no. 1 approach

[0167] The first embodiment: the method in which the microlens body is directly covered with a light-transmitting cured film;

no. 2 approach

[0168] The second embodiment: a method in which the microlens body is coated with an outer coating layer and further coated with a light-transmitting cured film;

no. 3 approach

[0169] The third embodiment: a method of forming a light-transmitting cured film between the microlens body and the semiconductor light-receiving unit;

[0170] Among the above, the first embodiment is preferable. Hereinafter, the manufacturing method of the first embodiment will be described in detail.

[0171] (coating of composition)

[0172] It is preferable to use the resin composition for translucent cured film formation of this embodiment as a formation material of an antireflection film and a low-refractive-index film. The method of coating on a workpiece such as a lens body in order to form a cured film is not particularly limited, and an appropriate known coating method can be used. For example, a spin coating method, a dip coating method, a roll doctor method, a spray method, etc. can be used. It is preferable to remove the solvent contained in the coating film by subjecting the applied coating film to heat treatment or the like as necessary.

Abstract

The present invention provides an optical member group capable of realizing good photosensitivity, and a solid-state imaging element using the optical member group. The optical member group includes a first optical member obtained by curing a curable resin composition, and a second optical member covered with the first optical member, wherein the first optical member has a refractive index of 1.25 to 1.45, and the above The refractive index of the second optical member is 1.65 to 1.95.

Description

technical field [0001] The present invention relates to an optical member set and a solid-state imaging device using the optical member set. Background technique [0002] Recently, there are various types of optical devices, and most of them have a structure in which an anti-reflective low-refractive index film is formed on the surface of an optical mechanism. The optical mechanism is not limited to one with a flat surface, and examples include brightness-enhancing lenses or diffusion lenses for liquid crystal backlights, Fresnel lenses, lenticular lenses, and microlenses used in screens of video projection televisions. For such devices, by forming fine structures mainly using resin materials, desired geometrical optical properties can be obtained, and generally, in order to further impart anti-reflection properties, low refractive index can be formed in a form suitable for the surface of these fine structures. membrane. [0003] Among them, research and development on mat...
