  • Publication number: 20240105744
    Abstract: An image sensor includes a photoelectric conversion layer, a plurality of deep trench isolations, a first color filter, a first deflector, and a covering layer. The photoelectric conversion layer includes a first photodiode and a second photodiode. The deep trench isolations separate the first photodiode and the second photodiode, in which a pixel dimension is determined by a distance between two adjacent deep trench isolations. The first color filter is disposed on the first photodiode and the second photodiode. The first deflector is disposed on the first color filter. The covering layer covers and surrounds the first deflector. A refractive index of the covering layer is greater than a refractive index of the first deflector, and a difference value between the refractive index of the covering layer and the refractive index of the first deflector is in a range from 0.15 to 0.6.

  • Patent number: 10497847
    Abstract: A heat dissipation substrate structure includes a multilayer circuit board including a core board and build-up boards, a heat conduction layer, a cavity structure, bonding pads, and vias. The heat conduction layer is disposed within the core board, or on a surface of the core board, or on a surface of one of the build-up boards. The cavity structure is in the multilayer circuit board with respect to the heat conduction layer and exposes a first surface of the heat conduction layer. The bonding pads are on the surface of the multilayer circuit board at a side of a second surface of the heat conduction layer. The portions of the vias are connected to portions of the bonding pads and the heat conduction layer. Accordingly, heat flow can be distributed via a heat dissipation path from the bonding pads through the vias to the heat conduction layer.
