Title:
飛行時間型撮像素子
Document Type and Number:
Japanese Patent JP6930805
Kind Code:
B2
Abstract:
The invention relates to a majority current assisted detector device, comprising a semiconductor layer (40) of a first conductivity type, at least two control regions (MIX0, MIX1) of the first conductivity type, at least two detection regions (DET0, DET1) of a second conductivity type opposite to the first conductivity type and means for generating a majority carrier current associated with an electrical field. The detection regions surround the control regions for forming at least two taps. The concentration of dopants of the first conductivity type in the semiconductor layer (40) provides an electrical insulation between the detection regions by avoiding leakage of minority carriers from the detection regions (DET0, DET1). When the detector device is configured for backside illumination, it may further comprise a well (45) of the first conductivity type between the two detection regions (DET0, DET1) for insulating the detection regions and wherein the well (45) comprises receiving pixel circuitry elements.
