Sony patents camera sensor design that seals gaps in protective layers

Patent drawing from the official filing.

Sony describes a structure for a light detection device, such as a camera sensor, where a chip is covered by a buried layer. The design includes a specific seam in that layer and adds a sealing layer on top to cover the gap and protect the components.

Why it mattersThis is a routine improvement in how camera sensors are packaged and protected, which helps ensure the reliability of the hardware inside phones and cameras.

In the filing’s own words

A light detection device includes: a substrate including a light detection element; a chip provided for the substrate; a buried layer provided to cover the chip; a seam portion occurring in the buried layer and extending to a front surface of the buried layer; and a sealing layer provided to cover the buried layer and the seam portion.

What exactly they claim (claim 1)

1. A light detection device comprising: a substrate including a light detection element; a chip provided for the substrate; a buried layer provided to cover the chip; a seam portion occurring in the buried layer and extending to a front surface of the buried layer; and a sealing layer provided to cover the buried layer and the seam portion.
