An embodiment semiconductor device includes a substrate such as a silicon or silicon-containing film, a pixel array supported by the substrate, and a metal stress release feature arranged around a periphery of the pixel array. The metal stress release feature may be formed from metal strips or discrete metal elements. The metal stress release feature may be arranged in a stress release pattern that uses a single line or a plurality of lines. The metal stress release pattern may also use metal corner elements at ends of the lines.

The disclosure provides an image sensor device and a manufacturing method. The image sensor device includes a semiconductor substrate and a light sensing region in the semiconductor substrate. The image sensor device also includes a light blocking structure in the semiconductor substrate and adjacent to the light sensing region. A sidewall of the light blocking structure is a curved surface.

Image sensor device with light blocking structure

The present disclosure provides an integrated circuit device comprising a substrate having a back surface and a sensing region disposed in the substrate and being operable to sense radiation projected towards the back surface of the substrate. The device further includes a waveguide disposed over the back surface of the substrate. The waveguide is aligned with the sensing region such that the waveguide is operable to transmit the radiation towards the aligned sensing region. The waveguide includes a waveguide wall, and an inner region disposed adjacent to the waveguide wall. A diffractive index of the waveguide wall is less than a diffractive index of the inner region.
