Abstract
An image pickup device includes a pixel array including a plurality of photo sensitive devices and a color filter array including a plurality of color filters each disposed above a corresponding one of the plurality of photo sensitive devices. The color filters include a first type color filter formed on a glass substrate to filter light to pass a first spectrum and a second type color filter stacked on at least part of the first type color filter to filter light to pass a second spectrum. Accordingly, fabrication of a color filter array can be simplified and a color filter array having a small lay out can be fabricated.
Claims20
A method of fabricating a color filter array, the method comprising:
- forming, on a glass substrate, a first type color filter to filter light to pass a spectrum of a first color;
- forming a second type color filter stacked on at least part of the first type color filter to filter light to pass a spectrum of second color;
- and
- forming an insulating layer on the color filter array, the color filter array including color filters only of the first type and the second type.
A color filter array comprising:
- a glass substrate;
- a first type color filter formed on the glass substrate, the first type color filter being configured to filter light to pass a spectrum of a first color;
- and
- a second type color filter stacked on at least part of the first type color filter, the second type color filter being configured to filter light to pass a spectrum of a second color;
- and
- an insulating layer covering the first type color filter and the second type color filter,
- wherein the color filter array includes color filters only of the first type and the second type.
