Abstract
Official abstract text for this publication.
A detection apparatus configured to detect soft X-ray radiation, includes a conversion unit and a circuit unit disposed on a semiconductor substrate. The conversion unit has a plurality of conversion elements that convert the soft X-ray radiation incident on the semiconductor substrate into electric charge. The circuit unit has an amplifier transistor that amplifies and outputs a signal supplied from the conversion unit. A shielding unit is disposed above the circuit unit. The shielding unit blocks the soft X-ray radiation incident on the circuit unit. Preferably, the soft X-ray shielding coefficient of a material that forms the shielding unit is higher than the soft X-ray shielding coefficient of each of aluminum and copper. Alternatively, a material that forms the shielding unit has an atomic number higher than or equal to 70.
