Image sensing device |
摘要 |
An image sensing device includes: a semiconductor substrate with a photo-sensing element; a passive layer disposed over the semiconductor substrate, having a first refractive index; a color pattern disposed over the passive layer, wherein the color pattern aligns to the photo-sensing element and has a color selected from the group consisting of red (R), green (G), blue (B), and white (W), and a second refractive index; and an electromagnetic wave guiding element disposed in at least one of the color pattern and the passive layer, having a third refractive index, and the third refractive index is greater than the first refractive index or the second refractive index, and a first difference between the third refractive index and the first refractive index is at least 0.2, and a second difference between the third refractive index and the second refractive index is at least 0.2. |

1. An image sensing device, comprising:
a semiconductor substrate with a photo-sensing element; a passive layer disposed over the semiconductor substrate, having a first refractive index; a color pattern disposed over the passive layer, wherein the color pattern aligns to the photo-sensing element and has a color selected from the group consisting of red (R), green (G), blue (B), and white (W), and a second refractive index; and an electromagnetic wave guiding element disposed in at least one of the color pattern and the passive layer, wherein the electromagnetic wave guiding element has a third refractive index, and the third refractive index is greater than the first refractive index or the second refractive index, and a first difference between the third refractive index and the first refractive index is at least 0.2, and a second difference between the third refractive index and the second refractive index is at least 0.2, wherein a top surface area of the electromagnetic wave guiding element is substantially equal to or less than a bottom surface area of the electromagnetic wave guiding element. |
