Abstract

See full text

A sensor device (100, 2800) for detecting particles, the sensor device (100, 2800) comprising a substrate (102), a first doped region (104) formed in the substrate (102) by a first dopant of a first type of conductivity, a second doped region (106, 150) formed in the substrate (102) by a second dopant of a second type of conductivity which differs from the first type of conductivity, a depletion region (108) at a junction between the first doped region (104) and the second doped region (106, 150), a sensor active region (110) adapted to influence a property of the depletion region (108) in the presence of the particles, and a detection unit (112) adapted to detect the particles based on an electric measurement performed upon application of a predetermined reference voltage between the first doped region (104) and the second doped region (106, 150), the electric measurement being indicative of the presence of the particles in the sensor active region (110).
