OPTICAL ELEMENT WITH DISTANT LAYER
Document Type and Number:
WIPO Patent Application WO/2024/082212
Kind Code:
A1
Abstract:
An optical element including a substrate (210), a light sensing device (220) disposed in the substrate (210); a first distant layer (230) disposed above the substrate (210), wherein a coefficient of thermal expansion of the first distant layer (230) is between 10 ppm/℃ and 300 ppm/℃, and wherein an angle between a sidewall of the first distant layer (230) and a top surface of the substrate (210) is in a range of 10° to 60°; and an inorganic multilayer film (240) covering a top surface and the sidewall of the first distant layer (230), wherein a coefficient of thermal expansion of the inorganic multilayer film (240) is between 0.5 ppm/℃ and 30 ppm/℃.
