摘要： A microlens structure includes lower lens layers on a substrate. A sputtered layer of glass, such as silicon oxide, is applied over the lower lens layers at an angle away from normal to form upper lens layers that increase the effective focal length of the microlens structure. The upper lens layers can be deposited in an aspherical shape with radii of curvature longer than the lower lens layers. As a result, small microlenses can be provided with longer focal lengths. The microlenses are arranged in arrays for use in imaging devices.

摘要： An improved imaging device having a pixel arrangement featuring a multilayer light shield. The multilayer light shield includes stacked layers of light-shielding and light-transparent material. The light-transparent material, such as a dielectric, is selected to have a stress, such as a tensile stress, that offsets the stress, such as a compressive stress, of the light shielding material. Without the stress offset, the high compressive stress of the refractory metal could damage the integrity of the nearby silicon. The refractory metal is capable of withstanding the high temperatures associated with front end CMOS processing. The laminate structure allows the light shield to be placed close to the pixel surface. The light-transparent material has a thickness equal to about one-quarter wavelength of the light to be blocked, to act as an anti-reflective coating. An aperture in the light shield exposes the active region of the pixel's photoconversion device.

摘要： A transient index stack having an intermediate transient index layer, for use in an imaging device or a display device, that reduces reflection between layers having different refractive indexes by making a gradual transition from one refractive index to another. Other embodiments include a pixel array in an imaging or display device, an imager system having improved optical characteristics for reception of light by photosensors and a display system having improved optical characteristics for transmission of light by photoemitters. Enhanced reception of light is achieved by reducing reflection between a photolayer, for example, a photosensor or photoemitter, and surrounding media by introducing an intermediate layer with a transient refractive index between the photolayer and surrounding media such that more photons reach the photolayer. The surrounding media can include a protective layer of optically transparent media.

摘要： A microlens has a surface with an effective index of refraction close to the index of air to reduce reflection caused by change in indices of refraction from microlens to air. The microlens having an index of refraction approximately the same as that of air is obtained by providing a rough or bumpy lens-air surface on the microlens. Features protrude from the surface of a microlens to create the rough surface and preferably have a length of greater or equal to a wavelength of light and a width of less than a sub-wavelength of light, from about 1/10 to ¼ of the wavelength of light. The features may be of any suitable shape, including but not limited to triangular, cylindrical, rectangular, trapezoidal, or spherical and may be formed by a variety of suitable processes, including but not limited to mask and etching, lithography, spray-on beads, sputtering, and growing.

摘要： Microlenses are fabricated with a refractive-index gradient. The refractive-index gradient is produced in a microlens material such that the refractive index is relatively higher in the material nearest the substrate, and becomes progressively lower as the layer gets thicker. After formation of the layer with the refractive-index gradient, material is etched from the layer through a resist to form microlenses. The index of refraction can be adjusted in the microlens material by controlling oxygen and nitrogen content of the microlens materials during deposition. High-oxide material has a lower index of refraction. High-oxide material also exhibits a faster etch-rate. The etching forms the material into a lens shape. After removal of the resist, the microlenses have a lower relative refractive index at their apex, where the index of refraction preferably approaches that of the ambient surroundings. Consequently, light loss by reflection at the ambient/microlens interface is reduced.
摘要翻译：用折射率梯度制造微透镜。在微透镜材料中产生折射率梯度，使得最靠近衬底的材料的折射率相对较高，随着层变厚而变得越来越低。在形成具有折射率梯度的层之后，通过抗蚀剂从层中蚀刻材料以形成微透镜。通过在沉积期间控制微透镜材料的氧和氮含量，可以在微透镜材料中调整折射率。高氧化物材料的折射率较低。高氧化物材料也具有更快的蚀刻速率。蚀刻将材料形成为透镜形状。去除抗蚀剂后，微透镜在其顶点处具有较低的相对折射率，其中折射率优选接近周围环境的折射率。因此，减少了在环境/微透镜界面处的反射的光损失。
