Abstract
An imaging element for analysis of a sample includes an electrode adapted to receive the sample, a light-emitting element, disposed opposite the electrode, and separated from the electrode by an insulating protective layer, a voltage-controlled current source configured to supply current to the light-emitting element and comprising a control electrode electrically connected to the electrode, so that said light-emitting element generates a light wave in response to a voltage coming from the sample.
Claims18
An imaging element for analysis of a sample and comprising:
- an electrode adapted to receive the sample,
- a light-emitting element, disposed opposite the electrode, and separated from the electrode by an insulating protective layer,
- a voltage-controlled current source configured to supply current to the light-emitting element and comprising a control electrode electrically connected to the electrode, so that said light-emitting element generates a light wave in response to a voltage coming from the sample.
A method for manufacturing an imaging element for analysis of a sample, comprising:
- providing an electronic circuit comprising a bonding pad and a voltage-controlled current source, the current source comprising a control electrode electrically connected to the bonding pad,
- forming, on the electronic circuit, a light-emitting element,
- forming a transparent or semi-transparent insulating protective layer covering the light-emitting element and the bonding pad,
- forming, on the protective layer and opposite the light-emitting element, a transparent or semi-transparent electrode adapted to receive the sample, and
- forming, through the protective layer, a conductive via extending from the transparent or semi-transparent electrode to the bonding pad.
