Image sensor package and miniaturized endoscope having a scattering layer to provide uniform illumination

An endoscope, comprising

• a tube comprising a first opening and a second opening;
• an image sensor package, disposed at the first opening of the tube to capture images and generate a corresponding electronic signal, and comprising:
• a substrate comprising a plurality of first conductive contacts, a plurality of second conductive contacts, and a plurality of third conductive contacts, wherein the plurality of second conductive contacts and the plurality of third conductive contacts are electrically connected with the plurality of corresponding first conductive contacts;
• an image sensor, disposed on the substrate and electrically connected with the plurality of second conductive contacts;
• a plurality of light-emitting elements, disposed on the substrate, adjacent to the image sensor and electrically connected with the plurality of third conductive contacts;
• a scattering layer, covering at least one sidewall of the plurality of light-emitting elements and fill in the space between image sensor and light-emitting elements, an altitude of the scattering layer is lower than or equal to an altitude of a light-output surface of the plurality of light-emitting elements;
• and
• a first encapsulant, covering at the scattering layer and light-output surfaces of a plurality of light-emitting elements and encapsulating partial top sidewalls of the image sensor and the plurality of light-emitting elements, wherein an altitude of a top surface of the first encapsulant is equal to or lower than an altitude of a light-input surface of the image sensor;
• a plurality of cables, disposed inside the tube, wherein one end of the plurality of cables is electrically connected with the plurality of corresponding first conductive contacts of the substrate;
• and
• an electric connector, electrically connected with another end of the plurality of cables.
