    Abstract: To realize simplification of a process of forming hollow portions in a solid-state imaging apparatus, a plurality of light receiving portions is formed on a semiconductor substrate, and color filter layers as hollow portion forming layers are formed above the semiconductor substrate (FIG. 1A). A sealable layer for opening boundary portions of the color filter layers is formed on the color filter layers (FIG. 1B). Hollow portions are formed on side surfaces of the color filter layer by etching using the sealable layer as a mask (FIG. 1C). The sealable layer is heated and softened to connect mutually adjacent sealable layers to form a sealing layer for sealing the aperture regions of the hollow portions (FIG. 1D).
