Latest Patents
Aoki's latest patents include a solid-state imaging device and a method of manufacturing the same. This invention addresses the challenge of light entering the device obliquely. The design incorporates a second microlens that gathers light passing an optical path that misses the photodiode part, directing it more vertically. This approach prevents the convergent rate of oblique incident light from decreasing, resulting in a solid-state imaging device with a high sensitivity ratio, reduced smear, and excellent image characteristics. Additionally, a metal with a high melting point or a metal silicide film is utilized as a photo-shielding film. After thinning the photo-shielding film, a Boro-Phospho-Silicate-Glass (BPSG) film is applied to the entire surface. The second microlens is formed on an element with a protective coating, followed by the addition of a color filter and an intermediate transparent film, culminating in the formation of a first microlens. The second microlens is crafted from a material with a higher refractive index than that of the intermediate transparent film or the BPSG film.
