    • A method of fabricating an image sensor is provided. The method may include preparing a substrate with first to third pixel regions, coating a first color filter layer on the substrate, sequentially forming a first sacrificial layer and a first protection layer to cover the first color filter layer, forming a first photoresist pattern on the first protection layer to be overlapped with the first pixel region, performing a first dry etching process using the first photoresist pattern as an etch mask to the first sacrificial layer and the first protection layer to form a first color filter, a first sacrificial pattern, and a first protection pattern sequentially stacked on the first pixel region, and selectively removing the first sacrificial pattern to separate the first protection pattern from the first color filter.
    • 提供了一种制造图像传感器的方法。 该方法可以包括制备具有第一至第三像素区域的衬底,在衬底上涂覆第一滤色器层,顺序地形成第一牺牲层和第一保护层以覆盖第一滤色器层,在第一滤色器层上形成第一光致抗蚀剂图案 第一保护层与第一像素区域重叠,执行使用第一光致抗蚀剂图案作为第一牺牲层和第一保护层的蚀刻掩模的第一干蚀刻工艺以形成第一滤色器,第一牺牲图案和 第一保护图案,其顺序地堆叠在第一像素区域上,并且选择性地去除第一牺牲图案以将第一保护图案与第一滤色器分离。
