ない場合がある。Color separation filters are used in solid-state color cameras, single-tube color cameras, etc., but in the case of special C: filters for solid-state color cameras, as shown in Figure 1, color solid-state image sensors are packaged solid-state image sensors (1 ) After accurately aligning the color separation filter (2) with the adhesive (3)
It is manufactured by bonding. In the figure, (5) shows a bonding pad part, (6) shows a wire, and (7) shows a lead frame. In this case, in the color separation filter ζ2l,), the dimensions of the color separation filter substrate and the dimension from the end of the color separation filter substrate to the colored image area are required to be highly accurate. In other words, if the cutting precision is poor, a portion of the color separation filter may come into contact with the pumping pin of the solid-state image sensor, and accurate C2 positioning and bonding may not be possible.

離フィルターの作製法である。That is, the gist of the present invention is to form colored image areas of a large number of color separation filters on a transparent support, and then cut the transparent support into the size of a single color separation filter substrate to form a large number of color separation filters. Regarding the method of manufacturing a color separation filter to obtain a color separation filter, a cutting accuracy confirmation mark is placed near the cutting line of the transparent support while forming a colored image area, and then the transparent support is cut into the size of a single color separation filter substrate. After that, the position of the cutting line relative to the cutting accuracy confirmation mark is observed to determine whether or not the cutting accuracy is appropriate.
以下、本発明につき図面を用いて詳細(二説明する。Hereinafter, the present invention will be explained in detail using the drawings.

色分離フィルターの着色画像部を形成する。The colored image areas of a large number of color separation filters are patterned on a transparent support such as glass using a photosensitive resin such as polyvinyl alcohol, gelatin, casein, or griux, to which dichromate is added as a photosensitizer. rear,
It is colored with an acid dye or the like to form a colored image of the first color. By repeating the same process for the second and third colors, a colored image portion of the color separation filter is formed.

の後、着色画像部を形成する。In addition, if necessary, a protective layer of transparent resin is formed for the purpose of protection, and a mark for confirming cutting accuracy is formed by turning (for example, metal chrome, etc.) near the cutting line of the transparent support. The image area of the color separation filter requires a light-shielding layer made of metal chromium, etc., so it is formed at the same time as the cutting accuracy check mark.The chromium layer is processed by sputtering on a transparent support to a thickness of about 1000A. After the film is formed, the resist is etched into a pattern after plate making.Then, a colored image area is formed.
