一种图像传感器感光结构及其制作方法
摘要：
本发明公开了一种图像传感器感光结构及其制作方法，其特征在于，所述感光结构包括镀膜单元、微型透镜以及感光元件，所述感光元件位于所述微型透镜的正下方，用于接收透过微型透镜的入射光，所述微型透镜的上方覆盖镀膜单元，所述镀膜单元包括至少一种镀膜层；其中，入射光依次经过镀膜单元和微型透镜进入所述感光元件中。本发明提供的一种图像传感器感光结构在微型透镜上沉积镀膜单元，可以增加微型透镜的透射率，增加图像传感器的灵敏度；可以减少微型透镜表面的散射，消除光的散射对相邻像素的影响；可以不借助彩色滤光片和镜头镀膜，利用微型透镜表面镀膜来限制特定入射光波长，增加微型透镜的功能性。
摘要（英）：

The invention discloses an image sensor photosensitive structure and a manufacturing method thereof. The image sensor photosensitive structure is characterized in that it comprises a film coating unit, a micro lens and a photosensitive element; the photosensitive element is located right under the micro lens and is used for receiving incident light passing through the micro lens; the top of the micro lens is covered with the film coating unit; and the film coating unit comprises at least one film coating layer; wherein the incident light enters the photosensitive element successively through the film coating unit and the micro lens. According to the image sensor photosensitive structure, the film coating unit id deposited on the micro lens so as to increase the transmittance of the micro lens, increase the sensitivity of an image sensor, reduce the scattering of the surface of the micro lens, and eliminate the influence of light scattering on adjacent pixels. Without a color filter and a lens coating, a specific incident light wavelength is defined by the surface coating of the micro lens so that the functionality of the micro lens is enhanced.
