    摘要: A method suitable for cleaning the interior surfaces of a process chamber is disclosed. The invention is particularly effective in removing silicon nitride and silicon dioxide residues from the interior surfaces of a chemical vapor deposition (CVD) chamber. The method includes reacting nitrous oxide (N2O) gas with nitrogen trifluoride (NF3) gas in a plasma to generate nitric oxide (NO) and fluoride (F) radicals. Due to the increased density of nitric oxide radicals generated from the nitrous oxide, the etch and removal rate of the residues on the interior surfaces of the chamber is enhanced. Consequently, the quantity of nitrogen trifluoride necessary to efficiently and expeditiously carry out the chamber cleaning process is reduced.

    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.
