Abstract: A method of manufacturing a solid-state imaging device includes: a first step of forming a recess portion on a top surface of a semiconductor substrate; a second step of selectively forming an impurity region of a first conductivity type in a lower portion of the recess portion by introducing impurities from a bottom surface of the recess portion; and a third step of forming a semiconductor layer in the recess portion, thus forming a photoelectric conversion portion which includes the impurity region and the semiconductor layer.

Abstract: A surface component film (2) is etched using a resist (3) as a mask, and the surface component film (2) is patterned according to the shape of an aperture (3a). This results in a step portion (4) having the same shape as the aperture (3a), with the sidewall (4a) of the step portion (4) exposed through the aperture (3a). The aperture (3a) is spin-coated with a shrink agent, reacted at a first temperature, and developed to shrink the aperture (3a). To control the shrinkage with high accuracy, in the first round of reaction, the aperture is shrunk by, for example, about half of the desired shrinkage. The aperture (3a) is further spin-coated with a shrink agent, reacted at a second temperature, and developed to shrink the aperture (3a). In this embodiment, the second-round shrink process will result in the desired aperture length. The second temperature is adjusted based on the shrinkage in the first round.
