- cohesive failure occurs in the seal resin 301 in contact with the underfill material 213 due to curing shrinkage stress when the underfill material 213 is thermally cured, and cracks 302 may occur.
- cohesive failure occurs in the seal resin 301 in contact with the underfill material 213 due to curing shrinkage stress when the underfill material 213 is thermally cured, and cracks 302 may occur.
- the whitening of the sealing resin 301 due to the cracks 302 reaches the periphery of the on-chip lens 256, light is diffusely reflected at the whitened portion, degrading the image quality of the captured image.
- the light reflected by the on-chip lens 256 and the surface of the silicon substrate 253 is totally reflected by the upper surface (surface) of the protective substrate 232, and re-enters the light receiving region of the silicon substrate 253 where the photodiodes are formed.
- a periodic diffraction ghost or diffraction flare may occur in the captured image.
- the seal resin 301 and the protective substrate 232 have substantially the same refractive index, the light reflected by the surface of the on-chip lens 256 and silicon substrate 253 travels straight to the surface of the protective substrate 232 away from this surface. Therefore, due to the light totally reflected by the protective substrate 232 , a strong diffraction ghost may be generated at a position distant from the reflection position on the surface of the on-chip lens 256 or silicon substrate 253 .
- Such diffraction ghosts and diffraction flares are unintended reflections of light, that is, noise, and are undesirable.
- FIG. 4 is an enlarged view of rectangle A in FIG.
- the sealing resin 231 has a composite structure including randomly dispersed reinforcing materials 352 having a higher Young's modulus or breaking strength than the base material 351 .
- the sealing resin 231 contains the reinforcing material 352 , the sealing resin 231 can be reinforced more than the sealing resin 301 . Therefore, cohesive failure of the seal resin 231 due to curing shrinkage stress when the underfill material 213 is thermally cured can be suppressed. As a result, occurrence of whitening of the seal resin 231 is reduced, and deterioration of image quality of the captured image due to this whitening is suppressed.
- the cracks 371 can be stopped at the interface of the reinforcing material 352 . Therefore, it is possible to prevent the crack 371 from growing around the on-chip lens 256, that is, on the light receiving area. As a result, the whitening of the sealing resin 231 can be prevented from adversely affecting the image quality of the captured image.
- the semiconductor chip 211 is protected by the underfill material 213 to ensure long-term reliability after the semiconductor chip 211 is mounted on the substrate 212, while the whitening of the seal resin 231 prevents deterioration of image quality of captured images. can be suppressed.
- the seal resin 231 is configured, for example, so that the average transmittance in the visible light wavelength range (for example, 400 nm to 700 nm) is 98.5% or higher.
- the base material 351 is an acrylic sealing resin having a refractive index lower than that of the on-chip lens 256 and substantially equal to that of the protective substrate 232 .
- the protective substrate 232 is a glass substrate with a refractive index of 1.51
- the base material 351 is, for example, acrylic resin with a refractive index of 1.5.
- the seal resin 231 since the refractive index of the base material 351 is lower than that of the on-chip lens 256, the light condensing property of the on-chip lens 256 can be improved. Moreover, since the protective substrate 232 and the base material 351 have substantially the same refractive index, the influence of the base material 351 on the light incident on the light receiving region through the protective substrate 232 can be suppressed.
- the reinforcing material 352 is a fibrous material that transmits visible light.
- examples of such materials include glass fibers, cellulose nanofibers, and organic fibers such as nanoparticle aggregates having a particle size of 100 nm or less.
- Cellulose nanofibers are transparent cellulose fibers thinned to the nano level, which are formed by hydrolyzing and pulverizing wood or the like. Cellulose nanofibers, for example, are five times stronger than steel.
- the cross-sectional diameter of the short side of the reinforcing material 352 is shorter than the wavelength of visible light, and the cross-sectional diameter of the long side is three times or more the cross-sectional diameter of the short side, that is, the aspect ratio is 3 or more. Thereby, the influence of the reinforcing material 352 on the light incident on the light receiving region through the protective substrate 232 can be suppressed.
- the refractive index of the reinforcing material 352 is approximately equal to the refractive index of the base material 351. Specifically, it is desirable that the difference in refractive index between the reinforcing material 352 and the base material 351 is, for example, 0.03 or more and 0.06 or less. If the difference in refractive index between the reinforcing material 352 and the base material 351 is 0.06 or less, the effect of the reinforcing material 352 on the light incident on the light receiving region through the protective substrate 232 can be suppressed. As a result, deterioration of image quality due to the reinforcing material 352 can be suppressed.
- the difference in refractive index between the reinforcing material 352 and the base material 351 is 0.03 or more, as shown in FIG. change direction.
- the light is reflected by the light receiving area and the on-chip lens 256, enters the protective substrate 232 through the sealing resin 231, is totally reflected by the upper surface of the protective substrate 232, and enters the light receiving area again through the sealing resin 231 and the like. It is possible to suppress the occurrence of the phase shift of the light to be emitted. As a result, it is possible to reduce the occurrence of diffraction ghosts (brightness and darkness of light) and diffraction flare in captured images due to this phase shift. Thereby, the image quality of the captured image can be improved.
