Problems solved by technology

[0003] The inventors of the present application have discovered during long-term research that, on the one hand, since the thickness of the transparent glass cover plate is generally thick, refraction, reflection and energy loss will occur when the light passes through the transparent glass, which will make the photosensitive effect of the chip worse; On the other hand, the transparent glass cover and the chip are connected by glue. After a long time of use, the glue is easy to fall off, and the external dust is easy to enter the photosensitive area of ​​the chip, which will affect the photosensitive effect of the chip.

Abstract

The invention discloses a semiconductor packaging device, and the semiconductor packaging device comprises a chip which comprises a front surface and a back surface, wherein the front surface of the chip is provided with a photosensitive area and a plurality of bonding pads located around the photosensitive area, and the chip is provided with through holes which are corresponding to the positionsof the plurality of the bonding pads in a one-to-one manner; a transparent protective layer which is located on the front surface of the chip and covers the photosensitive of the chip and the plurality of bonding pads; and a circuit board which is electrically connected to the plurality of the bonding pads of the chip through the through holes. Through the above manner, the device can improve thelight sensing effect of the chip.

Description

technical field [0001] The present application relates to the technical field of semiconductors, in particular to a semiconductor packaging device. Background technique [0002] A chip with a photosensitive area is a very important part of an imaging device. In order to protect the photosensitive area of ​​the chip, a commonly used packaging method includes: adding a transparent glass cover above the photosensitive area of ​​the chip to protect the photosensitive area of ​​the chip. [0003] The inventors of the present application have discovered during long-term research that, on the one hand, since the thickness of the transparent glass cover plate is generally thick, refraction, reflection and energy loss will occur when the light passes through the transparent glass, which will make the photosensitive effect of the chip worse; On the other hand, the transparent glass cover and the chip are connected by glue. After a long time of use, the glue is easy to fall off, and ex...
