Abstract
A photodetection element comprises a substrate having a first surface and a second surface opposite to each other, a first node region within the substrate and having a first conductivity type, a second node region within the substrate spaced apart from the first node region and having a second conductivity type different from the first conductivity type, and an avalanche multiplication region formed between the first node region and the second node region. The first node region, the avalanche multiplication region, and the second node region are arranged along a first direction parallel to the first surface.

A photodetection element comprising:
- a substrate having a first surface and a second surface opposite to each other;
- a first node region within the substrate and having a first conductivity type;
- a second node region within the substrate spaced apart from the first node region and having a second conductivity type different from the first conductivity type;
- and
- an avalanche multiplication region formed between the first node region and the second node region,
- wherein the first node region, the avalanche multiplication region, and the second node region are arranged along a first direction parallel to the first surface.
A photodetector comprising a photodetection element, a connection layer and an optical element layer that transmits incident light to the photodetection element,
- wherein the photodetection element includes, a substrate having a first surface and a second surface on opposite sides of each other, a first node region provided in the substrate and having a first conductivity type, a second node region spaced apart from the first node region in the substrate and having a second conductivity type different from the first conductivity type, and an avalanche multiplication region formed between the first node region and the second node region,
- wherein the first node region, the avalanche multiplication region, and the second node region are arranged along a first direction parallel to the first surface,
- wherein the connection layer includes conductive lines electrically connected to at least one of the first node region and the second node region.
An electronic device comprising a light emitting device and a photodetection element that detects incident light reflected from a subject and returned after being emitted from the light emitting device, and configured to measure a distance to the subject using time difference information between a transmission signal of the light emitting device and a detection signal of the photodetection element,
- wherein the photodetection element includes:
- a substrate having a first surface and a second surface provided on opposite sides of each other, a first node region provided within the substrate and having a first conductivity type, a second node region spaced apart from the first node region within the substrate and having a second conductivity type different from the first conductivity type, and an avalanche multiplication region formed between the first node region and the second node region,
- wherein the first node region, the avalanche multiplication region, and the second node region are arranged along a first direction parallel to the first surface.
