Definitions
- the present invention relates to a thermosetting resin composition, a method for forming an antihalation film of a solid-state imaging device, an antihalation film for a solid-state imaging device, and a solid-state imaging device.
- the solid-state imaging device includes a MOS (Mea- ter-i-de-Sic- on-Dictor) type, a CCD (Charge Coupled Dev ice) type, etc., and one-dimensional solid-state imaging device and two-dimensional solid-state is there.
- MOS Metal- ter-i-de-Sic- on-Dictor
- CCD Charge Coupled Dev ice
- one-dimensional solid-state imaging device and two-dimensional solid-state is there examples of the former include, for example, a facsimile, and examples of the latter include, for example, a video camera.
- Such solid-state imaging devices are becoming more digital in recent years, and high-quality images are being sought with the users' high-quality orientation.
- An example is the increase in the number of pixels in digital cameras.
- Solid-state imaging devices are available for black and white and for color. Among them, solid-state imaging devices for color are manufactured by forming a color filter of three colors on a substrate on which the solid-state imaging device is formed. Although solid-state imaging devices are used as they are, convex lenses (microlenses) are further provided on the surface corresponding to each solid-state imaging device to enhance the sensitivity (focusing ability). See Hei 3- 223702)).
- a fine pattern is formed by using a lithography technique using a photosensitive material.
- a transparent resin is applied on a substrate on which a solid-state imaging device is formed, and a force filter is further formed, if necessary, and then the surface is planarized.

- the photosensitive material When patterning the photosensitive material in the process of forming the force filter and the micro lens, the photosensitive material is exposed to diffuse reflection light from the underlying substrate to expose the portion that you do not want to expose, and the actual pattern size is the target size In other words, there was a problem that “halation” occurred.

- the antihalation film formed prior to the color filter is exposed to a high temperature more than ever. It is known that conventionally known materials for antihalation films do not function as antihalation films when exposed to such high temperatures. This phenomenon is due to the fact that the radiation absorbing agent contained in the antihalation film material sublimes and dissipates in a high temperature range exceeding 150 ° C., resulting in a significant decrease in radiation absorbing ability. Presumed.
