Abstract:
(EN) The purpose of the present invention is to provide a color filter for an image sensor that can suppress reductions in transmittance for visible light and increase sensitivity in the visible light range, and is easily manufactured without on-chip limitations, an image sensor using this color filter for an image sensor, and a method for manufacturing this color filter for an image sensor. Provided is a color filter for an image sensor that has: an absorption type color filter having two or more types of absorption regions absorbing light of wavelengths that differ from each other; a reflective type wavelength cut filter having a reflective region for reflecting light of wavelengths from a wavelength λa to a wavelength λb and a transmittance region for transmitting light of wavelengths from the wavelength λa to the wavelength λb; and a bandpass filter for transmitting light of at least wavelengths from the wavelength λa to the wavelength λb.
(FR) L'invention a pour objet de fournir: un filtre coloré pour capteur d'image, qui peut éliminer des réductions de transmittance pour la lumière visible et augmenter la sensibilité dans la gamme de lumière visible, et se fabrique facilement sans limitations sur puce; un capteur d'image utilisant ce filtre coloré pour capteur d'image; et un procédé de fabrication du filtre coloré pour capteur d'image. L'invention concerne un filtre coloré pour capteur d'image, qui comprend: un filtre coloré de type à absorption présentant au moins deux types de zones d'absorption qui absorbent la lumière de longueurs d'onde différentes les unes des autres; un filtre de blocage de longueurs d'onde de type réfléchissant qui présente une zone réfléchissante pour réfléchir la lumière de longueurs d'onde d'une longueur d'onde λa à une longueur d'onde λb, et une zone de transmittance pour transmettre la lumière de longueurs d'onde de la longueur d'onde λa à la longueur d'onde λb; et un filtre passe-bande pour transmettre la lumière d'au moins des longueurs d'onde de la longueur d'onde λa à la longueur d'onde λb.
(JA) 可視光の透過率の低下を抑制して、可視領域の感度を高くでき、また、オンチップに限定されず製造が容易なイメージセンサー用カラーフィルター、このイメージセンサー用カラーフィルターを用いるイメージセンサー、および、このイメージセンサー用カラーフィルターの製造方法を提供する。互いに異なる波長域の光を吸収する2種以上の吸収領域を有する吸収型カラーフィルター、波長λaから波長λbの波長域の光を反射する反射領域と、波長λaから波長λbの波長域の光を透過する透過領域とを有する反射型波長カットフィルター、および、少なくとも波長λaから波長λbの波長域の光を透過するバンドパスフィルターを有する。
