Title:
PHOTOSENSITIVE ASSEMBLY AND METHOD FOR FORMING SAME, LENS MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/087595
Kind Code:
A1
Abstract:
Disclosed are a photosensitive assembly and a method for forming same, a lens module and an electronic device. The method for forming a photosensitive assembly (510) comprises: providing a light-transmitting cover plate (30, 200); providing a photosensitive chip (10, 400), wherein the photosensitive chip comprises a photosensitive area (10a, 400a) and a peripheral area (10b, 400b) encircling the photosensitive area (10a, 400a); attaching the light-transmitting cover plate (30, 200) to the photosensitive chip (10, 400) by means of a bonding layer (20, 300), wherein the bonding layer (20, 300) is located within the peripheral area (10b, 400b), and the light-transmitting cover plate (30, 200), the bonding layer (20, 300) and the photosensitive chip (10, 400) encircle a cavity (25, 350) accommodating the photosensitive area (10a, 400a); forming a sealing layer (500) which at least covers a side wall of the bonding layer (20, 300) and a side wall of the light-transmitting cover plate (30, 200); and increasing the sealing performance of the cavity (25, 350). In the subsequent packaging process, the sealing layer (500) can prevent a solution, such as water, from entering the cavity (25, 350), thereby improving the waterproof ability of the photosensitive assembly (510) and the reliability of the lens module.
