    Abstract: The present disclosure relates to a semiconductor image sensor with improved quantum efficiency. The semiconductor image sensor can include a semiconductor layer having a first surface and a second surface opposite of the first surface. An interconnect structure is disposed on the first surface of the semiconductor layer, and radiation-sensing regions are formed in the semiconductor layer. The radiation-sensing regions are configured to sense radiation that enters the semiconductor layer from the second surface and groove structures are formed on the second surface of the semiconductor layer.

    Abstract: A semiconductor device includes a substrate, a device layer, an anti-reflective coating layer, reflective structures, a composite grid structure, a passivation layer and color filters. The device layer is disposed on the substrate, in which trenches are formed in the device layer and the substrate. The anti-reflective coating layer conformally covers the device layer, the substrate and the trenches. The reflective structures are disposed on the anti-reflective coating layer in the trenches respectively. The composite grid structure overlies the anti-reflective coating layer and the reflective structures. The composite grid structure includes cavities passing through the composite grid structure, and the composite grid structure includes a metal grid layer and a dielectric grid layer sequentially stacked on the reflective structures. The passivation layer conformally covers the composite grid structure. The color filters respectively fill the cavities.

    Abstract: The present disclosure describes heat dissipation structures formed in functional or non-functional areas of a three-dimensional chip structure. These heat dissipation structures are configured to route the heat generated within the three-dimensional chip structure to designated areas on or outside the three-dimensional chip structure. For example, the three-dimensional chip structure can include a plurality of chips vertically stacked on a substrate, a first passivation layer interposed between a first chip and a second chip of the plurality of chips, and a heat dissipation layer embedded in the first passivation layer and configured to allow conductive structures to pass through.

    Abstract: The present disclosure is directed to a method for forming a light blocking material layer on a back side illuminated image sensor device. The light blocking material layer can block or absorb light rays incoming to the back side illuminated image sensor device at grazing incident angles. The light blocking material layer can be formed using a self-aligned process that does not require the use of a photolithography mask or photolithography operations. For example, the light blocking material layer can be formed over an image sensor device and subsequently etched so that the light blocking material layer remains in areas where light rays incoming at grazing incident angles enter the back side illuminated image sensor device.
