  • Publication number: 20240088182
    Abstract: In some embodiments, an image sensor is provided. The image sensor includes a photodetector disposed in a semiconductor substrate. A wave guide filter having a substantially planar upper surface is disposed over the photodetector. The wave guide filter includes a light filter disposed in a light filter grid structure. The light filter includes a first material that is translucent and has a first refractive index. The light filter grid structure includes a second material that is translucent and has a second refractive index less than the first refractive index.

  • Patent number: 7727975
    Abstract: This invention relates to a pectin-modified resistant starch prepared by cross-linking starch with pectin by pectinesterase reaction. Such resistant starch is low amylase digestible and thus is useful in food products, including nutritional supplements, to reduce calorie content and increase fiber content. This invention also relates to a composition containing the resistant starch and a process for the preparation of the same.
