[Field of Application of the Invention] The present invention relates to a solid-state image sensor. The present invention is particularly useful for a color solid-state image sensor in which a color separation filter is mounted directly on a photodetector. [Background of the Invention] Conventionally, a common manufacturing method is to manufacture a solid-state image sensor and a color separation filter separately, and then bond them together using an optical adhesive or the like while aligning the two.
Also, instead of optical adhesive, optical matching
Examples of using oil have also been reported. Further, a method for manufacturing a polychromatic optical filter is disclosed in Japanese Patent Application Laid-Open No. 53-99822, and a method for manufacturing a color separation filter is disclosed in Japanese Patent Application Laid-open No. 147823-1989. There is no mention of providing it directly. Further, although a color imaging device and a method for manufacturing the same are disclosed in Japanese Patent Application Laid-Open No. 53-47282, there is no mention of radiation-sensitive materials at all. Regarding the composition to be copied, Japanese Patent Application Laid-Open No. 50-83425
Although the publication discloses radiation-sensitive materials in the publication, these are merely techniques related to containers and plywood. [Object of the Invention] A first object of the present invention is to mount a color separation filter directly on the light detection section of a solid-state image sensor, thereby improving the workability of manufacturing the device. A second object of the present invention is to make the color separation filter in this case sufficiently accurate and of high quality. [Summary of the Invention] The first key point of the present invention is to use a radiation-sensitive organic polymer material for the so-called intermediate layer and protective layer constituting the color separation filter, which is advantageous for the subsequent manufacturing process of the solid-state image sensor. be. Second, it is more preferable that the organic polymer material described above has thermal crosslinkability. This is useful for strengthening intermediate layers used in the laminated structure of color separation filters. Thirdly, it is extremely advantageous for the radiation-sensitive organic polymer material to be of a so-called positive type in terms of process simplification. Even if it has negative radiation sensitivity, this property can be used for processing the filter part. However, as each intermediate layer is formed, it becomes necessary to perform crosslinking by exposing to a predetermined radiation, which increases the number of steps. Of course, even if a positive radiation-sensitive organic polymer material is used, each of the intermediate layers described above may be formed and exposed to a predetermined radiation, and then developed and subjected to the desired processing. Of course, it is okay to do so. When each layer is processed, the number of steps is the same as in the case of negative molding. However, even in this case, the positive type has the following advantages. That is, in the case of a positive type, a portion of the organic polymer material layer to be removed is exposed to radiation, whereas in the case of a negative type, a portion of the organic polymer material to be left is exposed to radiation. Naturally, the color separation filter base material is the part where the layer of the organic polymer material remains. Therefore, in the case of a negative type, the color separation filter base material is also irradiated with exposure radiation several times, which affects the deterioration of the filter characteristics. Positive types have no such sub-effects at all. Furthermore, in many cases, the filter base material is also used by imparting photosensitivity, but in this case, it is preferable that the photosensitivity characteristics of the filter base material and the optical characteristics of the materials of the intermediate layer and the protective layer are different. When processing the filter base material, it is necessary not to affect the materials of the intermediate layer and protective layer that exist below it. The following radiation-sensitive organic polymer materials are useful for use in the present invention. (1) Poly alkyl methacrylate or its copolymer However, R is an alkyl group, for example, CH 3 , C 4 H 9 (2) Polyglycidyl methacrylate or a copolymer thereof (3) Polymethacrylamide (4) Polymethylisopropenylketone (5) Poly(butene-1 sulfone) (6) Polyisobutylene It goes without saying that radiation-sensitive organic polymer materials other than these examples may be used. Of course, as the radiation-sensitive organic polymer material, those sensitive to ultraviolet rays, electron beams, X-rays, etc. can be used.
As used herein, the term "broadcast line sensitivity" includes these various types. [Embodiments of the Invention] The present invention will be described in detail below with reference to specific examples. 1 to 4 show the manufacturing process of the color solid-state image sensing device of the present invention. All are sectional views of the main parts of the elements. FIG. 5 is a plan view thereof. The color solid-state image sensor substrate 1 is provided with at least a large number of photodetecting sections 10 and a drive circuit section 11 for driving them. Note that the semiconductor substrate 1
The detailed structure inside has been omitted. Generally board 1
is made of silicon. The photodetector may be made of the same base material as the semiconductor integrated circuit that forms the peripheral circuitry for operating the photodetector, or may be made of a different type of semiconductor material. A layer of a base material of a color separation filter is formed to a thickness of about 0.5 to 2.5 μm on such a color solid-state image sensor substrate. This matrix is generally made of gelatin, egg white, green, casein, poval, or the like, which has been made photosensitive. As for photosensitive characteristics, it is common to use a negative type and have sensitivity in the range of 365 nm to 435 nm. By photo-curing and developing only the first color portion 2 of this layer using a mask exposure method, only the portion 2 of the color separation filter base material remains. This area is dyed with a dye having predetermined spectral characteristics. Note that the dyeing method may be a conventional method using an aqueous dye solution. In addition, when forming this layer of the filter base material of the first color, it is preferable to form a film of an organic polymer material on the surface of the substrate 1 to a thickness of about 0.5 to 1 μm. The surface of the substrate is further planarized by this coating of organic polymer material. This brings about the following advantages. (1) The semiconductor device portion provided in the substrate 1 is protected from contamination such as impurities. (2) The surface of the substrate 1 is flattened, making it easier to form the intermediate layer, filter base material layer, etc. formed on the top thereof, and preventing color mixing during dyeing, which occurs especially when the intermediate layer is deformed. You can. (3) In the color filter processing process, the area on which impurities adhere is reduced, which is useful for preventing contamination of semiconductor devices on the substrate. Note that it is advantageous for later processing to use a radiation-sensitive organic polymer material for forming the above-mentioned intermediate layer and the like as the organic polymer material. Next, a transparent dye-resistant intermediate layer 5 is formed to a thickness of 0.5~
Coat to 1.5μm. FIG. 1 shows this state. The aforementioned radiation-sensitive organic polymer material is used for this intermediate layer. In this case, as described above, it is preferable to select a material having radiation sensitivity characteristics different from those of the color separation filter base material. Next, as shown in FIG. 2, a layer of color filter base material is formed, exposed using a mask exposure method, and developed to form a second color filter portion 3, which has predetermined spectral characteristics. Dye with dye. Furthermore, a transparent intermediate layer 6 is coated. Furthermore, as shown in Figure 3, a color filter is applied.
