determined with respect to a high resistance gradient, but at the same time with resistance values low enough for p roviding signals which are reasonably high. Measurements of low-energe tic gamma-rays and conversion electrons indicated the high sensitivity of our detectors, however unfortunately for picking up noise, too. Th e steps to improve the current energy resolution are reported.
