Patent ID: 8772070

Claim:
A method for manufacturing solid-state imaging device, the method comprising: a step of forming a plurality of frame-shaped spacers and a ring-shaped spacer surrounding the frame-shaped spacers along an outer periphery of a transparent substrate, on one surface of the transparent substrate that serves as a base material of a cover glass; a step of providing a mask material on a side of the one surface of the transparent substrate to cover the frame-shaped spacers and the ring-shaped spacer; a step of removing the transparent substrate from a side of the other surface to set thickness within a predetermined range; a step of removing the mask material from the transparent substrate; a step of laminating a first support wafer on the other surface of the transparent substrate, the other surface of the transparent substrate being an opposite surface to the one surface on which the spacers are formed; a step of forming a plurality of solid-state imaging elements on one surface of a semiconductor substrate; a step of removing the semiconductor substrate from a side of the other surface to set thickness within a predetermined range; a step of laminating a second support wafer on the other surface of the semiconductor substrate, the other surface being of the semiconductor substrate being an opposite surface to the one surface on which the plurality of solid-state imaging elements are formed; a step of bonding the semiconductor substrate and the transparent substrate through the spacers; a step of releasing the first support wafer and the second support wafer from the transparent substrate and the semiconductor substrate; a step of dicing the transparent substrate; and a step of dicing the semiconductor substrate.
