    摘要： System and method for processing a semiconductor device surface to reduce dark current and white pixel anomalies. An embodiment comprises a method applied to a semiconductor or photodiode device surface adjacent to a photosensitive region, and opposite a side having circuit structures for the device. A doped layer may optionally be created at a depth of less than about 10 nanometers below the surface of the substrate and may be doped with a boron concentration between about 1E13 and 1E16. An oxide may be created on the substrate using a temperature sufficient to reduce the surface roughness below a predetermined roughness threshold, and optionally at a temperature between about 300° C. and 500° C. and a thickness between about 1 nanometer and about 10 nanometers. A dielectric may then be created on the oxide, the dielectric having a refractive index greater than a predetermined refractive threshold, optionally at least about 2.0.

    摘要： An image sensor includes a substrate having opposite first and second sides, a multilayer structure on the first side of the substrate, and a photo-sensitive element on the second side of the substrate. The photo-sensitive element is configured to receive light that is incident upon the first side and transmitted through the multilayer structure and the substrate. The multilayer structure includes first and second light transmitting layers. The first light transmitting layer is sandwiched between the substrate and the second light transmitting layer. The first light transmitting layer has a refractive index that is from 60% to 90% of a refractive index of the substrate. The second light transmitting layer has a refractive index that is lower than the refractive index of the first light transmitting layer and is from 40% to 70% of the refractive index of the substrate.
