Abstract:
1. An integrated circuit comprising: a sensor disposed adjacent a first side of a semiconductor substrate of a first type, the sensor comprising a sensor semiconductor region of a second type within the semiconductor substrate, and the sensor semiconductor region forming a PN junction with the semiconductor substrate; a second element disposed at or adjacent to a second side of the semiconductor substrate, the second element comprising at least one of a device or a contact, and the second side of the semiconductor substrate being opposite the first side of the semiconductor substrate; and an insulated conductor within the semiconductor substrate, the insulated conductor comprising a first region of doped semiconductor extending between and contacting the sensor and the second element, the first region of doped semiconductor being of the second type, and the first region of doped semiconductor material having a lower doping concentration than the sensor semiconductor region.
