摘要： An image sensor has an array of image sensor pixels. Each image sensor pixel may have a gradient index lens formed in a passivation layer. The gradient index lens may be a converging or diverging gradient index lens. The gradient index lens may have a gradient index profile that is smooth or a gradient index profile having distinct regions of lower or higher refractive index. Regions of lower refractive index may be formed from ion implantation in the passivation layer. Each pixel may also have a polymer microlens, a color filter, a dielectric stack, and a photosensitive element in a substrate.

摘要： An electronic device may have an image sensor array that captures images. The image sensor array may include antireflective layers that increase the efficiency of the image sensor in gathering incoming light. The image sensor array may include a first antireflective layer between a color filter layer and a passivation layer and a second antireflective layer between the passivation layer and a dielectric stack. The first antireflective layer may have an index of refraction that is between the indexes of refraction of the color filter layer and the passivation layer and the second antireflective layer may have an index of refraction that is between the indexes of refraction of the dielectric stack and the passivation layer, thereby reducing the proportion of incident light that reflects off the interface between the color filter layer and the passivation layer and the interface between the passivation layer and the dielectric stack.

摘要： Methods and devices that incorporate microlens arrays are disclosed. An image sensor includes a pixel layer and a dielectric layer. The pixel layer has a photodetector portion configured to convert light absorbed by the pixel layer into an electrical signal. The dielectric layer is formed on a surface of the pixel layer. The dielectric layer has a refractive index that varies along a length of the dielectric layer. A method for fabricating an image sensor includes forming an array of microlenses on a surface of the dielectric layer, emitting ions through the array of microlenses to implant the ions in the dielectric layer, and removing the array of microlenses from the surface of the dielectric layer.
